MCP3427-E/UN - 16-Bit Dual-Channel Delta-Sigma ADC | Microchip
MCP3427-E/UN

MCP3427-E/UN - 16-Bit Dual-Channel Delta-Sigma ADC | Microchip

The Microchip Technology MCP3427-E/UN is a 16-bit dual-channel delta-sigma analog-to-digital converter with differential inputs, a 15 samples-per-second conversion rate, and a 10-MSOP package. It operates from a 3.3 V or 5 V supply and incorporates an on-board precision 2.048 V reference, providing a differential input range of ±2.048 V. The device communicates through an I2C interface for compact, low-noise measurement systems. A delta-sigma ADC is a category of analog-to-digital converter that uses continuous-time oversampling and digital filtering to convert analog input voltages into high-resolution digital codes. Its hierarchy extends from an ADC to a data-acquisition component and ultimately to a signal-chain semiconductor. Compared with flash converters, this architecture is especially useful when low noise, high effective resolution, and integrated differential input handling matter more than very high conversion speed. The MCP3427-E/UN combines two measurement channels with 16-bit resolution in one compact device. Its differential inputs help reject common-mode noise when the sensor or bridge output is centered around a biased reference. The integrated 2.048 V reference simplifies measurement designs that do not require an external precision reference, while the 15 sps rate suits slowly changing industrial, instrumentation, and sensor signals rather than high-bandwidth waveform acquisition. Each channel is processed by the converter’s delta-sigma architecture and exposed through the I2C interface. This makes the MCP3427-E/UN appropriate for systems that need accurate readings rather than rapid sampling. The 10-MSOP package also supports compact PCB layouts, although engineers must follow the manufacturer's layout guidance to preserve the low-noise performance of the analog inputs and reference circuitry. Typical uses include bridge-based pressure and load measurements, industrial process monitoring, portable instrumentation, and low-frequency sensor acquisition. Differential sensing is particularly valuable when a transducer produces a small signal riding on a larger common-mode voltage. The 3.3 V or 5 V operation also allows integration with both low-voltage embedded systems and conventional industrial control platforms. When designing around the MCP3427-E/UN, verify the selected conversion rate, digital filter behavior, input range, and reference configuration against the manufacturer datasheet. Input filtering, grounding, and I2C pull-up placement can materially affect a sensitive measurement, so the analog and digital return currents should be routed to avoid shared high-impedance paths. This product record combines the verified Microchip product information, distributor availability, package details, and same-family drop-in options. It also adds application guidance, selection criteria, and design notes intended to make the MCP3427-E/UN easier to evaluate than a distributor listing alone.

MCP3428-E/SL - 16-Bit 4-Channel ADC | Microchip
MCP3428-E/SL

MCP3428-E/SL - 16-Bit 4-Channel ADC | Microchip

Microchip Technology MCP3428-E/SL is a four-channel, low-noise, high-accuracy delta-sigma analog-to-digital converter with differential inputs, up to 16-bit resolution, a 2.048 V precision internal reference, and a 14-pin SOIC package. The supported conversion rate reaches 240 samples per second, while its single supply operating range is 2.7 V to 5.5 V. The device uses a two-wire I2C-compatible serial interface for compact measurement systems. A delta-sigma ADC is a type of analog-to-digital converter that uses continuous-time oversampling and digital filtering to convert differential input voltages into high-resolution digital codes. Within the broader semiconductor hierarchy, the MCP3428 belongs to the ADC/DAC class and provides precision measurement functions for instrumentation, industrial controls, and low-frequency sensor acquisition. The MCP3428-E/SL supports four differential channels, resolution up to 16 bits, and a precision 2.048 V on-board reference. Differential input range extends to plus or minus 2.048 V when the internal reference is used. Its 240 SPS maximum conversion rate is suited to slow-changing analog quantities rather than high-bandwidth waveform acquisition, while the low-noise architecture helps preserve accuracy in bridge, potentiometer, temperature, and pressure measurements. Technically, the ADC combines delta-sigma conversion with an I2C-compatible control interface and onboard reference. Differential inputs reject common-mode noise when paired appropriately, and the internal reference reduces external-reference count in moderate-accuracy designs. The 2.7 V to 5.5 V supply range supports both 3.3 V and 5 V systems, although the selected interface voltage and available I2C bus limits must be checked during integration. Typical uses include industrial pressure and temperature acquisition, low-rate strain and bridge conditioning, potentiometer position sensing, battery-cell monitoring, laboratory measurement, and environmental monitoring. For high-speed motor control, audio sampling, or wideband vibration analysis, a higher-rate SAR or sigma-delta converter would generally be more appropriate. Designers should verify the input common-mode range and the datasheet configuration sequence before applying external signals. Place input and reference decoupling capacitors close to their pins, route analog inputs away from switching nodes, and confirm that I2C pull-up resistors satisfy the bus capacitance and rise-time requirements at the selected clock rate. This page combines verified manufacturer and distributor information, structured specification gaps, a package-aware comparison, and practical integration guidance. It also distinguishes verified ordering variants from genuine pin-compatible replacements so engineers can assess interchangeability without assuming that a similar converter is automatically a drop-in substitute.

MCP3428-E/ST - 16-Bit 4-Channel Sigma-Delta ADC | Microchip
MCP3428-E/ST

MCP3428-E/ST - 16-Bit 4-Channel Sigma-Delta ADC | Microchip

The Microchip Technology MCP3428-E/ST is a four-channel, 16-bit delta-sigma analog-to-digital converter with differential inputs, an I2C interface, and a 14-TSSOP package. It operates from 3.3 V or 5 V, supports conversion rates up to 15 samples per second, and incorporates a precision 2.048 V internal reference. Its differential input range of ±2.048 V is useful for low-level sensor signals, while the four-channel architecture reduces the number of separate converters required in multi-sensor measurement systems. An analog-to-digital converter, or ADC, is an interface IC that converts continuous analog voltage into a numerical value suitable for processing by a microcontroller or embedded control system. The MCP3428 belongs to the delta-sigma ADC family within the broader analog and mixed-signal semiconductor hierarchy. Delta-sigma conversion is especially useful when high resolution, low noise, and relatively slow measurement are more important than very high conversion speed. The MCP3428 provides up to 16-bit resolution, four differential input channels, a 2.048 V precision reference, and a maximum 15 sps conversion rate. Its I2C interface allows a host controller to configure conversion settings and retrieve results, while the on-board reference reduces the external precision-component count. These characteristics make the device useful for temperature, pressure, strain, current, and other slowly changing industrial measurements. Its four differential inputs can reject common-mode noise when the source and return paths are routed carefully. The architecture is particularly valuable in sensors whose outputs are small relative to system supply voltage. The 14-TSSOP package also supports compact PCB layouts, although the exposed signal and reference connections require clean grounding and stable analog supply arrangements. Typical uses include process-control instrumentation, environmental monitoring, industrial sensor acquisition, laboratory measurement, and low-rate energy metering. MCP3428T-E/ST and other MCP342x family members may be considered when pin compatibility, resolution, or temperature-range requirements differ, but every substitute must be checked against the exact pinout, reference behavior, interface timing, and acquisition-cycle requirements. For implementation, use short analog traces, a quiet reference return, and decoupling close to VDD and VSS. Confirm the source impedance and settling time because the 15 sps maximum rate leaves limited time for the selected conversion cycle. Digital interface traces should be kept away from sensitive input and reference nodes to prevent I2C activity from coupling into measured voltages. This page consolidates the verified manufacturer and distributor information, separates known variants from true drop-in options, and adds engineering guidance on acquisition timing, grounding, decoupling, and replacement decisions. Those practical details help distinguish a nominal specification match from a design that can be qualified with confidence.

