Analog to Digital Converters

TLC2578IPW Description

The TLC2578IPW from Texas Instruments is a high-performance 12-bit SAR (Successive Approximation Register) ADC designed for precision analog-to-digital conversion in demanding applications. Housed in a 24-pin TSSOP package, this IC integrates a single ADC with SPI-compatible data interface, offering a sampling rate of 200k samples per second (SPS). It operates with a 5V analog supply and a flexible 2.7V to 5.5V digital supply, making it suitable for mixed-voltage systems. The device supports 4 or 8 multiplexed inputs with a 1:1 sample-and-hold (S/H) to ADC ratio, ensuring accurate signal acquisition. Its external reference capability allows customization for varying precision requirements.
