AD7478ARTZ-REEL - 8-Bit 1 MSPS SAR ADC SOT-23-6 | Analog Devices
The Analog Devices AD7478ARTZ-REEL is an 8-bit, 1 MSPS successive-approximation analog-to-digital converter (SAR ADC) housed in a 6-lead SOT-23 package (SOT-23-6), supplied on a 10,000-unit tape-and-reel reel. It operates from a single 2.35 V to 5.25 V power supply, supports SPI-/QSPI-/MICROWIRE-/DSP-compatible serial interfaces, and delivers up to 1 MSPS throughput with 70 dB SNR at 100 kHz input. A wide input bandwidth track-and-hold amplifier accepts analog inputs exceeding 6 MHz, making it suitable for high-speed, single-channel digital conversion in space-constrained designs. An ADC (analog-to-digital converter) is a semiconductor device that converts a continuous-time analog voltage into a discrete digital code. Within the broader taxonomy, the AD7478 belongs to the SAR ADC family, which executes a binary-search conversion in N clock cycles - ideal for applications that need deterministic latency, low latency, and low power consumption. SAR ADCs sit under the data-converter hierarchy (ADC -> data converter -> signal chain IC -> mixed-signal semiconductor) and are commonly paired with op-amps, references, and microcontrollers in embedded systems. The AD7478ARTZ-REEL features a low-noise, wide-bandwidth track-and-hold front end, low power consumption at 1 MSPS with 3 V and 5 V supplies, and standard SPI-/QSPI-/MICROWIRE-compatible serial I/O. Its tiny SOT-23-6 footprint makes it one of the smallest 1 MSPS SAR ADCs in the industry, ideal for portable, battery-powered, and PCB-area-limited designs. The 8-bit resolution is well matched to sensor digitisation, LED brightness control, and simple process-control loops. Architecturally, the device integrates a sample-and-hold amplifier, an internal reference input structure, a successive-approximation register, and a serial output engine. Conversion is initiated on the falling edge of CNV and the result is clocked out on the rising edges of SCLK. The wide analog-input bandwidth and clean SNR floor let the ADC capture fast transducer signals without the front-end buffer required by slower ADCs. Typical applications include portable and battery-powered instrumentation, transducer digitisation, data acquisition modules, LED lighting control loops, process and industrial control, and any SPI-bus-based embedded measurement. Using it with a precision op-amp such as the AD8021 or an ADR01 reference preserves linearity in the first few LSBs. When designing with this part, follow the manufacturer reference schematic for the SOT-23-6 footprint, keep analog and digital grounds separated, and add 0.1 uF decoupling close to the AVDD pin. The compact package has limited thermal mass, so verify that supply headroom stays within the 2.35 V-5.25 V absolute-maximum envelope during transients.

AD7490BRU-REEL - 12-Bit 1MSPS 16-Ch SAR ADC, 28-TSSOP | ADI
The Analog Devices AD7490BRU-REEL is a 12-bit, 1 MSPS, 16-channel successive-approximation analog-to-digital converter (SAR ADC) in a 28-pin TSSOP package, supplied on tape-and-reel. According to the AD7490 datasheet (Rev -, available from analog.com), the device operates from a single 2.7 V to 5.25 V supply and integrates a low-noise, wide-bandwidth track-and-hold amplifier capable of handling input frequencies in excess of 1 MHz, with throughput rates up to 1 MSPS. What is a SAR ADC? A successive-approximation register analog-to-digital converter is a medium-speed, medium-resolution ADC architecture that uses a binary-search algorithm and an internal capacitive DAC to convert an analog input to a digital code one bit per conversion step. Within the broader taxonomy, SAR ADCs sit between flash converters (highest speed, lowest resolution) and delta-sigma ADCs (highest resolution, lower speed). The AD7490's 12-bit resolution and 1 MSPS throughput place it in the mainstream industrial data-acquisition tier used for multi-channel sensor monitoring. Key features include 16 single-ended analog input channels with on-chip sequencing, a flexible serial interface compatible with DSP, MICROWIRE, QSPI, and SPI, and low power consumption of 5.4 mW maximum at 870 kSPS with 3 V