概述

Description

The ADS8331IRGER is a Texas Instruments 16-bit, low-power successive-approximation ADC with a SPI-compatible serial interface. It converts an analog input to a 16-bit digital word and outputs via a serial data stream. The IRGER suffix indicates an industrial-temperature, RoHS-compliant 8-pin package. It’s designed for compact, MCU-friendly data acquisition in instrumentation, sensors, and embedded control systems, offering a good balance of resolution, speed, and power for many applications. For exact electrical specs (supply range, input range, maximum sampling rate, and power), refer to the official datasheet for this specific package and operating mode.

Features

Key features of ADS8331IRGER (industrial temp, RoHS):
- 8-channel multiplexed analog input
- 12-bit successive-approximation ADC
- SPI-compatible serial interface (SCLK, CS, DIN/DOUT)
- On-chip sample-and-hold
- Flexible reference: internal reference option plus external reference input
- Wide supply range: 2.7 V to 5.25 V
- Throughput up to about 1 MSPS (total)
- Low power operation with standby/power-down modes
- Industrial temperature range: -40°C to +85°C
- Available in small, low-profile packages suitable for dense designs
