The TLC3544 and TLC3548 are a family of 14-bit resoluTIon high-performance, low-power, CMOS analog-to-digital converters (ADC). All devices operate from a single 5-V analog power supply and 3-V to 5-V digital supply. The serial interface 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. When mulTIple converters connect to one serial port of a DSP, CS works as the chip select to allow the host DSP to access the individual converter.