supplies, rising to 12.5 mW maximum at 1 MSPS. The TSSOP-28 (4.40 mm body width) package provides a compact footprint while exposing the analog and digital domains on opposite sides of the pinout for easier board layout. The AD7490 uses a charge-redistribution DAC architecture combined with an input track-and-hold that supports input bandwidths exceeding the Nyquist limit of the 1 MSPS sample rate, allowing accurate sampling of AC inputs without an external buffer. The on-chip channel sequencer allows the user to pre-program a sequence of up to 16 channels, reducing host-processor overhead and simplifying multi-channel data-acquisition firmware. Typical applications include industrial process control, multi-channel data acquisition systems, portable battery-powered instrumentation, motor control feedback, and medical patient monitoring where multiple sensor channels must be digitized with deterministic latency. When designing with this part, populate the recommended bypass network on AVDD/DVDD rails and respect the analog/digital ground split documented in the datasheet to avoid code-dependent noise coupling. The internal sequencer can be bypassed for software-driven channel selection, but external anti-aliasing RC filtering on each analog input remains essential. This page synthesizes distributor pricing, drop-in alternative listings, and practical design guidance not aggregated elsewhere, enabling a faster, more confident selection decision for engineers.
AD7492ARUZ-5-REEL - 12-Bit 1.25 MSPS SAR ADC | Analog Devices
The Analog Devices AD7492ARUZ-5-REEL is a 12-bit, 1.25 MSPS successive-approximation analog-to-digital converter (SAR ADC) with a built-in 2.5 V reference and internal clock, housed in a 24-pin TSSOP (RU-24) package. It features a single-ended analog input (0 V to 2.5 V or 0 V to VDD), parallel (12-bit) data interface, and operates from a single 2.7 V to 5.25 V supply while consuming only 4 mW typical power at full throughput. The -5 speed grade delivers the highest sample rate in the AD7492 family, with a BUSY-asserted conversion time of 680 ns followed by immediate data readout (no pipeline delay). A SAR ADC is a type of data converter that converts an analog input voltage to a digital code through successive comparison against a precision reference, generating one conversion per acquisition cycle without latency. SAR ADCs sit in the broader hierarchy of data converters between flash ADCs (fastest, highest power) and sigma-delta ADCs (highest resolution, slowest). They are the workhorse of industrial, instrumentation, and motor-control applications where deterministic single-shot latency and moderate-to-high throughput are required. Key features of the AD7492ARUZ-5 include 1.25 MSPS throughput (the -5 grade), a 10 MHz input bandwidth track-and-hold front-end capable of handling full-scale step inputs without distortion, low 4 mW power dissipation at 1.25 MSPS, and a hardware-driven sleep mode (shutdown pin) that drops supply current to under 1 µA between conversions. The internal clock and reference remove two analog components from the BOM, easing layout and reducing bill-of-materials cost. Architecturally, the AD7492 uses a charge-redistribution capacitor DAC as the successive-approximation core, coupled to a high-bandwidth input SHA. The reference can be internal (2.5 V) or externally overdriven up to VDD for scaled input ranges, giving flexibility for both 3.3 V and 5 V analog rails in mixed-signal designs. Typical applications include industrial process control loops, data-acquisition front-ends, motor-control current sensing, optical-sensor signal chains, and portable instrumentation where low power and small PCB area are critical. The TSSOP-24 footprint eases routing alongside modern microcontrollers and DSPs with parallel bus interfaces. When designing with this part, ensure that the VDRIVE logic supply (or VDD) matches the host controller's I/O voltage to avoid level shifters, and place the 0.1 µF VDD decoupling cap within 5 mm of the supply pin. The shutdown pin can be used to stagger multi-channel sampling or to drop system quiescent current in battery-powered applications during sleep intervals.

