TLC2551

The TLC2551/2552/2555 are a family of high performance, 12-bit, low power, miniature 1.5 ms, CMOS analog-to-digital converters (ADC). The TLC255x family uses a 5 V supply. Devices are available with single, dual, or single pseudo-differential inputs. The TLC2551 has a 3-state output chip select (CS ), serial output clock (SCLK), and serial data output (SDO) that provides a direct 3-wire interface to the serial port of most popular host microprocessors (SPI interface). When interfaced with a DSP, a frame sync signal (FS) is used to indicate the start of a serial data frame. The TLV2552/55 have a shared CS /FS terminal.

TLC2551/2/5 are designed to operate with very low power consumption. The power saving feature is further enhanced with an autopower-down mode. This product family features a high-speed serial link to modern host processors with SCLK up to 20 MHz. TLC255x family uses the SCLK as the conversion clock, thus providing synchronous operation allowing a minimum conversion time of 1.5 ms using 20 MHz SCLK.
