TLC3574IPW

Product Summary

The TLC3574IDW is a high-performance, low-power, CMOS analog-to-digital converter (ADC). TLC3574/78 is a 14-bit ADC; the TLC3574IDWis 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.