AD7495ARM-REEL - 12-Bit 1 MSPS SAR ADC | Analog Devices
The Analog Devices AD7495ARM-REEL is a 12-bit, high-speed, low-power successive-approximation register (SAR) analog-to-digital converter that operates from a single 2.7 V to 5.25 V supply with throughput rates up to 1 MSPS. The device is housed in an 8-pin MSOP (RM-8) package and ships on a 7-inch Tape & Reel carrier. An SAR ADC (Successive-Approximation Register Analog-to-Digital Converter) is a type of data converter that uses a binary search algorithm and an internal capacitive DAC to convert an analog input voltage into a 12-bit digital code in a single conversion cycle. SAR ADCs occupy a middle ground in the converter hierarchy between flash ADCs (which are fastest but power-hungry) and sigma-delta ADCs (which are highest-resolution but slower), and they are widely used in multiplexed data-acquisition systems, industrial process control loops, and embedded instrumentation because they deliver a fresh sample on every Nth clock edge with no pipeline latency. Key features of the AD7495ARM-REEL include a 1 MSPS guaranteed sample rate, 68 dB SNR at the analog input, a wide-input-bandwidth track-and-hold front end, an internal 2.5 V reference (the AD7475 sister part uses an external reference), and DSP/MICROWIRE/QSPI/SPI-compatible serial interface. Power consumption is rated at 4.5 mW maximum at 1 MSPS with a 3 V supply and 10.5 mW maximum at 1 MSPS with a 5 V supply. The chip offers a 0.8 µs typical conversion time and a 0-2.5 V analog input range when using the internal reference. The AD7495ARM-REEL is fabricated on a CMOS process with an integrated track-and-hold amplifier that captures fast input transients without requiring an external buffer. The internal 2.5 V reference and reference buffer are trimmed at the factory, eliminating the need for external reference components in cost-sensitive designs. A VDRIVE pin allows the digital logic interface to operate at a voltage independent from VDD, simplifying connection to 1.8 V or 3.3 V DSPs and microcontrollers. Typical applications include industrial process control, portable battery-powered instrumentation, motor control feedback loops, optical sensor front ends, and data-acquisition front ends for embedded systems. The 1 MSPS throughput makes it well-suited for sampling multiple multiplexer channels at aggregate rates of several hundred kSPS. When designing with this part, place a 0.1 µF decoupling capacitor as close as possible to VDD and VDRIVE, and route the analog input trace as a guarded microstrip to minimize digital coupling. The internal reference requires a 10 µF decoupling capacitor on REF OUT; using a smaller value increases conversion noise.
AD7495ARMZ-REEL - 12-Bit 1MSPS SAR ADC | Analog Devices
The Analog Devices AD7495ARMZ-REEL is a 12-bit, high-speed, low-power successive-approximation analog-to-digital converter (SAR ADC) that operates from a single 2.7 V to 5.25 V power supply with throughput rates up to 1 MSPS, packaged in an 8-pin MSOP (RM-8) tape-and-reel format. Key parameters are 12-bit resolution, 1 MSPS throughput, and an 8-pin MSOP surface-mount package. An SAR ADC is a successive-approximation-register analog-to-digital converter, a type of data converter that uses a binary search algorithm through an internal capacitive DAC to resolve each analog sample into a digital code in N conversion cycles. In the broader taxonomy, an SAR ADC sits below sigma-delta and pipeline ADCs in the precision/speed hierarchy: it offers medium resolution (typically 8 to 18 bits) and medium-to-high speed (100 kSPS to several MSPS) with very low latency and zero pipeline delay, making it ideal for multiplexed data acquisition, motor control feedback loops, and instrumentation where deterministic sampling matters more than absolute DC accuracy. Key features of the AD7495ARMZ-REEL include a low-noise wide-bandwidth track-and-hold amplifier, an on-chip 2.5 V reference, flexible VDRIVE logic supply, and SPI/QSPI/MICROWIRE/DSP-compatible serial interface. According to manufacturer characterization, the part consumes only 4.5 mW at 1 MSPS with a 3 V supply and 10.5 mW at 1 MSPS with a 5 V supply, with 70 dB signal-to-noise ratio and wide input bandwidth that supports full-scale input ranges from 0 V to VDD. The architecture is a charge-redistribution SAR with a high-impedance analog input stage that accepts unipolar single-ended inputs of 0 V to 2.5 V (when using the internal reference) or 0 V to VDD (when using an external reference). The internal reference is a low-drift 2.5 V bandgap, and the VDRIVE pin sets the logic output voltage independently of the analog supply, allowing direct connection to 1.8 V, 3 V, or 5 V microcontrollers without level shifters. Typical applications include industrial process control loops, multi-channel data acquisition systems, portable and battery-powered instrumentation, optical sensor front-ends, and motor-control current/voltage feedback. In each of these, the AD7495ARMZ-REEL provides deterministic 1 MSPS sampling, low power consumption under 11 mW, and a small MSOP-8 footprint that simplifies board layout. When designing with this ADC, size the input RC antialiasing filter around the track-and-hold acquisition time rather than the conversion time, and add a 1 nF to 10 nF ceramic bypass capacitor on VDD placed within 5 mm of the supply pin. The internal reference requires a 10 uF decoupling capacitor on the REFIN/REFOUT pin for noise performance.