MCP3428T-E/SL

MCP3428T-E/SL - 16-Bit 4-Channel Delta-Sigma ADC | Microchip

The Microchip Technology MCP3428T-E/SL is a four-channel, 16-bit delta-sigma analog-to-digital converter with differential inputs, a 15 sample-per-second conversion rate, and a 14-SOIC package. Its integrated precision 2.048 V reference supports a differential input range of ±2.048 V, while the two-wire I2C interface provides a compact connection to embedded control systems. A delta-sigma ADC is a mixed-signal data converter that uses oversampling and digital filtering to provide high resolution and low noise in narrow-bandwidth measurements. The MCP3428 belongs to the ADC and DAC > Analog-to-digital converter product hierarchy and is suited to precision acquisition systems rather than high-speed waveform capture. Its conversion architecture prioritizes accurate, stable readings from slowly changing or low-frequency sensor signals. The MCP3428 provides four differential input channels, 16-bit resolution, a 2.048 V precision internal reference, and a specified conversion rate of 15 SPS. Differential inputs reject common-mode noise when paired with suitable sensor bridges or instrumentation amplifiers. The integrated reference reduces external component count, while the I2C interface allows the converter to share a two-wire bus with sensors, EEPROM, and other compatible peripherals. The -E/SL ordering option is associated with the automotive-grade AEC-Q100 qualification indicated in the product documentation and uses a 14-pin SOIC package. Tape-and-reel packaging supports automated production and pick-and-place assembly. The SOIC body is listed at 3.90 mm width, and the gull-wing terminal form is compatible with conventional surface-mount assembly and board-level inspection processes. Typical uses include industrial pressure and temperature acquisition, bridge-sensor measurement, laboratory instrumentation, battery monitoring, and embedded environmental sensing. Differential channel pairing is particularly useful when the measured quantity is represented by a small voltage difference riding on a larger common-mode voltage. Firmware must configure the input channel, gain, resolution, and conversion timing through the device's serial register interface. Designers should allow the digital filter and continuous-conversion settling behavior to determine the valid sampling interval. Input filtering, reference bypassing, grounding, and I2C pull-up placement are as important as ADC resolution because they determine whether system-level accuracy approaches the converter's intrinsic performance. This page combines manufacturer specifications, application guidance, drop-in family comparisons, and practical design considerations to support component selection, schematic planning, PCB layout, and sourcing decisions for the MCP3428T-E/SL.

Within the signal-chain hierarchy, the MCP3461-E/ST belongs to the ADC and data-acquisition converter family, combining an analog input stage, sigma-delta modulator, digital filter, and serial interface in one low-noise device. Integrated functions help reduce the number of external components required in a measurement system. The MCP3461/2/4R family includes an internal voltage reference, internal oscillator, temperature sensor, and burnout-sensor detection. The MCP3461-E/ST also offers programmable output data rates up to 153.6 kSPS, making it suitable for sensors, process-control measurements, and industrial data-acquisition systems that prioritize resolution over very high conversion latency. The converter uses a delta-sigma architecture to achieve 16-bit nominal resolution while rejecting out-of-band noise through its digital decimation filter. The MCP3461R version is identified by Microchip as a preferred, pin-compatible option for new designs because it includes an onboard voltage reference that is not included in the MCP3461. Engineers should therefore verify the selected suffix and external reference configuration before making a direct substitution. Typical uses include bridge and pressure sensor interfaces, temperature measurement, industrial process monitoring, laboratory instrumentation, and embedded data-acquisition systems. Its integrated reference, oscillator, temperature sensor, and burnout detection are especially useful where component count, calibration overhead, and predictable operation matter. The principal design consideration is matching the input, reference, and digital interface requirements to the exact MCP3461 variant. MCP3461-E/ST and MCP3461R-E/ST share the 20-pin TSSOP footprint, but the R version adds an internal voltage reference; firmware, reference selection, and board-level requirements must be reviewed before interchange. Filtering characteristics, data rate, and digital timing should also be evaluated for the target measurement bandwidth. This page consolidates verified manufacturer and distributor information, package details, lifecycle status, sourcing data, and practical selection guidance. It also distinguishes true same-footprint alternatives from broader functional equivalents so engineers can identify which substitutions require additional design review.

