The LTC1863CGN#PBF is a 12-bit Analog-to-digital Converter (ADC) with serial I/O and an internal reference. The ADC typically draws only 1.3mA from a single 5V supply. The 8-channel input multiplexer can be configured for either single-ended or differential inputs or unipolar or bipolar conversions. The automatic nap and sleep modes benefit power sensitive applications. It can be used in space-sensitive as well as low-power applications.
