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 VCCand digitizes the input at a maximum 1.25 MSPS 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 uA 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.
