The LTC1863LIGN#PBF is a 8-channel micropower 12-bit Analog-to-digital Converter (ADC) with serial I/O and an internal reference. The input multiplexer can be configured for either single-ended or differential inputs or unipolar or bipolar conversions. The ADC converts 0 to 2.5V unipolar inputs or ±1.25V bipolar inputs. The ADC typically draws only 750μA from a single 2.7V supply. The automatic nap and sleep modes benefit power sensitive applications. It can be used in space-sensitive as well as low power applications.
