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 DV

if it is not used (such

as in an SPI interface). When SDI is tied to DV , 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.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