It operates from a 2.7 V to 3.6 V analog supply and a 1.8 V to 3.7 V digital supply, providing a compact converter for precision industrial, instrumentation, and sensor-measurement systems. A delta-sigma ADC is a category of data-converter IC that uses continuous-time oversampling and digital filtering to obtain high resolution and excellent noise performance. Its role within the broader semiconductor hierarchy is analog-to-digital converter, data-acquisition IC, signal-chain component, and ultimately electronic measurement interface. The MCP3461R-E/ST is designed to digitize low-frequency analog signals where fine resolution, stable conversion performance, and low circuit complexity are more important than very high sample rates. Key device characteristics include 16-bit resolution, an output data rate of up to 153.6 kSPS, one differential input or two single-ended inputs, an SPI interface, an internal voltage reference, an internal oscillator, a programmable gain amplifier, and an integrated temperature sensor. Typical signal-to-noise ratio is 97.3 dB, while typical integral nonlinearity is 7 ppm. The converter also supports clock frequencies from 1 MHz to 20 MHz or from 3.3 MHz to 6.6 MHz, depending on the operating mode. The delta-sigma conversion architecture filters noise through oversampling and digital decimation, making the device appropriate for pressure, temperature, level, load-cell, and laboratory measurement signals. Its internal reference and oscillator reduce external component count, while the 20-pin TSSOP package simplifies routing in compact data-acquisition boards. The SPI interface supports deterministic communication with a host microcontroller or digital controller. Typical uses include industrial process monitoring, precision temperature measurement, pressure transducers, portable instrumentation, low-frequency sensor acquisition, and embedded data loggers. For applications requiring more independent analog inputs, related four-channel and dual-channel members of the MCP346x family can provide additional channel capacity, but software configuration, pin allocation, and acquisition sequencing must be checked before substitution. When designing a board around the MCP3461R-E/ST, place the input, reference, and decoupling networks close to the device and keep sensitive analog traces short and separated from digital switching paths. Select the clock and decimation settings so that the resulting output-data rate meets the signal bandwidth without sacrificing the required noise performance. Account for the 2.7 V minimum analog supply when designing the sensor interface and reference headroom. This product page combines the manufacturer specifications with application guidance, parameter comparisons, and clearly qualified drop-in options. It helps engineers evaluate channel count, reference configuration, temperature range, package compatibility, interface behavior, and power-supply requirements before committing the MCP3461R-E/ST to a production design.

The converter operates from a 2.7 V to 3.6 V analog supply and a 1.8 V to 3.7 V digital supply. A delta-sigma ADC is a signal-processing category of analog-to-digital converter that continuously oversamples and digitally filters its input. Unlike a flash or successive-approximation ADC, the MCP3462 trades conversion latency for high resolution, low noise, and integrated signal conditioning. It belongs to the broader ADC > data converter > mixed-signal semiconductor hierarchy and is intended for precision measurement rather than high-speed waveform capture. Key features include 16-bit resolution, four single-ended or two differential inputs, and a maximum programmable data rate of 153.6 kSPS. Integrated resources include an internal oscillator, programmable gain amplifier, temperature sensor, and digital interface functions described by the manufacturer. The MCP3462 uses an external voltage reference, while the pin-compatible MCP3462R adds an onboard reference and is identified by Microchip as the preferred option for new designs. The MCP3462 combines a delta-sigma conversion core with programmable input gain and flexible data acquisition modes. Its internal oscillator reduces the need for an external clock source, while the temperature sensor supports system-level monitoring. The dual differential-input architecture allows common-mode rejection of paired sensors, and the four single-ended channels permit multiplexing for multi-sensor systems. The 2.7 V minimum analog supply supports low-voltage industrial instrumentation, although the analog and digital operating ranges must remain within their respective limits. Typical uses include industrial process measurement, battery and power-system monitoring, environmental sensing, portable instrumentation, and low-frequency precision data acquisition. The integrated temperature sensor can assist with board-level thermal monitoring, while the programmable gain amplifier supports inputs that vary substantially in amplitude. Because the device is a delta-sigma ADC, software or digital filtering and a settling-time budget must be considered when measuring rapidly changing signals. The principal design consideration is reference quality. The MCP3462 requires an external reference, and reference noise, layout distance, and input filtering directly influence conversion results. Place the analog inputs, external reference, and associated bypass components close to the converter, keep digital interfaces away from sensitive analog inputs, and follow the manufacturer’s recommended decoupling and grounding arrangement. This page combines manufacturer positioning, distributor availability, verified package and channel information, pin-compatible same-family alternatives, and practical selection guidance. It also distinguishes the externally referenced MCP3462 from the onboard-reference MCP3462R so engineers can choose the appropriate variant without treating every TSSOP ADC as an interchangeable replacement.

The -E grade extends operation from -40 °C to +125 °C and the -ST suffix denotes the 20-lead TSSOP package. A delta-sigma ADC is a type of analog-to-digital converter that uses a sigma-delta modulator to shape quantization noise into the out-of-band region, where it is removed by a digital decimation filter. Within the broader hierarchy of data converter ICs -> analog-to-digital converter -> data acquisition building block -> semiconductor, this architecture is the standard choice for high-resolution, low-bandwidth measurement of slowly varying or slowly changing analog signals such as temperature, pressure, load-cell bridge outputs, and battery voltage. Key features of the MCP3462R include 16-bit resolution, a maximum 153.6 kSPS conversion rate, an internal 2.048 V-class voltage reference with an internal oscillator, a programmable gain amplifier (PGA), an integrated temperature sensor, and burnout sensor detection for open-circuit diagnostics. A typical SNR of 97.3 dB and flexible digital interface handling let the same part cover industrial process control, energy metering, and portable instrumentation. The analog supply operates from 2.7 V to 3.6 V while the digital supply accepts 1.8 V to 3.7 V, which lets the ADC interface directly to 1.8 V microcontrollers and 3.3 V logic without level translators. The serial interface supports SPI-compatible framing, and the integrated reference and oscillator remove the external precision reference and crystal normally required, reducing board area and total solution cost. Typical applications include precision temperature sensing with RTDs and thermocouples, load-cell and strain-gauge front ends, industrial data acquisition modules, battery-powered portable instrumentation, and energy metering where a low-noise 16-bit conversion with built-in diagnostics is needed. When designing with the MCP3462R-E/ST, keep analog and digital return currents separated and place the input RC filter close to the VIN pins. The internal reference and internal oscillator simplify the BOM, but for the lowest gain error across temperature the external reference option should be evaluated against the accuracy target of the end measurement. This page consolidates parametric detail, package and pin information, drop-in replacement candidates, application guidance, and practical design notes into one reference so that design, sourcing, and review teams can evaluate the MCP3462R-E/ST without piecing the data together from multiple listings.

