Overview
The ADS7052IRUGR, produced by Texas Instruments, is a 14-bit, 1-MSPS (mega-samples per second) successive-approximation register (SAR) type analog-to-digital converter (ADC). This device is part of a family of high-speed, low-power, single-channel ADCs that offer multiple resolutions, throughputs, and analog input variants. The ADS7052IRUGR is notable for its small package size, low power consumption, and excellent performance characteristics, making it suitable for a wide range of applications, including those in space-constrained and battery-powered systems.
