AD7606BBCHIPS Overview
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.

Typical Applications
AD7606BBCHIPS is suitable for 6 applications: Power Line Monitoring, Protective Relays, Motor Control and Inverter Drives, Industrial Data Acquisition Modules, Medical Instrumentation, Test and Measurement Equipment.
Power Line Monitoring
The AD7606BBCHIPS fits power line monitoring because its eight simultaneous-sampling channels capture multiple phase voltages and currents with zero channel-to-channel skew, which is mandatory for correct active, reactive, and apparent power computation. The 800 kSPS per-channel rate supports harmonic analysis well beyond the 50th harmonic per IEC-class power quality requirements, and the 5 MOhm input impedance connects directly to transformer secondaries without loading the measurement. The integrated clamp protection tolerates switching transients on utility lines. Placed between the isolation front end and the DSP, it delivers digitized waveforms over SPI, with the on-chip antialiasing filter relaxing analog filter design at the front end.
Recommended
Protective Relays
Protective relays demand simultaneous sampling of three-phase voltage and current channels with deterministic timing, which the AD7606BBCHIPS provides through its eight per-channel SAR converters at up to 800 kSPS. The analog input clamp protection is a decisive advantage here, since relay front ends routinely face fault-induced transients and overvoltage conditions on CT and PT inputs. The bipolar input range on a single supply simplifies the isolated analog front end, and the on-chip PGA allows range scaling for both metering-grade accuracy and fault-recording dynamic range. According to the ADI datasheet, high input impedance yields under 20 LSB zero code with inputs grounded through 10 kOhm, keeping quiescent channel offsets low.
Recommended
Motor Control and Inverter Drives
In three-phase inverter and motor drive systems, the AD7606BBCHIPS digitizes DC bus voltage, three phase currents, and temperature feedbacks simultaneously, enabling field-oriented control algorithms that require aligned current samples. The 800 kSPS throughput per channel supports high PWM carrier frequencies, allowing overcurrent detection within a single switching period. Bipolar inputs accept bidirectional phase current signals from shunts or sensors directly on a single supply, and the integrated low-pass filter attenuates switching ripple ahead of conversion. The input clamp protection guards against dV/dt-induced transients common in power stages, improving robustness in electrically noisy drive environments.
Recommended
Industrial Data Acquisition Modules
Industrial DAQ modules benefit from the AD7606BBCHIPS integration: eight channels of clamp protection, PGA, filtering, and 16-bit SAR conversion in one device replace a discrete multiplexed front end, cutting board area and calibration effort. The 5 MOhm input impedance allows high-impedance sensors and voltage dividers to be connected without buffer amplifiers, and the single-supply bipolar input range removes the need for dual-rail analog supplies typical of older DAQ front ends. All channels convert simultaneously, so multi-sensor time correlation is preserved for vibration, pressure, and electrical measurements. Throughput of 800 kSPS per channel covers dynamic testing as well as slow process variables.
Recommended
Medical Instrumentation
Medical diagnostic equipment, including patient monitoring and physiological signal acquisition, uses the AD7606BBCHIPS to digitize multiple biopotential and pressure channels simultaneously at 16-bit resolution. The integrated antialiasing filter and PGA reduce external component count in front ends where board space and cleanliness matter, and single-supply operation simplifies isolation scheme design between the patient-connected side and system electronics. The high 5 MOhm input impedance minimizes loading of high-impedance electrode interfaces, protecting signal fidelity, while clamp protection adds a layer of robustness against defibrillation and electrostatic transient events in clinical environments.
Recommended
Test and Measurement Equipment
Bench and portable instruments, including multichannel oscilloscope front ends and automated test systems, leverage the AD7606BBCHIPS 800 kSPS simultaneous sampling and 16-bit resolution for accurate waveform capture across eight channels. The on-chip digital filter with programmable bandwidth lets instruments adapt noise filtering to the measurement band without changing hardware. Bipolar inputs accept AC-coupled and DC-coupled signals directly, and input clamp protection improves survivability against user-connected overrange signals, a common field failure in test gear. The parallel/serial interface flexibly mates with FPGA or MCU-based acquisition engines at full throughput.

Key Differentiators
- 5 MOhm input impedance eliminates external driver amplifiers (vs AD7606BSTZ)
- 4x faster throughput in the same footprint (vs AD7606BSTZ)
- Lower cost than highest-accuracy family member (vs AD7606C-16BSTZ)
Design Notes
Do not treat the AD7606BBCHIPS as identical to the original AD7606BSTZ. According to ADI application note AN-1559, the AD7606B generation is a drop-in upgrade with hardware-mode differences that must be reviewed during migration, including register and configuration differences. The input impedance also differs (5 MOhm vs 1 MOhm), which changes divider loading behavior in existing front ends. Always re-verify the software configuration and input network when substituting between generations.
The 5 MOhm input impedance allows direct connection to high-impedance sources, but PCB leakage currents can still corrupt low-level signals. Guard the analog input traces, use clean flux removal under the ADC, and keep input traces short and shielded with ground pour. The datasheet notes that with inputs pulled to ground through only a 10 kOhm resistor, zero code error stays below 20 LSB - degraded layout hygiene can easily exceed this figure in production boards.
Decouple the analog supply and reference with low-ESR ceramic capacitors placed as close to the pins as possible, and follow the datasheet power-up sequencing between the analog and digital supply rails. Because the part integrates the PGA and antialiasing filter, reference noise directly affects all eight channels' SNR; a precision low-noise reference with adequate decoupling preserves the 16-bit performance at the full 800 kSPS throughput.
