Product Summary

The TLC3548IDW is a 14-bit resolution high-performance, low-power, CMOS analog-to-digital converter (ADC). It operates from a single 5-V analog power supply and 3-V to 5-V digital supply. The TLC3548IDW consists of four digital inputs [chip select (CS), frame sync (FS), serial input-output clock (SCLK), serial data input (SDI)], and a 3-state serial data output (SDO). CS (works as SS, slave select), SDI, SDO, and SCLK form an SPI interface. FS, SDI, SDO, and SCLK form a DSP interface. The frame sync signal (FS) indicates the start of a serial data frame being transferred.
