Typical Applications
AD7610BSTZ-RL is suitable for 6 applications: Industrial Process Control, Data Acquisition Systems, Medical Instrumentation, Automated Test Equipment, Battery-Powered Portable Instruments, Precision Measurement and Metrology.
Industrial Process Control
The AD7610BSTZ-RL's programmable ±10 V, ±5 V, 10 V, and 5 V input ranges allow direct connection to PLC analog input cards and 4-20 mA loops without external scaling resistors. Its 16-bit resolution at 250 kSPS captures fast-moving transducer signals, while the 89 dB SNR preserves measurement fidelity in noisy factory environments. For best performance, pair the ADC with precision in-amps like AD620ARZ for sensor conditioning and a REF192ESZ reference; an STM32F446VCT6 MCU handles SPI configuration and data logging.
Recommended
Data Acquisition Systems
In high-speed data acquisition, the AD7610 provides deterministic SAR conversion without pipeline delay, enabling accurate multiplexing across multiple analog input channels. The parallel interface supports high-throughput transfers to an FPGA or MCU, while the SPI port reduces pin count in compact designs. With 16-bit no-missing-codes performance and 250 kSPS speed, the ADC can oversample slower signals to improve effective resolution. Use AD7176-2BRUZ as a companion high-performance ADC for additional channels when system density is required.
Recommended
Medical Instrumentation
Medical monitoring and diagnostic equipment require low-noise, high-resolution data conversion with predictable timing. The AD7610's 89 dB SNR and -107 dB THD help preserve small biological signals after front-end amplification, while its 250 kSPS rate supports real-time waveform acquisition. The wide programmable input range simplifies direct connection to pre-conditioned biopotential and physiological sensor outputs. Pair with low-offset op-amps such as AD8629ARZ and the AD8221ARZ to maintain microvolt-level accuracy.
Recommended
Automated Test Equipment
ATE systems demand fast, repeatable, and accurate digitization of many different signal types. The AD7610 supports multiple programmable input ranges, reducing the need for relay-switched attenuators when testing devices with different output levels. The high-speed parallel interface allows waveform captures at 250 kSPS with minimal FPGA resource usage. Its 16-bit linearity and 89 dB SNR provide the accuracy needed for production test limits across ±10 V, ±5 V, 10 V, and 5 V ranges.
Recommended
Battery-Powered Portable Instruments
Portable instruments benefit from the AD7610's low power dissipation of 115 mW at 250 kSPS and its flexible 2.3 V to 5.25 V digital supply, which allows direct connection to low-voltage MCUs. The programmable power-down modes available through the serial configuration port reduce average current in duty-cycled measurement applications. This makes the AD7610 suitable for field meters, portable data loggers, and handheld diagnostic tools where both accuracy and battery life are critical.
Recommended
Precision Measurement and Metrology
For laboratory-grade measurement, the AD7610's 89 dB SNR, -107 dB THD, and 16-bit no-missing-codes specification provide a reliable core for precision voltmeters, calibrators, and metrology systems. The internal reference buffer simplifies the reference source and maintains stability when driving the ADC's switched-capacitor input. Combining the AD7610 with a low-noise amplifier such as AD8221ARZ and a stable reference like REF192ESZ maximizes achievable system accuracy.

Key Differentiators
- Four field-selectable input ranges without external scaling (vs ADS8509IBDB)
- Lower power at 250 kSPS compared to higher-speed family siblings (vs AD7612BSTZ)
- Single-channel 48-lead LQFP package (vs AD7606BSTZ-RL)
Design Notes
Provide a clean 5 V analog supply to the AVDD pin and a separate 2.3 V to 5.25 V digital interface supply for the host I/O voltage. Bypass each supply with a 100 nF ceramic capacitor placed as close as possible to the pin, plus a larger 10 µF bulk capacitor per supply. The reference input should also be decoupled with a low-ESR capacitor; a noisy reference directly degrades the 89 dB SNR specification.
Use a solid ground plane below the ADC and keep analog input traces short and shielded from digital switching signals. Route the SPI or parallel digital lines away from the analog input and reference traces to minimize coupling. For the capacitive SAR input, add a low-pass RC filter or a high-speed op-amp buffer at the analog input to reduce charge-injection kickback and maintain linearity.
Verify the programmable input range is configured correctly through pins or SPI before the first conversion. Applying an input beyond the selected range can saturate the converter and may violate absolute maximum ratings. Confirm the digital interface supply voltage is present and within the 2.3 V to 5.25 V range before serial communication begins, otherwise configuration writes can be lost.
For 16-bit performance, the reference source impedance should be low so that the internal reference buffer is not starved during conversion. Place the reference decoupling capacitor within 5 mm of the REF pin. If a high-speed SAR ADC like the AD7612 is selected instead, plan for a faster settling driver and tighter layout because 750 kSPS throughput requires a wider analog input bandwidth.
Compliance Information
No compliance statements were included in the provided web data. The AD7610 is an industrial ADC; verify RoHS/REACH and lead-free status from the latest Analog Devices datasheet or distributor product page before finalizing BOM.