The Microchip Technology MCP3464-E/ST is a 16-bit quad-channel delta-sigma analog-to-digital converter (ADC) designed for 3 V supply operation, packaged in a 20-pin gull-wing TSSOP (ST) surface-mount package. A delta-sigma ADC is a type of analog-to-digital converter that uses a sigma-delta modulator and a digital decimation filter to convert an analog voltage into a high-resolution digital word. This architecture trades conversion speed for excellent noise performance and linearity, which makes it a favored member of the ADC family hierarchy: ADC -> delta-sigma ADC -> sigma-delta modulator -> high-resolution mixed-signal converter for low-bandwidth, high-precision measurement. Key features of this device include 16-bit resolution across four analog input channels, a differential-capable sigma-delta conversion core, a 3 V supply rail for low-voltage system compatibility, and an automotive temperature grade designation according to distributor listings. Because the converter operates as a delta-sigma type ADC, it suits slow-moving analog signals such as temperature, pressure, load-cell, and bridge-sensor outputs where integration averages out wideband noise. An important design note from Microchip is that the MCP3464R variant, which includes an onboard voltage reference, is the preferred pin-compatible option for new designs; the MCP3464 itself requires an external reference. Typical applications include industrial process-control instrumentation, medical monitoring equipment, automotive sensor acquisition, energy-metering subsystems, and precision data-acquisition modules where 16-bit resolution, low noise, and simple single-chip signal conditioning reduce the need for external analog front ends. When designing around the MCP3464-E/ST, verify the reference-voltage requirement against your system: an external low-noise reference and proper input filtering are mandatory because the converter has no internal voltage reference. Decouple the supply pin close to the device, keep analog and digital return currents separated, and confirm the full conversion timing against your host sampling rate before committing to a multiplexed channel schedule. This page consolidates distributor pricing, pin-compatible Microchip drop-in alternatives, and practical application and layout guidance that is not assembled from a single manufacturer datasheet, giving engineers a single decision-ready reference for this quad-channel 16-bit delta-sigma ADC.

It is designed for precision measurement systems that need high resolution, flexible input configuration, and an SPI-compatible serial interface. A delta-sigma ADC is a voltage-to-digital converter category that uses oversampling, noise shaping, and digital filtering to obtain high effective resolution from a compact analog front end. Within the broader semiconductor hierarchy, the MCP3464 belongs to the ADC family, sits under data-converter ICs, and ultimately serves industrial measurement, instrumentation, and embedded-control applications. Its four-channel architecture supports simultaneous acquisition of multiple sensor outputs without requiring four separate converter packages. The MCP3464T-E/ST combines 16-bit nominal resolution with programmable conversion rates up to 153.6 kSPS. The manufacturer describes the device as a low-noise converter with four differential or eight single-ended inputs, providing flexibility for bridge sensors, voltage inputs, and mixed measurement systems. Its SPI interface supports integration with microcontrollers and digital signal controllers while keeping conversion data and configuration controls on a compact serial bus. The converter family includes related four-channel devices distinguished by integrated voltage-reference and packaging options. The manufacturer specifically identifies MCP3464R as the preferred pin-compatible choice for new designs because it includes an onboard voltage reference that is not present in MCP3464. This distinction is important when deciding whether the original MCP3464T-E/ST remains appropriate for a board under revision or whether a new design should adopt the referenced configuration. The MCP3464T-E/ST is appropriate for industrial process monitoring, precision sensor acquisition, laboratory instrumentation, and embedded data acquisition. Its nominal 16-bit resolution suits measurements requiring more detail than an 8-bit or 12-bit converter, while the 153.6 kSPS maximum rate permits faster sampling than many low-speed high-resolution converters. For a robust implementation, confirm the external reference requirements, analog input voltage range, digital interface levels, and selected output-data format against the manufacturer datasheet. The four-channel TSSOP footprint also requires a layout that separates sensitive analog inputs from SPI activity and provides suitable return paths for analog and digital return currents. This product page combines the manufacturer product description, distributor identification, and package-level comparison data with practical selection guidance. It also distinguishes the original MCP3464T-E/ST from pin-compatible family members that add an onboard reference, helping engineers evaluate PCB reuse without overlooking functional changes.

An ADC is a data-conversion device that transforms a continuous analog voltage into a digital code for processing by a microcontroller, DSP or host controller. Within the product hierarchy, this part belongs to the delta-sigma ADC class, which uses oversampling and digital filtering to deliver high resolution and excellent noise performance from a low bandwidth. The MCP3465 sits in the broader category of data-converter ICs, inside integrated circuits, inside semiconductors, and ultimately inside the wider electronic-component supply chain. Key characteristics include 16-bit nominal resolution, a single analog input channel, a 3 V supply domain and a UQFN-12 surface-mount package. Because it uses a delta-sigma architecture, the converter trades conversion speed for noise rejection and linearity, which is exactly what thermocouple, bridge, ratiometric sensor and general slow-changing analog signal measurements need. The small package keeps the analog front end close to the sensor on the board. The internal conversion chain uses a sigma-delta modulator followed by digital decimation filtering, so the effective noise bandwidth is narrowed far below the modulator sample rate. This is why the device performs well when the input signal is slowly varying and when the analog board is electrically noisy. Differential-style ratiometric measurements cancel supply drift and reference-gain error, which matters when the excitation current comes from the same supply as the converter. Typical applications include industrial process monitoring, portable medical instrumentation, load-cell and pressure bridge front ends, battery-powered data loggers, and consumer or IoT sensor hubs that need more resolution than an internal MCU ADC can deliver at low cost. The device also suits laboratory and test equipment where traceable measurement performance is required in a compact board area. A key design consideration is that delta-sigma ADCs need a clean reference and stable layout. Place the decoupling capacitors close to the supply and reference pins, keep analog traces short and away from switching nodes, and treat the analog ground return as a separate, low-impedance path to the regulator. Because the digital filter has a settling time, read the data-ready signal before issuing the next conversion instead of polling at a fixed delay. This page consolidates package, ordering-code and sourcing detail for the MCP3465T-E/QM together with drop-in replacement options in the same UQFN-12 footprint, a parameter-by-parameter comparison, and practical layout and application guidance that engineers can apply directly to a new analog board.

