ADS8331IRGER

ADS8331IRGER is a 16‑bit analog-to-digital converter (ADC) from Analog Devices. It uses a successive-approximation register (SAR) architecture and provides a serial SPI‑compatible digital output, making it suitable for precision data acquisition and instrumentation.
Key points:
- 16‑bit resolution with low noise and power, designed for single‑supply operation.
- SPI-compatible interface for easy integration with microcontrollers and processors.
- Intended for precision sensing and measurement in instrumentation, industrial control, and portable systems.
IRGER suffix notes:
- Industrial temperature range, RoHS/lead‑free compliant, and tape‑and‑reel packaging.
For exact electrical specs (input range, reference options, timing, throughput, and pinout), consult the ADS8331IRGER datasheet. This will tell you the appropriate reference configuration, sampling rate, and how to connect your signals to meet your accuracy and speed requirements.

Direct cross-reference for ADS8331IRGER isn’t published. Equivalents are other 16-bit, 8-channel, SPI delta-sigma ADCs at ~250 ksps. Likely substitutes:
- Analog Devices: AD7696, AD7689
- Linear Technology: LTC2380-16
- TI: ADS8316 / ADS832x family
Confirm with datasheets and use a distributor cross-reference for pinout and timing.

- Pin count: 16 pins
- Function: 16-bit analog-to-digital converter (ADC) with an SPI-compatible serial interface. It accepts analog input on AIN+ (and AIN− for differential mode), converts it, and outputs the result on DOUT with CS, SCLK, and DIN/DOUT pins. Includes power and ground pins (AVDD, DVDD, AGND, DGND), reference pins (REFIN/REF OUT or VREF), and digital control pins (CONVST and RESET/SHDN or PDWN). The IRGER variant denotes the 16-pin package for this device.

- Manufacturer: Texas Instruments Incorporated (TI).
- What kind of company: An American multinational technology company that designs and manufactures semiconductors and integrated circuits, including analog, digital, and embedded processing products.

ADS8331IRGER is a 16‑bit, 250 ksps, low‑power ADC with a serial interface (SPI-compatible). Key application areas include:
