description  
The TLV1572 is a high-speed 10-bit successive-approximation analog-to-digital converter (ADC) that operates  
from a single 2.7-V to 5.5-V power supply and is housed in a small 8-pin SOIC package.  
The TLV1572 accepts an analog input range from 0 to V  
and digitizes the input at a maximum 1.25 MSPS  
CC  
throughput rate. The power dissipation is only 8 mW with a 3-V supply or 25 mW with a 5-V supply. The device  
features an auto-powerdown mode that automatically powers down to 10 µA whenever a conversion is not  
performed.  
The TLV1572 communicates with digital microprocessors via a simple 3- or 4-wire serial port that interfaces  
directly to the Texas Instruments TMS320 DSPs and (Q)SPI compatible microcontrollers without using  
additional glue logic.  
Very high throughput rate, simple serial interface, SO-8 package, 3-V operation, and low power consumption  
make the TLV1572 an ideal choice for compact or remote high-speed systems.
