AD7606C-16BSTZ

AD7606C-16BSTZ - 16-bit 8-ch 1MSPS Bipolar DAS ADC | ADI

The Analog Devices AD7606C-16BSTZ is a 16-bit, simultaneous-sampling, 8-channel data acquisition system (DAS) with 1 MSPS per-channel throughput, packaged in a 64-pin LQFP (10x10 mm) with an exposed pad. Each channel integrates analog input clamp protection, a programmable gain amplifier (PGA), a low-pass anti-alias filter, and a 16-bit successive-approximation-register (SAR) ADC, all operating from a single 5 V analog supply. A data acquisition system (DAS) is an integrated subsystem that combines multiple ADC channels with input signal conditioning, references, and interfaces so an embedded MCU, DSP, or FPGA can digitize many analog sensors simultaneously. 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. Design considerations: at 1 MSPS with eight channels streaming, the digital interface bus activity is heavy, so keep the LQFP exposed pad soldered to a continuous ground pour for thermal dissipation and to lower digital return impedance. For best THD and SNR, drive AVDD/REF_CAP from low-noise regulators (e.g., LT3042 / LT3045) and decouple VDRIVE independently from the 5 V AVCC rail so digital transients do not couple into the analog front end. Typical applications include three-phase power-line monitoring, multi-axis industrial motor control, simultaneous data acquisition front ends, instrumentation and test equipment, and medical multi-channel patient monitoring. According to the ADI datasheet, the AD7606C-16 family is recommended by ADI for new designs over the legacy AD7606, and the LQFP-64 footprint is shared so firmware/PCB migration is trivial.

AD7606C-18BSTZ

AD7606C-18BSTZ - 18-Bit 8-Ch 1MSPS DAS ADC | Analog Devices

The Analog Devices AD7606C-18BSTZ is an 18-bit, 8-channel, simultaneous-sampling data acquisition system (DAS) based on successive-approximation-register (SAR) ADC architecture, sampling at up to 1 MSPS per channel and housed in a 64-pin LQFP (10 mm x 10 mm) package. The device integrates analog input clamp protection, a programmable gain amplifier (PGA), a low-pass analog input filter, and an 18-bit SAR ADC per channel, delivering true bipolar input ranges of ±10 V, ±5 V, and 0 V to 10 V from a single 5 V analog supply. A 2.5 V on-chip low-drift precision reference and a reference buffer are included, eliminating the need for external reference components in most designs. A simultaneous-sampling SAR ADC is a category of precision data converter that captures the instantaneous voltage on all input channels at the same instant under one common convert-start signal, then performs a binary-search quantization in successive bit decisions per channel. The AD7606C-18 sits inside the hierarchy: SAR ADC -> data acquisition system (DAS) -> precision ADC -> analog-to-digital converter -> mixed-signal IC. Synchronous multi-channel acquisition is essential when phase relationships between signals must be preserved. Key features include an on-chip digital filter with oversampling ratios from 2x to 256x, integrated analog input clamps with ±16.5 V tolerance, a per-channel PGA with hardware gain settings of 1, 2, 4, 8, 16, 32, and 64, and both parallel and serial (SPI-/QSPI-/MICROWIRE-/DSP-compatible) host interfaces. Throughput remains 1 MSPS per channel across all eight channels simultaneously, with SNR of approximately 91 dB and THD near -100 dB at the maximum sampling rate. The 5 V single-supply operation simplifies system power design versus traditional ±15 V industrial front ends. The architecture pairs a high-impedance input front end (typically 1 MΩ) with a charge-redistribution SAR core, controlled by an internal precision reference and a flexible sequencer. Hardware overrange detection and per-channel sequencer flags accelerate FPGA-/DSP-side post-processing. An extended operating temperature range of -40 °C to +85 °C supports industrial deployment, and the part is rated to withstand ±16.5 V analog overvoltages on every input without damage. Typical applications include three-phase power-line monitoring and protection relays, multi-axis industrial motor control, patient monitoring ECG/EEG front ends, vibration and structural-health data loggers, and high-channel-count data acquisition modules. The combination of true bipolar inputs, simultaneous sampling, integrated analog front end, and on-chip reference makes the AD7606C-18 a single-chip replacement for legacy multi-component discrete DAS front ends. When designing with the AD7606C-18, allocate the LQFP-64 land pattern with thermal copper pour tied to the exposed pad (EP) for lowest junction-to-ambient resistance, and use 100 nF plus 10 µF decoupling on AVDD/AVDD_DR with 100 nF plus 10 µF on VDRIVE close to the device. Drive CONVST with a clean low-jitter source; jitter couples directly to the SNR budget. For best DC accuracy, allow the on-chip reference a 5 ms settling after power-up.

