Overview
The ADS1000A0IDBVR is a 12-bit, single-channel analog-to-digital converter (ADC) produced by Texas Instruments. This device is integrated into a compact SOT-23-6 package, making it ideal for applications where space and power consumption are critical. The ADS1000 operates from a single power supply ranging from 2.7V to 5.5V and performs conversions at a rate of 128 samples per second (SPS). It features a programmable gain amplifier (PGA) with gains of 1, 2, 4, or 8, allowing for the measurement of smaller signals with high resolution. The device is designed for low power consumption, with an active current of only 90µA and automatic power-down after each conversion in single-conversion mode.