MCP3551-E/MS - 22-Bit Low-Noise Delta-Sigma ADC | Microchip
MCP3551-E/MS

MCP3551-E/MS - 22-Bit Low-Noise Delta-Sigma ADC | Microchip

The Microchip Technology MCP3551-E/MS is a 22-bit, single-channel delta-sigma analog-to-digital converter with a fully differential input, an internal oscillator, and a conversion rate of 13.75 samples per second, housed in an 8-pin MSOP package. The converter supports supply operation from 2.7 V and is designed for applications requiring high accuracy, low noise, and low-power signal acquisition. Its output noise is specified as low as 2.5 uVRMS, while total unadjusted error is reported as 10 ppm. A delta-sigma ADC is a voltage regulator and signal-processing technique in which a continuously operating internal modulator oversamples the input before digital filtering and decimation. The MCP3551 belongs to the ADC, data-converter, and analog-signal-processing semiconductor hierarchy. Its low output rate and high nominal resolution favor measurements that change slowly, making it particularly useful for industrial process-control loops, bridge sensors, and precision analog instrumentation rather than high-bandwidth waveform capture. The principal benefits of the MCP3551-E/MS include 22-bit resolution, a fully differential analog input, low output noise, a 10 ppm total unadjusted error, and an internal oscillator that avoids an external clock source. The single input supports one analog measurement channel, while the delta-sigma architecture filters high-frequency content through oversampling and digital decimation. Its 2.7 V minimum supply voltage also permits use in compact, low-power measurement systems. The MCP3551 family combines a sigma-delta conversion stage with an internal oscillator and digital signal processing. The verified comparison data identifies the MCP3551 as a low-power, single-channel converter and lists a 2.7 V operating supply. Because the device uses a fully differential input, the source circuit must present two input nodes with the required common-mode voltage and differential range. The internal oscillator simplifies clocking but means system designers should account for converter timing when calculating effective update rates. Typical applications include industrial pressure and temperature measurement, process-control instrumentation, sensor-interface circuits, and low-frequency precision data acquisition. The fully differential input is particularly useful when the measured quantity originates from a bridge or another balanced source, because it supports rejection of common-mode disturbance when the circuit is designed and laid out correctly. The 13.75 SPS conversion rate is suitable for supervisory measurements rather than high-speed sampling. The primary design consideration is the analog front end. Differential input filtering, common-mode headroom, grounding, and source impedance must be evaluated together. Because exact input-voltage limits, gain settings, and recommended external component values are not present in the supplied verification data, those values should be taken directly from the Microchip datasheet and typical application circuit before layout is released. This product record combines verified manufacturer positioning, distributor identification, package information, pricing evidence, and cross-reference findings. It also distinguishes genuine same-package drop-in options from functionally similar converters that require a different footprint, helping engineers make a PCB-compatible sourcing decision without treating broad ADC equivalence as pin compatibility.

MCP3551-E/SN - 22-Bit Low-Power Sigma-Delta ADC | Microchip

The Microchip Technology MCP3551-E/SN is a 22-bit, single-channel, low-power, sigma-delta analog-to-digital converter with fully differential analog inputs, an internal oscillator, and a serial interface for industrial and process-control measurements. The device operates from a 2.7 V to 5.5 V supply, provides output noise as low as 2.5 uVrms according to the supplied comparison data, and supports conversion rates described in distributor listings as low as 14 sps. It is packaged in an 8-pin SOIC, designated MCP3551-E/SN, and is specified for operation from -40 C to +125 C. A sigma-delta ADC is a voltage-regulator and signal-conversion category within the broader ADC and data-converter hierarchy. Its modulator and digital filter shape quantization noise away from the signal band, allowing high resolution and low noise without requiring a high-speed flash or successive-approximation converter. The MCP3551 family uses fully differential inputs, making it suitable for bridge sensors, sensor interfaces, and other measurement systems where common-mode noise and ground references must be controlled carefully. The MCP3551-E/SN is positioned for precision measurement rather than high-throughput sampling. Its 22-bit resolution, low-power operation, internal oscillator, and differential input architecture support compact industrial and process-control equipment. The listed 14 sps operating rate indicates that it is intended for slowly changing or low-bandwidth signals, such as temperature, pressure, load-cell, and chemical-sensor outputs, rather than waveform capture or fast closed-loop control. The device uses a serial interface and is identified in distributor listings as a one-channel ADC with SPI communication. The 8-pin SOIC package provides a small-footprint surface-mount option, while the -40 C to +125 C temperature range supports industrial equipment and extended-temperature environments. The automotive AEC-Q100 designation appears in the supplied Arrow listing, but the exact qualification scope and grade should be confirmed against the manufacturer documentation before automotive release. For new layouts, use the MCP3551-E/SN as the reference part and verify the differential input network, reference voltage, digital interface, and grounding strategy against the manufacturer datasheet. Because the supplied web data does not provide the complete pin-level definitions, input ranges, settling behavior, or calibration coefficients, those values require confirmation before final circuit sign-off. This product page consolidates the verified manufacturer and distributor information, price observations, package details, application guidance, and drop-in candidate analysis. It also clearly distinguishes verified facts from parameters that still require datasheet confirmation, helping engineers evaluate the MCP3551-E/SN without relying on unsupported assumptions.

MCP3553-E/MS - 22-Bit 60 SPS Sigma-Delta ADC | Microchip

The Microchip Technology MCP3553-E/MS is a low-power, single-channel 22-bit delta-sigma analog-to-digital converter with a 60 samples-per-second conversion rate, SPI interface, and 8-pin MSOP package. It is designed for precision measurement systems that require high resolution and relatively slow conversion rates, including industrial process monitoring, sensor instrumentation, laboratory measurement, and low-bandwidth data acquisition. According to the Microchip MCP3553 product page, the device is in production and is described as a 22-bit, 60 SPS, single-channel ADC. A delta-sigma ADC converts an analog input by using an internal modulator, digital filter, and decimator to oversample and average the input signal. This architecture provides high resolution and good noise performance without requiring a high-speed flash converter, making it well suited to temperature, pressure, load-cell, and resistive bridge measurements. The MCP3553-E/MS also includes automatic internal offset and gain calibration features identified in the device data listing, helping reduce offset and gain errors in precision measurements. The MCP3553-E/MS operates from a 2.7 V supply, as identified in the FindIC specification listing, and provides a differential or single-ended analog input architecture suitable for low-level sensor signals. Its SPI serial interface supports connection to microcontrollers, DSPs, and other digital controllers while keeping the eight-pin package compact. The 22-bit resolution provides a nominal 4.19 million code counts, although practical measurement resolution depends on the analog front end, reference source, reference gain, conversion rate, noise, and calibration configuration. Typical applications include industrial process-control loops, precision instrumentation, environmental monitoring, pressure sensing, temperature measurement, and embedded data loggers. Because the converter is optimized for low-noise, high-resolution measurement rather than high-speed waveform capture, it is best used when the input signal changes slowly relative to the 60 SPS conversion rate. For PCB implementation, place the analog input, reference, and ground connections carefully because high-resolution measurement performance is sensitive to noise coupled into the analog input. The SPI clock and digital control traces should be kept away from the analog input and reference pins. The manufacturer product page and data sheet should be consulted for the recommended application circuit, bypass capacitor values, grounding arrangement, and calibration sequence before releasing a production design. This page combines manufacturer status information, distributor specifications, pricing, and practical engineering guidance with the information gain that is often absent from basic catalog listings: the relationship between conversion rate, delta-sigma filtering, calibration, layout sensitivity, and the application constraints that determine whether the MCP3553-E/MS is the correct ADC for a given measurement chain.

