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, high-bandwidth track/hold circuitry, and multi-mode operation combine to make these devices highly-flexible and configurable. Both devices require low supply current (2.8mA @ 400ksps, AS1520; 2.
