Overview
The ADS7057IRUGR, produced by Texas Instruments, is a 14-bit, 2.5-MSPS successive-approximation register (SAR) type analog-to-digital converter (ADC). This device is part of a family of pin-to-pin compatible, high-speed, low-power ADCs that offer various resolutions, throughputs, and analog input variants. The ADS7057 supports fully-differential inputs in the range of ±AVDD, with AVDD ranging from 2.35 V to 3.6 V. It features an internal offset calibration mechanism that ensures excellent offset specifications across the entire operating range of AVDD and temperature. The device is packaged in a small 8-pin X2QFN package and operates over an extended industrial temperature range of –40°C to +125°C, making it suitable for space-constrained and battery-powered applications requiring high-speed, high-resolution data acquisition.