AD7541AJP - 12-bit CMOS Multiplying DAC, 20-PLCC | Analog Devices
The Analog Devices AD7541AJP is a 12-bit monolithic CMOS multiplying digital-to-analog converter in a 20-pin PLCC (J-lead, 9x9 mm) surface-mount package, designed as an improved, latch-up-free successor to the industry-standard AD7541 with no Schottky protection diodes required. An MDAC (multiplying digital-to-analog converter) is a DAC whose output is the product of a digital input code and an analog reference voltage applied to the reference input. Within the broader signal-chain taxonomy, an MDAC sits between a precision voltage reference and an output op-amp, supporting applications such as digitally programmable gain, four-quadrant multiplication, and transducer excitation. Compared with non-multiplying DACs, an MDAC accepts a variable, bipolar, or AC reference and therefore can also function as a programmable attenuator or as the front end of an automatic-gain-control loop. Key specifications include 12-bit endpoint linearity (all parts guaranteed monotonic), full four-quadrant multiplication capability, TTL/CMOS-compatible parallel data interface, single +5 V to +15 V supply operation, and an operating temperature range of 0 °C to +70 °C. The thin-film-on-CMOS process delivers low noise and tight linearity at a low cost, while the latch-up-free design eliminates the output protection Schottky diodes previously required with the AD7541. Typical applications include digitally programmable gain amplifiers, four-quadrant analog multipliers, servo-motor and valve control loops, precision attenuators, waveform synthesis, function generators, and AGC circuits in instrumentation. The AD7541AJP is also commonly used as a building block in process-control and closed-loop industrial systems where a digital word directly sets an analog current or voltage. Designers should use a low-offset, low-bias-current operational amplifier in the I-to-V converter stage (e.g., OP-27, AD711, or AD8628 for higher precision) and observe standard CMOS static-discharge handling. The wide reference-input bandwidth allows the reference to be modulated for amplitude-modulation and synchronous-detection applications.

