DESCRIPTION  
The TLV2548 is a high performance, 12-bit low-power, 3.86-μs, CMOS analog-to-digital converter (ADC) which  
operates from a single 3.0-V to 5.5-V power supply. This device has 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 TI DSP, a frame sync (FS) signal is used to indicate the start of a serial data frame.  
In addition to a high-speed A/D converter and versatile control capability, this device has an on-chip analog  
multiplexer that can select any analog inputs or one of three internal self-test voltages. The sample-and-hold  
function is automatically started after the fourth SCLK edge (normal sampling) or can be controlled by a special  
pin, CSTART, to extend the sampling period (extended sampling). The normal sampling period can also be  
programmed as short (12 SCLKs) or as long (24 SCLKs) to accommodate faster SCLK operation popular among  
high-performance signal processors. The TLV2548 is designed to operate with very low power consumption. The  
power-saving feature is further enhanced with software/hardware/autopower-down modes and programmable  
conversion speeds. The conversion clock (OSC) and reference are built-in. The converter can use the external  
SCLK as the source of the conversion clock to achieve higher (up to 2.8 μs when a 20-MHz SCLK is used)  
conversion speed. Two different internal reference voltages are available. An optional external reference can also  
be used to achieve maximum flexibility.  
The TLV2548 is characterized for operation from –55°C to 125°C.
