Texas Instruments TLV2542CDGK

Description
The TLV2541, TLV2542, and TLV2545 are a family of high-performance, 12-bit, low-power, miniature, CMOS analog-to-digital converters (ADCs). They operate from a single 2.7-V to 5.5-V supply and are available with single, dual, or single pseudo-differential inputs. Each device has a chip select (CS), serial 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 TMS320 DSP, a frame sync signal (FS) can be used to indicate the start of a serial data frame on CS for all devices or FS for the TLV2541.