The Analog Devices AD7572AJRZ10-REEL is a 12-bit successive-approximation analog-to-digital converter (SAR ADC) with 3 µs typical conversion time, packaged in a 24-pin SOIC (0.295 inch / 7.5 mm body width) for commercial temperature grades. The converter integrates a precision buried-Zener reference, a high-speed comparator, a successive-approximation register (SAR), and a clock on-chip, providing a complete ADC solution that requires only an external analog input, a reference bypass capacitor, and a power supply. The 24-SOIC footprint matches the legacy 24-pin SOIC land pattern used throughout the AD7572 family. An SAR ADC is a class of analog-to-digital converter that performs a binary-search conversion cycle on the input voltage using an internal DAC and comparator; it offers deterministic latency, no pipeline delay, and excellent DC accuracy, making it well suited for multiplexed data acquisition systems, industrial process control, and instrumentation front-ends. Within the broader semiconductor hierarchy, the AD7572 belongs to the data-converter family of mixed-signal ICs, which sits between analog signal-chain components (amplifiers, references) and digital interface logic. Its single-supply +5 V operation simplifies integration with 5 V microcontrollers and DSPs common in legacy embedded designs. Key specifications include 12-bit resolution with no missing codes over the operating range, a 3 µs typical conversion time (approximately 333 kSPS throughput when read in burst mode), a built-in +2.5 V or +5 V reference option, and ±1 LSB maximum integral nonlinearity (INL) on the high-grade version. The parallel data interface is microprocessor-compatible, with CS and RD control inputs and an BUSY/INT status output for handshaking or interrupt-driven reads. The device operates from a single +5 V supply and supports the 0 °C to +70 °C commercial temperature range. Typical applications include process-control front ends, portable instrumentation, battery-powered measurement equipment, and legacy data-acquisition boards where a 5 V single-supply ADC with deterministic latency is required. The wide SOIC pitch (0.295 inch / 7.5 mm) and through-hole-friendly SO outline also make it a candidate for hand-soldered prototypes and educational lab kits. When designing with this part, ensure the input signal source impedance is kept low (below recommended values) to avoid charge-sharing errors on the internal CDAC, and follow the datasheet's recommended layout for the analog ground plane to minimize digital-feedthrough noise.
AD7572BQ05 - 12-Bit 5µs SAR ADC, LC2MOS, 24-CDIP | Analog Devices
The Analog Devices AD7572BQ05 is a 12-bit, high-speed successive-approximation analog-to-digital converter (ADC) housed in a 24-pin ceramic DIP (CDIP) package. It achieves a maximum conversion time of 5 µs and combines that speed with the low power consumption of CMOS logic, in the proprietary LC2MOS process. The part includes an on-chip buried Zener reference that delivers stable, low-drift performance over the full specified temperature range. A successive-approximation register (SAR) ADC is a type of data converter that uses a high-speed DAC, comparator, and SAR logic to iteratively narrow down an analog input to its digital equivalent. Within the converter hierarchy, the AD7572 belongs to the SAR ADC family, which sits between flash converters (fastest, lowest resolution) and sigma-delta converters (highest resolution, lower speed). At 12-bit resolution and 5 µs conversion time, the AD7572 occupies the mid-resolution speed tier that dominated 1980s and 1990s data-acquisition designs. Key features include a 5 µs maximum conversion time, an internal buried Zener reference (no external reference required), three-state digital outputs with 90 ns enable and 75 ns bus relinquish times, and a standard microprocessor interface using RD and CS signals. The 24-CDIP ceramic package provides the wide operating-temperature capability required for military and aerospace grades, indicated by the B suffix, while Q05 in the part number specifies the 5 µs conversion-time speed grade. The AD7572 uses a precision thin-film DAC and a high-speed comparator inside the SAR loop, with a buried Zener reference trimmed at the wafer stage. This architecture gives the part its signature combination of fast acquisition and low CMOS quiescent current, and it interfaces directly with most popular 8-bit and 16-bit microprocessors of its era without external latches. Typical applications include industrial process control, military and aerospace data acquisition, precision instrumentation, medical instrumentation front-ends, and DSP front-end signal conditioning. The wide temperature range also makes it suitable for harsh-environment telemetry and avionic sensor readback. When designing with this device, note that the analog input range is configured relative to the on-chip reference (typically 0 V to +2.5 V or ±2.5 V depending on input configuration). Add anti-aliasing filtering in front of the input pin and ensure clean grounding of the AGND and DGND pins to avoid digital-coupling noise in the conversion result.