A data acquisition system (DAS) is a specialized analog-to-digital converter subsystem that combines signal conditioning, sampling, and conversion in one integrated circuit. Within the hierarchy of signal chain components, a DAS sits above a plain ADC: it adds input protection, filtering, and channel sequencing so a processor can digitize multiple bipolar sensors through a single device without external op amps or bipolar supplies. Key features include a 1 MΩ analog input impedance that is constant regardless of sampling frequency, single-supply operation (5 V analog, 3.3 V or 5 V digital) that eliminates driver op amps and external bipolar rails, and an antialiasing filter with a 3 dB cutoff of 23 kHz. The pin-driven digital filter improves SNR and reduces 3 dB bandwidth on demand. Interfaces include SPI, QSPI, MICROWIRE, and parallel/serial modes. As an ADI Enhanced Product (EP), the AD7606TSTZ-EP supports defense and aerospace applications under the ADI AQEC standard, with a military temperature range of -55C to +125C, a controlled manufacturing baseline, one assembly/test site, one fabrication site, product change notification, and qualification data available on request (per Analog Devices AD7606-EP product page and datasheet). Typical applications include power-line monitoring and protective relays in grid infrastructure, multi-channel industrial control and motor monitoring, and aerospace/defense instrumentation where extended temperature range and controlled manufacturing are mandatory. Design consideration: the on-chip 2.5 V reference and reference buffer remove the need for an external precision reference in most designs, but for best noise performance at 16-bit resolution, decouple the reference buffer closely and allow the digital filter to trade bandwidth for SNR.

The simultaneous sampling capability is essential for accurate phase measurement and multi-axis synchronization. The 18-bit resolution enables detection of small signal variations that 16-bit systems miss. When designing with the AD7608, place decoupling capacitors close to the AVCC and DVCC pins, and route the reference decoupling capacitor adjacent to REFIN/REFOUT. Balance the oversampling ratio against settling time so the increased digital filtering does not reduce the effective throughput below system requirements.

SAR ADCs sit at the next level of the converter hierarchy below delta-sigma and pipelined ADCs and are valued for their deterministic latency, single-shot accuracy, and lack of pipeline delay, which makes them well suited to multiplexed channel scanning, control loops, and event-driven sampling. The PulSAR family is Analog Devices' registered name for its precision, charge-redistribution SAR converter line. Key differentiating features include three selectable throughput modes (3 MSPS in wideband warp and warp modes, 2 MSPS in normal mode, and 1.25 MSPS in impulse mode), a 2.048 V internal reference, both serial and parallel (16- or 8-bit bus) digital interfaces, and a flexible input span driven by an external differential driver or AD8021/AD8138 driver. The warp mode and wideband warp mode further accelerate throughput by allowing faster acquisition at the cost of a tightened aperture window. Architecturally, the device pairs a high-bandwidth differential input track-and-hold with a precision charge-redistribution capacitive DAC and an on-chip conversion clock, which simplifies board-level timing. The single 2.5 V supply simplifies power-tree design, and the exposed-pad LFCSP-VQ package provides a low-thermal-resistance path to the PCB copper for heat spreading during continuous 3 MSPS operation. Typical application areas include medical imaging front-ends, industrial process control and data acquisition, instrumentation and automatic test equipment (ATE), and high-speed multichannel multiplexed systems. The 3 MSPS throughput and ±2 LSB INL are well aligned to imaging signal chains and to per-channel scanning modules behind a multiplexer. When designing in this ADC, allocate adequate ground and reference decoupling close to the pins, and lay out the analog input traces as a true differential pair terminated at the driver outputs. Use a low-jitter, low-phase-noise sampling clock to preserve aperture accuracy, and follow the AD7621 evaluation board layout for the LFCSP-VQ exposed pad to keep junction temperature within the rated -40 °C to +85 °C operating range.

The Analog Devices AD7651ASTZRL is a 16-bit, 100 kSPS successive approximation register (SAR) analog-to-digital converter with integrated reference, packaged in a 48-pin LQFP (7 mm × 7 mm) and shipped on tape and reel. As a member of the PulSAR unipolar ADC family, it combines charge-redistribution SAR architecture with a wide ±10 V or 0–5 V true bipolar/unipolar input range through Analog Devices' iCMOS high-voltage process technology. The integrated 2.5 V reference, low noise floor, and 100 kSPS throughput make it a strong fit for industrial data acquisition and process control front-ends. A successive approximation register ADC is a precision data converter that resolves one bit per conversion cycle using an internal DAC and comparator; SAR ADCs deliver deterministic latency, no-pipeline-delay sampling, and inherently low noise because quantization noise is not folded into the baseband. The SAR architecture sits within the data-converter hierarchy of analog-to-digital converters -> ADCs -> precision ADCs -> successive approximation ADCs -> industrial ADCs, and the integrated reference places this part in the power management-adjacent category of self-contained analog front-ends. Key features of the AD7651ASTZRL include 16-bit resolution with no missing codes, 100 kSPS throughput, an integrated low-drift reference, both serial and parallel interface options, and a wide input voltage range supporting true bipolar ±10 V or unipolar 0 V to 5 V operation directly from ±12 V or +5 V supplies. The device also provides flexible power management through per-channel logic, hardware gain compression at PGA=2, and low power consumption of 8 mW typical at 100 kSPS. Typical applications include industrial process control and PLC analog input modules, multi-channel data acquisition systems, portable or battery-powered instrumentation, and power-line monitoring where ±10 V signals must be digitized directly. The wide input range eliminates the need for front-end signal conditioning in many 4–20 mA or ±10 V transducer scenarios. When designing with this device, ensure the AVCC and DVDD rails are properly decoupled with 10 uF tantalum and 100 nF ceramic capacitors as recommended in the manufacturer datasheet, and verify that the REF decoupling (10 uF/100 nF) is placed close to the REF pin to preserve linearity at full throughput.
