General Description

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).
