Overview
The Texas Instruments ADS7828E/2K5G4 is a 12-bit analog-to-digital converter (ADC) designed for data acquisition applications. This device features an eight-input single-shot successive approximation register (SAR) architecture, allowing it to sample up to 50,000 times per second. It supports both external and internal reference types and operates within a single-supply voltage range of 2.7V to 5V. The ADS7828E/2K5G4 is housed in a compact 16-pin TSSOP package and is suitable for use in a wide range of temperatures from -40°C to 85°C.