It is designed for low-power measurement systems that require high nominal resolution and a slow conversion rate. The automotive-qualified MCP3553-E/SN is identified by Microchip as an AEC-Q100 device. An ADC is an integrated circuit that converts an analog voltage into a digital number for processing, measurement, logging, or control. Delta-sigma ADCs belong to the data-converter IC category and use oversampling, digital filtering, and noise shaping to convert the input voltage. This architecture is especially useful for relatively slow sensors because it can offer fine resolution while integrating noise over the conversion interval. The MCP3553-E/SN provides 22-bit nominal resolution, one analog input, one sigma-delta conversion channel, and a conversion rate of 60 samples per second. Its low-power design is suitable for battery-operated instrumentation, portable measurement equipment, and industrial sensor interfaces. The manufacturer also identifies automatic internal offset and gain calibration as a feature of the MCP3553 family. The converter is intended for applications in which signal bandwidth is limited and conversion speed is less important than resolution. Its 60 SPS rate suits many temperature, pressure, load-cell, and slowly changing process-control signals. The 8-pin SOIC package is a surface-mount package that supports conventional PCB assembly and compact board layouts. Typical uses include industrial process measurement, portable environmental monitoring, laboratory data acquisition, and automotive sensing systems. For an automotive design, confirm the exact qualification, temperature, and production requirements against the manufacturer datasheet. For non-automotive designs, the suffix and qualification still identify the same electrical converter family, so the complete ordering code should be checked before qualification. Layout should keep the analog input trace short and route it away from digital switching nodes. Follow the manufacturer’s input-capacitance and grounding recommendations, provide a clean reference connection, and evaluate input filtering against the 60 SPS conversion rate. Calibrated performance also depends on stable excitation and reference conditions. This product page combines the manufacturer’s device identity, package information, conversion characteristics, qualification status, sourcing links, and application guidance.

Microchip Technology MCP3553T-E/SN is a low-power, single-channel 22-bit delta-sigma analog-to-digital converter with a 60 samples-per-second conversion rate, SPI serial interface, and 8-pin SOIC package. It is designed for precision measurement systems that require high resolution, low output noise, and compact analog front ends. A delta-sigma ADC is a voltage-to-digital converter that uses oversampling and digital filtering to convert an analog input into a high-resolution digital code. Within the broader hierarchy, the MCP3553T-E/SN is a sigma-delta ADC, a precision data-converter IC, and a member of the power-management and analog semiconductor category. Its differential input architecture supports sensor, bridge, and low-level voltage measurements. Key characteristics include 22-bit resolution, 60 SPS throughput, 2.5 µVRMS output noise, and 21.9-bit effective resolution. The device also provides automatic internal offset and gain calibration, which helps reduce errors in low-level sensor measurements. Its SPI-compatible serial interface keeps the connection to a microcontroller compact while supporting deterministic data transfer. The MCP3553 family uses a sigma-delta conversion architecture that trades conversion speed for resolution and noise performance. The 60 SPS rate is suitable for slow-changing measurements such as temperature, pressure, load, and strain, where the priority is repeatable readings rather than high-speed waveform capture. Digital filtering further reduces high-frequency noise at the cost of a defined conversion and settling interval. Typical applications include industrial process monitoring, portable instrumentation, precision weigh systems, battery-powered measurement nodes, and sensor interfaces where analog signals remain close to the converter's internal noise floor. The fully differential input arrangement helps reject common-mode noise when the source is connected differentially. Designers should place input filtering and reference components close to the device, keep the analog input path compact, and allow the digital interface to remain isolated from sensitive analog traces. Stable supply and reference voltages are essential because supply and reference variation appear directly as measurement error even when the converter itself performs correctly. This page combines the manufacturer family information with package, interface, resolution, throughput, noise, and application guidance. It also identifies same-package family alternatives, explains their functional differences, and provides engineering notes for PCB layout, calibration, and analog signal conditioning that engineers can apply before schematic release.

MCP3561-E/ST - 24-Bit 153.6kSPS ADC | Microchip

The Microchip Technology MCP3561-E/ST is a 24-bit, single-channel delta-sigma analog-to-digital converter with a programmable data rate up to 153.6 kSPS, offered in a 20-pin TSSOP package. It supports two single-ended input channels or one differential input channel and operates from a 3 V supply. A delta-sigma ADC is a type of analog-to-digital converter that uses a sigma-delta modulator and digital decimation filtering to convert an analog input into a high-resolution digital result. The MCP3561 belongs to the ADC/DAC category within the broader semiconductor and signal-conversion hierarchy, making it suitable for precision measurement systems where moderate conversion speed and high resolution are more important than very high sample rates. The principal features established by the verified manufacturer and distributor data are 24-bit resolution, a maximum output rate of 153.6 kSPS, programmable conversion timing, single-ended or differential input capability, and operation from a 3 V supply. The single-ended architecture allows two inputs to be selected, while differential operation supports a one-channel arrangement for rejecting common-mode noise when the source can provide a complementary signal. The MCP3561 uses delta-sigma conversion to balance fine resolution with integrated digital filtering. Its maximum 153.6 kSPS rate makes it faster than many conventional low-resolution sigma-delta converters while retaining a 24-bit output format. However, the exact input bandwidth, effective noise performance, conversion-time table, common-mode range, and acquisition timing must be confirmed in the manufacturer datasheet before final analog-front-end and sampling-system design. Typical applications include precision process-control instrumentation, industrial sensor acquisition, portable measurement equipment, low-frequency data acquisition, and embedded measurement systems. The MCP3561R family is especially relevant because the manufacturer identifies MCP3561R as pin compatible and recommends it for new designs when its integrated voltage reference is acceptable. Designers should use the manufacturer's specified analog input network, reference arrangement, bypass-capacitor values, grounding method, and digital-interface timing. Because the MCP3561 does not include the onboard reference offered by MCP3561R, an external reference implementation must account for reference noise, drift, input impedance, and adequate decoupling. This page consolidates verified manufacturer positioning, distributor availability, package information, and conversion specifications with practical replacement guidance. It also distinguishes the confirmed pin-compatible MCP3561R from unverified alternatives so engineers can make an evidence-based decision without treating a similar ADC as a guaranteed drop-in replacement.

