ADS7954SRGET TI ADC | 24-VQFN (4x4) | 4-Ch, 12-Bit, 1MSPS, SPI

Product Overview

The ADS7954SRGET is a 4-channel, 12-bit, successive-approximation register (SAR) analog-to-digital converter (ADC) from Texas Instruments. It features a maximum sampling rate of 1 MSPS and operates from a single 2.7V to 5.25V supply. The device includes an internal reference (2.5V) and a 4-channel multiplexer, making it ideal for multi-channel data acquisition systems. The SPI-compatible serial interface simplifies connection to microcontrollers and DSPs. Housed in a compact 24-VQFN (4x4 mm) package, it is suitable for space-constrained applications.