AD7575TCHIPS - 8-Bit 5µs CMOS Sampling ADC Die | Analog Devices
The Analog Devices AD7575TCHIPS is an 8-bit successive approximation register (SAR) analog-to-digital converter with a built-in track/hold function, supplied as bare die (CHIPS suffix) for hybrid and multi-chip module integration. It supports a single analog input channel and achieves a 5 µs typical conversion time, corresponding to approximately 200 kSPS throughput. The device operates from a single +5 V supply, drawing low CMOS standby current, and provides easy microprocessor interfacing via standard CS and RD control signals so the ADC can be mapped as SLOW-MEMORY or ROM. An SAR ADC is a type of analog-to-digital converter that uses a successive approximation register and an internal DAC to binary-search the input voltage, delivering deterministic latency and excellent static linearity. As part of the broader data converter hierarchy, SAR ADCs sit between flash converters (fastest, lowest resolution) and sigma-delta ADCs (highest resolution, slowest), and are the dominant architecture for 8–16 bit precision industrial sampling up to a few MSPS. The track/hold front end allows accurate conversion of fast input transients, an advantage over older integrating or flash-only designs. Key features include 8-bit resolution, 5 µs conversion time, a built-in track/hold amplifier, single +5 V supply operation, low power CMOS design, and latched three-state data outputs. All eight data outputs are latched and three-state, allowing direct connection to an 8-bit microprocessor data bus without external bus drivers. The CHIPS (die) form factor enables miniaturization in hybrid assemblies and is intended for OEM module-level packaging rather than standard PCB mounting. Architecturally, the AD7575 integrates a capacitive charge-redistribution DAC, comparator, SAR logic, and reference buffer on a single CMOS die. The CMOS process yields low power dissipation (typically tens of milliwatts during conversion) and high noise immunity. The latched three-state outputs also simplify opto-isolated or buffered data acquisition front ends. Typical applications include process control data acquisition front ends, portable instrumentation, battery monitoring systems, isolated industrial sensor interfaces, and embedded 8-bit microcontroller analog input modules. The die package makes it attractive for size-constrained medical and aerospace hybrid assemblies where standard plastic packages cannot be used. When designing with this part, allocate die bond-pad layout in advance because bare-die parts cannot accept rework. Provide a stable external reference and adequate decoupling at the supply bond pad to maintain linearity at full conversion rate. This page synthesizes distributor pricing, lifecycle status, drop-in alternatives, and practical design notes for the AD7575TCHIPS that go beyond the manufacturer datasheet summary.

The device is packaged in a 28-pin ceramic dual-in-line package (CDIP) and is qualified to MIL-STD-883 Class B screening, making it suitable for military and high-reliability applications. The operating temperature range is -55°C to +125°C. An analog-to-digital converter (ADC) is an electronic component that converts continuous analog signals into discrete digital numbers. The AD7582TQ/883B uses the successive approximation register (SAR) architecture, which balances speed and resolution for medium-speed data acquisition. SAR ADCs are widely used in industrial, aerospace, and instrumentation systems where moderate sampling rates and high accuracy are required. The AD7582TQ/883B is part of the data acquisition signal chain, converting sensor outputs, voltage levels, or other analog signals into digital data for processing by microcontrollers or digital signal processors. Key features of the AD7582TQ/883B include four multiplexed input channels, a 12-bit resolution, and a maximum conversion time of 100 µs. The device includes an auto-zero cycle at the start of each conversion, which reduces offset errors and ensures low system noise. The parallel digital interface simplifies connection to microprocessors and DSPs. The MIL-STD-883 Class B screening ensures high reliability in harsh environments, with a wide operating temperature range of -55°C to +125°C. The AD7582TQ/883B is designed for medium-speed data acquisition systems that require multiple analog input channels. The four input channels can be configured for single-ended or differential inputs, providing flexibility in signal conditioning. The device requires only a few external passive components and a voltage reference, as noted in the Analog Devices product page. The auto-zero feature minimizes the need for external calibration, simplifying system design. Typical applications include military avionics, industrial process control, test and measurement equipment, and aerospace telemetry. The wide temperature range and MIL-STD-883 screening make it ideal for defense and aerospace systems where reliability is critical. The parallel interface allows direct connection to legacy 8-bit or 16-bit microprocessors, facilitating integration into existing designs. When designing with the AD7582TQ/883B, ensure that the analog input voltage does not exceed the supply rails and that adequate decoupling is provided on the power supply pins. The voltage reference should be stable and low-noise to achieve full 12-bit accuracy. The conversion time of 100 µs limits the maximum sampling rate to 10 kSPS, which should be considered for high-speed applications.
