Analog to Digital Converters

TLC2578IDW Description

The TLC2578IDW from Texas Instruments is a high-performance 12-bit SAR (Successive Approximation Register) analog-to-digital converter (ADC) designed for precision measurement applications. Housed in a 24-pin SOIC package, this ADC integrates a single-channel converter with SPI-compatible serial interface, enabling seamless communication with microcontrollers and digital systems. It operates with a dual supply range (analog: 5V, digital: 2.7V to 5.5V), making it versatile for mixed-voltage environments. With a sampling rate of 200k samples per second (ksps) and 4 or 8 configurable inputs, it delivers high-speed, accurate data acquisition. The device supports external voltage reference, enhancing flexibility in calibration and accuracy tuning.
