description  
The TLV2544Q, TLV2548Q, and TLV2548M are a family of high performance, 12-bit low power, 3.5 µs, 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.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of  
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.  
Copyright 2002, Texas Instruments Incorporated  
PRODUCTION DATA information is current as of publication date.  
Products conform to specifications per the terms of Texas Instruments  
standard warranty. Production processing does not necessarily include  
testing of all parameters.
