description  
The TLC2551/2552/2555 are a family of high performance, 12-bit, low power, miniature 1.5 µs, 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 µs using 20 MHz SCLK.
