AS1521 Overview
The AS1520/AS1521 are low-power, 8/4-channel, 400/ 300ksps, 10-bit analog-to-digital (A/D) converters specifically designed to operate with single-supply devices. Superior AC characteristics, very low power consumption, and highly-reliable packaging make these ultrasmall devices perfect for battery-powered remote-sensor and data-acquisition devices. The successive-approximation register (SAR), highspeed sampling,...
