MCP3562-E/ST - 24-Bit Dual-Channel Delta-Sigma ADC | Microchip
Référence : MCP3562-E/ST ✗ Fin de vieMCP3562-E/ST Présentation
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.

Applications typiques
MCP3562-E/ST convient pour 6 applications: Industrial Process Sensor Measurement, Precision Pressure and Level Instrumentation, Laboratory and Portable Data Acquisition, Condition Monitoring and Environmental Sensors, Power and Energy Metering, Embedded Data Acquisition and Control.
Industrial Process Sensor Measurement
The MCP3562-E/ST fits industrial process measurement when the application requires more numerical resolution than a conventional 16-bit converter but does not need SAR-class conversion speed. Its 24-bit nominal resolution and 153.6 ksps maximum sample rate provide a suitable balance for temperature, pressure, level and other slowly changing analog process signals. The device would normally follow an instrumentation amplifier, filter and protection network, with an external reference appropriate to the MCP3562 configuration. The principal design consideration is preserving sensor accuracy through the complete analog chain; the ADC cannot recover resolution lost in the front end. Because exact input range and SNR are not included in the supplied verified data, engineers must confirm them in the manufacturer datasheet before selecting resistor values, protection devices and filtering.
Recommandé
Precision Pressure and Level Instrumentation
The MCP3562-E/ST is appropriate for precision pressure or level instrumentation because its 24-bit delta-sigma resolution can represent small analog changes across a restricted measurement span. The maximum 153.6 ksps rate is more than adequate for common process variables that change over seconds or minutes, while the 20-pin TSSOP package supports compact analog and digital board layouts. The converter should be fed from a low-noise reference because the MCP3562 does not include the onboard reference found in the MCP3562R. A practical signal chain needs excitation, bridge or ratiometric conditioning, an anti-alias filter and careful grounding. Verify the allowed common-mode and differential input ranges in the Microchip family datasheet, especially when the sensor is grounded, floating or connected to hazardous equipment.
Recommandé
Laboratory and Portable Data Acquisition
The MCP3562-E/ST can serve as the conversion element in a laboratory or portable data-acquisition instrument when high nominal resolution and compact packaging are priorities. Its 153.6 ksps maximum conversion rate supports acquisition of many low-frequency transducer signals, and the serial output can reduce the number of data lines required on a compact board. A complete instrument still needs a low-noise analog front end, channel multiplexing or selection, clock and reference strategy, plus a host interface capable of receiving the converter data. The integrated-reference advantage of the MCP3562R may simplify a new design, but the MCP3562-E/ST can be retained when an existing board already has a proven reference network. Validate digital timing, settling behavior and filter configuration against the current manufacturer datasheet.
Recommandé
Condition Monitoring and Environmental Sensors
The MCP3562-E/ST can be used in condition-monitoring equipment for vibration, temperature, humidity or other environmental transducers when fine resolution and repeatable low-frequency sampling are important. The 24-bit delta-sigma architecture is well matched to sensors whose useful bandwidth is much lower than the ADC's 153.6 ksps maximum rate. Designers should place suitable anti-alias filtering ahead of the converter and keep the analog path away from switching supplies and digital clocks. The MCP3562 requires an external reference arrangement, making reference stability and grounding central to measurement quality; the MCP3562R can simplify a new design by adding an onboard voltage reference. Before qualification, confirm noise density, input settling, common-mode range and operating-temperature limits from the manufacturer documentation.
Recommandé
Power and Energy Metering
The MCP3562-E/ST is applicable to energy-metering front ends that digitize comparatively slow voltage or current-derived signals after appropriate scaling. Its 24-bit nominal resolution can preserve detail in small measurement increments, while the 153.6 ksps maximum rate provides timing margin for synchronized sampling and post-processing. A real energy-meter implementation also requires anti-alias filters, isolated sensing elements, gain calibration and low-drift references. The lack of an onboard reference in the MCP3562 may be acceptable when the design already uses an accurately trimmed external reference, but the MCP3562R can reduce external circuitry for new designs. Neither device should be selected solely from headline resolution; the manufacturer datasheet must confirm input bandwidth, common-mode limits and effective noise performance for the selected gain and conversion mode.
Recommandé
Embedded Data Acquisition and Control
The MCP3562-E/ST is suitable for embedded control boards that must acquire precision analog sensor data and present it to a microcontroller or digital controller. The serial interface can limit pin demand, and the 20-pin TSSOP package is convenient for compact mixed-signal layouts. The system should allocate separate, quiet analog and digital return paths and place input filtering close to the converter pins. External-reference quality remains important because the MCP3562 lacks the onboard reference included in the MCP3562R. For a new platform, compare that integration advantage; for an established platform, changing the ADC can invalidate calibration, gain, settling-time and safety records. Verify the exact digital protocol and timing in the current Microchip documentation before assigning firmware tasks.

- Higher stated SNR than the MCP3561T comparison result (vs MCP3561T-E/ST)
Notes de conception
Keep the analog input traces short, shielded from digital switching paths and surrounded by a quiet ground reference. Place the anti-alias filter close to the ADC input so that cable and board leakage do not add appreciable error. Separate noisy switching-regulator paths from the converter and avoid routing serial data directly beneath sensitive analog inputs. The supplied excerpts do not provide the manufacturer's recommended layout values, so component values and trace geometry must be taken from the current family datasheet.
Treat reference accuracy and supply noise as part of the ADC error budget rather than separate concerns. The MCP3562 does not include the onboard voltage reference offered by the MCP3562R, so an existing MCP3562 board must use a suitable external reference. Check reference temperature drift, noise and load behavior against the converter requirements. Decoupling and layout guidance should follow the manufacturer datasheet because no verified capacitor values or voltage tolerances were included in the supplied data.
Do not assume that the headline 24-bit resolution is equivalent to 24 useful bits in every operating mode. Resolution depends on gain, input source impedance, reference quality, filtering, conversion speed and system noise. The MCP3561-family alternatives provide only 16-bit nominal resolution and therefore cannot preserve the same numerical range. Similarly, the MCP3562R's integrated reference simplifies circuitry but does not prove identical accuracy in every calibration or application configuration.
