AD7606TSTZ-EP - 16-Bit 8-Channel Simultaneous Sampling DAS | Analog Devices
MPN： AD7606TSTZ-EP ✓ 啟用中AD7606TSTZ-EP 概覽
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.

典型應用
AD7606TSTZ-EP 適用於 6 應用s: Power Line Monitoring and Protective Relays, Industrial Multi-Channel Control and Motor Monitoring, Aerospace and Defense Data Acquisition, Medical Imaging and Patient Monitoring Front Ends, Automatic Test Equipment (ATE) and Instrumentation, Renewable Energy Inverters and Solar Monitoring.
Power Line Monitoring and Protective Relays
The AD7606TSTZ-EP is a leading choice for power-line monitoring and protective relay designs because its 8 simultaneous sampling channels digitize three-phase voltages and currents at the same instant, a hard requirement for phasor computation and relay trip algorithms. The ±10 V and ±5 V true bipolar input ranges accept conditioned VT/CT signals directly, while the 1 Mohm constant input impedance and integrated 23 kHz antialiasing filter remove the need for external driver op amps and second-order filter stages. The 150 kSPS per-channel rate is far above power-cycle sampling requirements, and the pin-driven digital filter lets designers oversample to raise SNR for metering-accuracy channels on the same PCB used for protection channels.

Industrial Multi-Channel Control and Motor Monitoring
In industrial control cabinets, the AD7606TSTZ-EP consolidates eight analog sensor inputs - current shunts, position potentiometers, pressure and temperature bridges scaled to bipolar levels - into one 16-bit converter. The single-supply architecture (no external bipolar rails) reduces power supply count in dense I/O modules, and the integrated clamp protection tolerates input overvoltage transients common on factory floors. The SPI/QSPI/parallel interfaces connect cleanly to standard PLC processors, and the -55C to +125C EP rating also covers cold-store and foundry ambients that exceed commercial limits. The flexible digital filter allows low-speed, high-SNR settings for DC-type sensors without changing sampling hardware.

Aerospace and Defense Data Acquisition
The -EP suffix targets exactly this domain: per the Analog Devices product page, the AD7606-EP supports defense and aerospace applications under the AQEC standard with a -55C to +125C military temperature range, controlled manufacturing baseline, single assembly/test site, single fabrication site, product change notification, and qualification data available on request. Avionics flight-test instrumentation and telemetry systems use its 8 simultaneous channels to sample vibration, strain, and pressure transducers with timestamp-consistent sampling. The 64-LQFP package supports standard inspection flows, and the integrated 2.5 V reference simplifies BOM control for programs that require long-term configuration traceability.

Medical Imaging and Patient Monitoring Front Ends
Multi-channel patient monitoring and diagnostic equipment benefits from the AD7606TSTZ-EP's simultaneous sampling: ECG, respiration, and pressure channels must be sampled in phase for accurate waveform correlation. The ±5 V range, 1 Mohm input impedance, and on-chip antialiasing filter let a single device acquire multiple conditioned physiological channels without external op amps, reducing board area in portable monitors. The 16-bit resolution and oversampling digital filter deliver the effective-noise floor needed for low-amplitude biosignals, while the clamp protection adds robustness against defibrillator-style transient events reaching the acquisition front end.
推薦
Automatic Test Equipment (ATE) and Instrumentation
Bench instruments and rack ATE modules use the AD7606TSTZ-EP as a compact multi-channel digitizer front end. The 150 kSPS per-channel throughput, 16-bit SAR linearity, and pin-selectable digital filter cover a wide range of test signals from DC calibration levels to 20 kHz-class dynamic signals (filter 3 dB cutoff 23 kHz). Both parallel and serial (SPI/QSPI/MICROWIRE) interfaces allow the same converter to serve fast parallel bus backplanes or pin-limited serial modules. The wide -55C to +125C range also suits rack equipment placed near thermal loads, and tray packaging supports production integration.
推薦
Renewable Energy Inverters and Solar Monitoring
Solar string inverters and grid-tie converters require simultaneous capture of DC bus, AC output voltages, and currents for MPPT, anti-islanding, and grid-code compliance. The AD7606TSTZ-EP's 8 channels cover three-phase sensing plus DC monitoring in one device; ±10 V bipolar inputs accept isolated-amplifier outputs directly. Its 16-bit resolution supports power-quality measurements (harmonics, unbalance), and the 23 kHz antialiasing filter plus oversampling filter reject switching-frequency noise from the inverter bridge. The extended temperature range suits outdoor NEMA enclosures that reach well beyond commercial limits in summer installations.

主要差異化特點
- Military temperature range and AQEC traceability (對比AD7606TSTZ)
- Two extra simultaneous channels for the same footprint (對比AD7606-6TSTZ)
- Integrated signal chain eliminates external conditioning (對比AD7606BSTZ)
設計說明
The AD7606TSTZ-EP runs on a single analog supply with no external bipolar rails required, thanks to its on-chip input clamp, filtering, and 1 Mohm constant input impedance. Decouple VDRIVE and analog supplies with 100 nF ceramics placed within 2 mm of each supply pin, plus a 10 uF bulk capacitor. The integrated 2.5 V reference removes the external reference BOM item, but if the design requires metering-class accuracy, evaluate an external precision reference instead of the internal reference path, with the reference buffer configured accordingly.
Use the pin-driven digital filter deliberately: it trades 3 dB bandwidth for SNR. For fast transient capture set the minimum filter; for DC-type channels (temperature, bus voltage) select higher oversampling to raise effective resolution toward 16-bit noise-free levels. The 23 kHz antialiasing filter attenuates broadband noise before sampling, but any clock harmonic from an adjacent switching converter that folds below 23 kHz will pass - keep switch-node traces away from the analog inputs and route the bipolar input traces as short, matched pairs.
Do not substitute the commercial AD7606TSTZ or AD7606BSTZ in designs specified for the EP part: the -EP variant carries the -55C to +125C military range and AQEC-standard traceability (single fab, single assembly/test site, product change notification) that commercial parts do not, which can fail defense/aerospace program audits. Additionally, the AD7606-6 and AD7606-4 share the LQFP-64 footprint but expose fewer channels - verify your firmware channel map before assuming a footprint-only swap is functionally complete.
