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 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.
