Overview
The ADS1000A0IDBVT is a 12-bit, low-power analog-to-digital converter (ADC) produced by Texas Instruments. It features a tiny SOT-23 package with 6 pins, making it ideal for applications where space and power consumption are critical. The device 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 includes a programmable gain amplifier (PGA) with gains of 1, 2, 4, or 8, and an I2C-compatible serial interface with two available addresses.
