Analog to Digital Converters

TLC3574IPW Description

The TLC3574IPW from Texas Instruments is a high-performance 14-bit SAR (Successive Approximation Register) analog-to-digital converter (ADC) designed for precision measurement applications. Housed in a compact 20-TSSOP package, this ADC integrates a single converter with SPI-compatible data interface, enabling seamless communication with microcontrollers or DSPs. It operates with a dual-supply configuration—5V analog supply and 2.7V to 5.5V digital supply—making it versatile for mixed-voltage systems. With a sampling rate of 200kSPS and 1:1 sample-and-hold (S/H) to ADC ratio, it delivers high-speed, low-latency conversions. The device supports 2 or 4 differential inputs, offering flexibility for multi-channel systems.
