Texas Instruments' (TI) successive approximation (SAR) analog-to-digital converter (ADC) achieves four mega samples per second (MSPS) at any resolution. Designed from the company's Burr-Brown product line, the device is targeted at applications requiring high speed and low power, such as optical networking, portable medical systems, high-speed data acquisition, spectrum analyzers, imaging and telecommunications.
The ADS7881 offers designers a complete solution by integrating an internal reference and reference buffer. The device has a pseudo-differential, unipolar input range (0 to 2.5V) common to many high speed ADCs. It offers a 12-bit interface with an additional byte mode that provides easy interface with 8-bit processors. A nap mode reduces power dissipation to 10mW and a power down mode consumes 10uW.
The ADS7881 comes in a 48-lead TQFP package. $7.00 (1000).