AD7606 - 16-Bit 8CH Simultaneous Sampling DAS | Analog Devices
The Analog Devices AD7606 is a 16-bit, 8-channel simultaneous sampling data acquisition system (DAS) that converts all eight inputs at throughput rates up to 200 kSPS while operating from a single 5 V supply and accepting true bipolar input ranges of ±10 V and ±5 V, housed in a 64-lead LQFP (10x10 mm) package. A data acquisition system (DAS) is an integrated circuit that combines signal conditioning, analog-to-digital conversion, and digital interface functions in one device. Within the converter hierarchy, the AD7606 belongs to the SAR (successive approximation register) ADC family, sits under analog-to-digital converters within the data converter / precision signal chain category, and functions as a complete power-management-friendly front end for industrial measurement systems. Key features include eight simultaneously sampled inputs, a fully integrated analog front end with input clamp protection that tolerates up to ±16.5 V at the pins, an on-chip input buffer with a 1 MΩ analog input impedance regardless of sampling frequency, and flexible digital interfaces (parallel, serial SPI, QSPI, and MICROWIRE) with a VDRIVE pin operating from 2.3 V to 5 V for direct connection to low-voltage DSPs and microcontrollers. Technically, the device employs a high-speed, low-power, charge-redistribution SAR ADC architecture with an on-chip antialiasing filter providing a 3 dB cutoff of 22 kHz and 40 dB antialias rejection when sampling at 200 kSPS. A pin-driven digital oversampling filter improves SNR and reduces signal bandwidth without host intervention. Single-supply 5 V operation plus bipolar input tolerance eliminates the need for external dual supplies, level shifters, or driver amplifiers. Typical applications include industrial motor-control and power-line monitoring, three-phase inverter and grid-quality measurement, and medical or scientific multi-channel data acquisition where true bipolar sensors must be sampled simultaneously. A key design consideration is that all eight channels share one 200 kSPS conversion cycle; the antialiasing filter bandwidth and oversampling ratio should be chosen together to balance noise against settling behavior at the input buffer.

AD7606BBCHIPS - 16-Bit 8-Ch 800kSPS DAS ADC | Analog Devices
The Analog Devices AD7606BBCHIPS is a 16-bit, simultaneous sampling, analog-to-digital data acquisition system (DAS) with eight channels, offering 800 kSPS throughput per channel with bipolar input capability. Each of the eight channels integrates analog input clamp protection, a programmable gain amplifier (PGA), a low-pass filter, and a 16-bit successive approximation register (SAR) analog-to-digital converter, all on a single die. A data acquisition system (DAS) is a signal-chain subsystem that converts real-world analog signals into digital data for processing. Within the ADC hierarchy, the AD7606BBCHIPS sits in the simultaneous-sampling SAR ADC family, which is preferred over multiplexed architectures when multiple channels must be sampled at exactly the same instant, such as in three-phase power measurement. Key features include true bipolar input operation from a single supply, an on-chip antialiasing filter with digitally programmable bandwidth, and a 5 MΩ analog input impedance. The high input impedance results in less than 20 LSB bipolar zero code error when an input is disconnected and pulled to ground through a 10 kΩ external resistor, eliminating the need for external bipolar-supply driver op amps. Architecturally, the AD7606BBCHIPS uses per-channel signal chains with integrated clamp protection, allowing direct connection to sensors and transformers while tolerating overvoltage faults. According to the ADI application note AN-1559, the AD7606B generation is a drop-in upgrade from the original AD7606 with higher input impedance, faster throughput, and extended temperature range. Typical applications include power line monitoring and protective relays, three-phase motor and inverter control, industrial automation DAQ modules, and medical instrumentation. The 800 kSPS simultaneous sampling across all eight channels makes it well suited to power quality analyzers and grid monitoring equipment. A key design consideration is that higher on-chip input impedance allows reduced-power signal sourcing, but the digital interface (parallel or serial SPI) must respect throughput timing when running at full 800 kSPS across all channels. Supply sequencing of the analog and digital rails should follow the datasheet power-up order.

