† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under electrical characteristics and timing characteristics is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.DescriptionThe 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.
