description
The TLV2544Q, TLV2548Q, and TLV2548M are a family of high performance, 12-bit low power, 3.5
s, CMOS
analog-to-digital converters (ADC) which operate from a single 3-V to 5.5-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.
