AD7610BSTZ-RL - 16-Bit 250kSPS PulSAR ADC | Analog Devices
MPN: AD7610BSTZ-RL ✓ Hoạt độngAD7610BSTZ-RL Tóm tắt
A SAR ADC is a type of analog-to-digital converter that uses a binary search algorithm to convert an analog input into a digital output. It employs a comparator and a successive approximation register to iteratively narrow down the input voltage range, achieving high resolution and speed with low power consumption. SAR ADCs are widely used in data acquisition systems, industrial process control, and medical instrumentation where high accuracy and moderate sampling rates are required.
Key features of the AD7610 include 16-bit resolution with no missing codes, a maximum throughput of 250 kSPS, and multiple programmable input ranges. The device offers a high-speed parallel interface and a serial SPI-compatible interface, providing flexibility in system integration. It also includes an internal reference buffer and supports external references, enabling precise voltage scaling. The iCMOS process ensures high voltage handling and low noise performance.
The AD7610 architecture uses charge redistribution, which provides inherent sample-and-hold functionality and excellent linearity. The device includes a track-and-hold amplifier that captures the input signal, followed by a capacitive DAC that performs the successive approximation. This design achieves a typical signal-to-noise ratio (SNR) of 89 dB and a total harmonic distortion (THD) of -107 dB, making it suitable for high-precision measurement applications.
Typical applications include industrial process control, data acquisition systems, medical instrumentation, and automated test equipment. The programmable input ranges allow direct interface with sensors and transducers without external scaling circuitry, simplifying design and reducing component count. The high input impedance and low power consumption make it ideal for battery-powered portable instruments.
When designing with the AD7610, ensure that the analog input is properly buffered and that the reference voltage is stable and low-noise. The device requires a clean power supply with adequate decoupling to achieve optimal performance. The serial interface can be used to configure the input range and power-down modes, reducing power consumption in battery-operated systems.

Ứng dụng tiêu biểu
AD7610BSTZ-RL phù hợp cho 6 Áp dụngs: 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.

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.

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.

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.

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.

Ghi chú thiết kế
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.
