Overview
The ADS7816UCG4 is a high-performance, 12-bit analog-to-digital converter (ADC) from Texas Instruments, originally developed by Burr-Brown. This Successive Approximation Register (SAR)-based ADC is designed for various applications requiring high precision and speed. It features a single input channel with differential configuration and supports sampling rates up to 200k samples per second. The device operates on an external reference supply and has a voltage range of 5V for both analog and digital signals. It is packaged in an 8-SOIC case, making it suitable for surface-mount applications. The ADS7816UCG4 is designed for use in industrial and commercial environments with operating temperatures ranging from -40°C to 85°C.
