description
The TLC1518 and TLC1514 are a family of high-performance, 10-bit, low power, 1.4 µs, CMOS SAR analog-to-digital converters ADC which operate from a single 5 V power supply. These devices have three digital inputs and a 3-state output [chip select CS, serial input-output clock SCLK, serial data input SDI, and serial data output SDO] that provide a direct 4-wire interface to the serial port of most popular host microprocessors SPI interface. When interfaced with a DSP, a frame sync FS signal is used to indicate the start of a serial data frame.
