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). 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. CS can be tied to ground if only one converter is used. FS must be tied to DVDD if it is not used (such
as in an SPI interface). When SDI is tied to DVDD, the device is set in hardware default mode after power-on,
and no software configuration is required. In the simplest case, only three wires (SDO, SCLK, and CS or FS)
are needed to interface with the host.
