Overview
The ADS1672IPAGRG4, produced by Texas Instruments, is a high-speed, high-precision analog-to-digital converter (ADC) that utilizes an advanced delta-sigma architecture. This ADC operates at speeds up to 625 kilosamples per second (kSPS) and is renowned for its outstanding AC performance and DC accuracy. It features a low-drift, chopper-stabilized modulator with out-of-range detection and a dual-path programmable digital filter, allowing users to select between low-latency and wide-bandwidth filter paths. The device is controlled through I/O pins without the need for register programming and includes a dedicated START pin for direct control of conversions. The ADS1672IPAGRG4 is suitable for a variety of applications requiring high precision and speed.