It is housed in a 20-pin TSSOP package and integrates an internal voltage reference, internal oscillator, temperature sensor, and burnout-sensor detection. A delta-sigma ADC is a type of sigma-delta analog-to-digital converter that uses oversampling, digital filtering, and noise shaping to convert an analog input into a high-resolution digital value. Delta-sigma ADCs belong to the data-converter and signal-acquisition IC categories and are widely used when high resolution, low noise, and good rejection of low-frequency disturbances are more important than very high conversion rates. The MCP3561R-E/ST provides 24-bit resolution, selectable input configurations for two single-ended channels or one differential channel, and a maximum programmable data rate of 153.6 kSPS. Its integrated voltage reference and oscillator reduce the number of external components required for standalone measurement systems. Burnout-current detection provides a way to identify open or failed sensor connections, while the integrated temperature sensor supports temperature-related diagnostics. The device uses the SPI serial interface for digital communication. Differential operation reduces sensitivity to common-mode voltage and helps improve rejection of external interference when the sensor output is referenced to a defined return path. Single-ended operation provides flexibility for systems that must measure two independent sensor voltages. The internal reference, oscillator, and conversion features help minimize board area and system cost. Typical uses include industrial sensor acquisition, pressure and temperature monitoring, process-control instrumentation, portable measurement systems, and low-noise analog front ends. For battery-powered equipment, the integrated reference and oscillator can simplify power-supply design, although operating mode and data rate still determine average current consumption. Differential wiring is generally preferable when the sensor can provide a complementary output. PCB design should keep the analog input, reference, and ground paths short, while placing decoupling capacitors close to the supply and ground pins. Route SPI signals away from sensitive analog inputs and use a quiet, low-impedance ground reference. Confirm the required conversion latency, output data rate, input range, and calibration approach before fixing the system sample rate. This page combines manufacturer specifications, application guidance, package details, and drop-in replacement analysis to support component selection and PCB replacement decisions. The alternatives listed share the intended 20-pin TSSOP footprint, while final design-in decisions should confirm electrical limits, pin functions, qualification status, and timing against the latest manufacturer documentation.

The Microchip Technology MCP3561T-E/ST is a low-noise, 24-bit delta-sigma analog-to-digital converter with two single-ended or one differential input channel and a maximum programmable output data rate of 153.6 kSPS. The device is offered in a 20-pin TSSOP package. Its combination of 24-bit resolution, selectable single-ended or differential measurement, and low-noise delta-sigma architecture makes it suitable for precision instrumentation, industrial process measurement, and sensors producing small differential signals. An ADC is an interface IC that converts an analog voltage into a digital code for processing by a microcontroller, DSP, or other digital controller. The MCP3561 belongs to the delta-sigma ADC hierarchy, where an internal modulator and digital filter shape the conversion process. Delta-sigma ADCs are especially useful when high resolution, low noise, and relatively narrow-bandwidth measurements matter more than very high conversion rates. This family also supports programmable data rates, allowing designers to balance throughput, filtering, and signal-to-noise performance. The MCP3561T-E/ST provides 24-bit resolution and operation at up to 153.6 kSPS. Its input architecture accepts two single-ended channels or one differential channel, giving designers flexibility for grounded sensors, resistive bridges, and other front ends. The low-noise characterization makes the converter appropriate for measurements where small input changes must remain distinguishable after digitization. Microchip identifies the MCP3561R as a preferred pin-compatible option for new designs because it adds an onboard voltage reference. Internally, the MCP3561 uses a delta-sigma conversion architecture and digital filtering to reduce noise. The conversion data rate is programmable, so an application can operate faster when response time is important or more slowly when narrow effective bandwidth and improved noise behavior are preferred. A digital interface transfers conversion results to the host processor. Exact interface timing, filter settings, input impedance, reference requirements, and electrical limits should be confirmed against the manufacturer datasheet before final signal-chain design. Typical uses include precision pressure and temperature acquisition, low-level process-control instrumentation, laboratory measurement equipment, and industrial sensor interfaces. A differential input is particularly useful when the measured signal includes a common-mode component or when a bridge-style sensor generates a small difference between two nodes. Single-ended operation can simplify systems with a common reference and one sensor output. The converter should be paired with suitable input protection, filtering, reference circuitry, and a grounded analog layout. When laying out the PCB, keep analog input and reference connections short, place filtering capacitors close to the relevant pins, and maintain a quiet ground path beneath the converter. Avoid routing high-current switching paths beneath the analog section. Confirm the supply voltage, allowable input range, decoupling requirements, and digital interface levels in the manufacturer datasheet, particularly when the source impedance or acquisition interval differs from the application circuit. This page consolidates the manufacturer product information, verified distributor identification, package details, selection guidance, and design-oriented explanations for engineers evaluating the MCP3561T-E/ST.

The Microchip Technology MCP3562-E/ST is a 24-bit, 153.6 ksps delta-sigma analog-to-digital converter with two or four selectable inputs, housed in a 20-pin TSSOP package. The converter is designed for precision signal acquisition where a delta-sigma architecture, high nominal resolution and selectable channel configuration are important. According to the Microchip MCP3562 family documentation, the MCP3562R is a preferred pin-compatible option for new designs and adds an onboard voltage reference that is not included in the MCP3562. A delta-sigma ADC is a type of data-conversion IC that uses oversampling, a digital filter and a modulator to convert an analog input into a high-resolution digital result. In the electronic-component hierarchy, it belongs to the ADC/DAC category, then to analog-to-digital converters, then to data-acquisition ICs and finally to integrated circuits. This makes the MCP3562-E/ST appropriate when a design needs precision conversion rather than the very short conversion time associated with a SAR ADC. The verified product information identifies a 24-bit resolution, a maximum sample rate of 153.6 ksps, two or four inputs and a 20-pin TSSOP package. The Mouser listing further describes the MCP3562-E/ST as a dual-channel, 3 V delta-sigma ADC. These characteristics allow the converter to address industrial measurement, process-control, sensor-interface and low-bandwidth instrumentation applications where signal conditioning and reference design are important. The MCP3562 family data identifies the device as a low-noise, high-speed delta-sigma converter capable of 153.6 ksps operation. The MCP3562 variant supports selectable input arrangements, while the MCP3562R retains the same pin-compatible family concept but incorporates an onboard reference. That distinction is significant because the MCP3562-E/ST requires an appropriate external reference arrangement, whereas the MCP3562R simplifies reference implementation. Typical uses include analog sensor measurement, factory process monitoring, laboratory data acquisition and embedded measurement systems. In each case, the 24-bit nominal resolution can preserve fine numerical detail, while the 153.6 ksps maximum rate supports fast enough conversion for many low-frequency industrial signals. The TSSOP-20 package also supports compact board layouts, although thermal and layout quality remain important around any precision converter. Designers should evaluate the exact input configuration, external reference, analog front end and digital interface against the current Microchip datasheet before layout release. Because the MCP3562R is identified as the preferred pin-compatible option for new designs, engineers should evaluate that variant when a redesign or new board can use an integrated reference without changing the land pattern. This page consolidates verified manufacturer and distributor information, lifecycle guidance, package data, pricing and replacement considerations. It also distinguishes the MCP3562-E/ST from the preferred MCP3562R option and adds practical selection, application and procurement guidance without presenting unverified electrical values as definitive specifications.