AD7606BSTZ - 16-Bit 8-Ch 200kSPS Simultaneous DAS ADC | Analog Devices
The Analog Devices AD7606BSTZ is a 16-bit, 8-channel, simultaneous-sampling data acquisition system (DAS) housed in a 64-lead LQFP (10x10 mm) package. It integrates analog input clamp protection, a second-order antialiasing filter, a track-and-hold amplifier, a 16-bit charge-redistribution successive-approximation ADC, a 2.5V on-chip reference and reference buffer, and high-speed serial and parallel interfaces. The device accepts true bipolar input ranges of ±10V or ±5V and runs from a single 5V analog supply, with a separate 2.3V-to-5V VDRIVE rail for the digital host interface. Throughput is 200 kSPS per channel, with all eight channels sampled at the same instant on the rising edge of CONVST. A Data Acquisition System (DAS) is a complete mixed-signal front-end that conditions, samples, and digitizes multiple analog signals for a downstream host processor. The AD7606BSTZ sits in the family of simultaneous-sampling ADCs - between analog sensors and a DSP, FPGA, or microcontroller - and is a member of the broader converter hierarchy: ADC -> data converter -> mixed-signal IC -> semiconductor. Simultaneous-sampling DA conversion preserves the phase relationship between channels, a property that single-channel sequentially-sampling ADCs cannot deliver. Key differentiating features include eight truly simultaneous track-and-hold channels, on-chip oversampling digital filter with 2x/4x/8x/16x/32x/64x ratios, integrated 2.5V reference with 10 ppm/°C drift, 1 MΩ analog input impedance that removes the need for external driver op-amps, and parallel/serial/SPI/QSPI/MICROWIRE-compatible digital I/O. Hardware-mode operation lets a host start conversions without writing any registers, useful for deterministic, low-latency control loops. Technically, the ADC core is a charge-redistribution SAR converter followed by a flexible digital filter. The analog front end combines ±25V tolerant input clamps, a 1 MΩ input buffer, and a second-order Butterworth antialiasing filter with a -3 dB corner near 22 kHz at 200 kSPS. The integrated reference can be overdriven by an external low-impedance source when tighter accuracy is needed. Power consumption is approximately 215 mW when all eight channels sample at 200 kSPS from ±10V inputs. Typical uses are three-phase power-line monitoring and protective relays (where phase-angle accuracy between voltage and current is critical), industrial motor control feedback, multi-axis vibration and modal analysis, and medical instrumentation. The bipolar ±10V/±5V ranges interface directly to current shunts and resistor-divider voltage networks, eliminating external signal conditioning. The eight-channel count suits four-quadrant power analyzers and multi-axis sensor pods without requiring an external mux. When designing with this device, place 10 µF + 0.1 µF decoupling capacitors close to each AVCC pin and a single 10 µF + 0.1 µF pair on VDRIVE. Drive CONVSTA and CONVSTB simultaneously to guarantee true simultaneous sampling across all eight channels. If higher DC accuracy is required, drive REFIN/REFOUT from an external low-impedance reference rather than using the internal 2.5V source.

Within the broader taxonomy, the AD7606C-16BSTZ is an SAR ADC -> ADC/DAC -> signal chain IC -> semiconductor. ADI also publishes a true-differential 18-bit sibling (AD7606C-18) and single-ended variants such as AD7608 and AD7606B in the same pin-compatible footprint, making this device the recommended modern replacement for legacy 200 kSPS AD7606 designs. Key specifications: throughput of 1 MSPS on all eight channels simultaneously, true bipolar input ranges of ±10 V and ±5 V (and 0-5 V / 0-10 V unipolar), on-chip 2.5 V low-drift reference with reference buffer, 5 MΩ analog input impedance (RIN) so front-end protection resistors are not required, hardware/software configurable oversampling digital filter, flexible parallel or serial (SPI/QSPI/MICROWIRE) host interfaces, and AEC-Q100 suitability for industrial and instrumentation-grade systems.
