description  
The TLC3574, TLC3578, TLC2574, and TLC2578 are a family of high-performance, low-power, CMOS  
analog-to-digital converters (ADC). TLC3574/78 is a 14-bit ADC; TLC2574/78 is a 12-bit ADC. All parts operate  
from single 5-V analog power supply and 3-V to 5-V digital supply. The serial interface consists of four digital  
input [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 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  
DD  
DD  
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.