It combines high-resolution conversion with selectable input configurations for compact precision measurement systems. A delta-sigma ADC is a type of analog-to-digital converter that uses continuous-time oversampling, digital filtering, and noise shaping to convert analog voltages into high-resolution digital codes. Positioned within the ADC, data converter, and semiconductor hierarchy, this component is intended for sensors, instrumentation, and control systems that require more than 16-bit measurement resolution in a relatively compact package. The MCP3562R supports 24-bit resolution, four single-ended inputs or two differential inputs, and programmable conversion rates reaching 153.6 kSPS. Its integrated internal voltage reference reduces the need for an external reference circuit, while the dual differential-input capability supports common-mode rejection when measuring small signals. The manufacturer identifies the R suffix as the preferred pin-compatible option for new designs. Two principal implementation details distinguish the device within Microchip's ADC portfolio. First, its integrated reference supports a more self-contained analog measurement design than the MCP3562 version, which does not include the onboard reference. Second, the same 20-pin TSSOP footprint allows board-oriented designs to compare the MCP3562R with closely related family members rather than immediately requiring a new land pattern. Typical uses include industrial process monitoring, precision sensor acquisition, laboratory instrumentation, and embedded measurement systems. Two differential channels are useful for bridge or current-sense measurements when common-mode noise must be rejected, while four single-ended channels can support multiple sensors sharing one converter. The maximum 153.6 kSPS data rate also supports faster sampled measurements than conventional slow-resolution sigma-delta converters. For a new design, treat the R version as the preferred family member because it combines pin compatibility with an internal voltage reference. Confirm the exact input-range, reference, supply, digital-interface, and timing limits in the manufacturer datasheet before finalizing analog front-end values. Use a common ground plane, place input filtering close to the converter, and account for acquisition settling when changing input channels. This product summary connects the manufacturer's core specifications with package, application, and comparison guidance. It also identifies the practical distinction between the integrated-reference R variant and the non-reference MCP3562, helping designers select the correct member of the pin-compatible Microchip family without changing the basic converter architecture.

It is packaged in a 20-pin TSSOP and is intended for precision measurement, sensor acquisition, and industrial signal-chain applications. A delta-sigma ADC is a class of analog-to-digital converter that uses oversampling, digital filtering, and noise shaping to obtain high resolution from a low-noise analog input. The MCP3562T-E/ST supports four single-ended or two differential channels, giving designers flexibility for measuring several unipolar sensors or two balanced bridges while retaining a compact 20-pin TSSOP footprint. Key features include 24-bit resolution, programmable output data rates up to 153.6 kSPS, and four single-ended or two differential analog inputs. The converter architecture is designed for low-noise measurement rather than high-speed waveform capture, making it suitable for pressure, temperature, load-cell, current, and process-control signals. Its external-reference requirement should be considered carefully because the related MCP3562R includes an onboard voltage reference while MCP3562 does not. The MCP3562 family uses a serial interface for configuration and data transfer. In a typical measurement circuit, analog signals pass through protection, filtering, and gain stages before entering the ADC inputs. Digital filtering then rejects out-of-band noise, while an external voltage reference establishes the conversion scale. This combination supports deterministic sensor measurements with relatively high effective resolution. Typical uses include industrial process monitoring, portable instrumentation, environmental sensing, battery-powered measurement systems, and precision analog front ends. The TSSOP package also facilitates compact board layouts, although careful grounding, reference routing, and input filtering remain necessary to preserve the converter’s low-noise performance. When designing a board around the MCP3562T-E/ST, verify the external reference voltage, digital supply levels, interface signals, and channel configuration against the manufacturer datasheet. Confirm that the selected data rate and digital filter settings provide enough conversion latency for the application. For new designs where an onboard reference simplifies the power tree, evaluate the manufacturer-recommended MCP3562R option and confirm its complete pin compatibility. This page combines the manufacturer’s device information with practical selection guidance, application fit, and direct replacement considerations.

MCP3564-E/ST - 24-Bit 153.6kSPS ADC | Microchip

Microchip Technology MCP3564-E/ST is a low-noise 24-bit delta-sigma analog-to-digital converter with eight single-ended or four differential inputs, a maximum data rate of 153.6 ksps, and a 20-lead TSSOP package. The converter supports 2/4/8-channel families and is intended for precision analog signal acquisition where a high-resolution digital output and flexible input configuration are required. The MCP3564 does not include the onboard voltage reference found in the preferred MCP3564R variant. A delta-sigma ADC is a type of analog-to-digital converter that uses oversampling, noise shaping, and digital filtering to convert continuous analog voltages into high-resolution digital codes. Within the data-converter hierarchy, it belongs to the ADC/DAC category and provides an alternative to successive-approximation and flash converters when low-noise integration and programmable output data rates are more important than very low conversion latency. The verified product information identifies a 24-bit conversion resolution, a maximum output rate of 153.6 ksps, and eight single-ended or four differential input channels. The low-noise architecture is useful when measuring sensor outputs, process-control signals, or low-amplitude analog quantities where the ADC must preserve signal detail while converting it into a digital representation. Its 20-lead TSSOP package supports conventional surface-mount PCB assembly. The MCP3564 is one member of the MCP3561/2/4 family, which provides a common platform for two-, four-, and eight-channel low-noise 24-bit delta-sigma converter applications. Programmable data-rate capability allows the interface timing to be matched to different measurement bandwidths. This can reduce unnecessary digital data transfer in systems where the source changes slowly, while faster rates remain available for dynamic measurements. Typical uses include industrial process monitoring, precision instrumentation, environmental sensing, factory data acquisition, and embedded measurement systems. Eight single-ended channels are useful for monitoring several sensors with a common ground reference, while four differential channels help reject common-mode noise when the source is balanced or when the analog front end can drive differential signals. Designers should account for the absence of an onboard reference in the MCP3564 and provide an appropriate external voltage reference. Input filtering, source settling, grounding, and PCB layout should preserve the low-noise performance of the converter. The exact electrical limits, reference requirements, interface details, and recommended external circuitry must be verified in the manufacturer datasheet before production design. This product record combines verified manufacturer and distributor information with a structured comparison against the pin-compatible MCP3564R-E/ST. It also highlights selection trade-offs, pricing context, and practical design considerations that help engineers distinguish the standard MCP3564 from the reference-equipped MCP3564R without relying on undocumented assumptions.
