DESCRIPTION
The LTC®1863L/LTC1867L are pin compatible, 8-channel 12-/16-bit A/D converters with serial I/O and an internal reference.
The 8-channel input multiplexer can be configured for either single-ended or differential inputs and unipolar or bipolar conversions (or combinations thereof). The ADCs convert 0V to 2.5V unipolar inputs or ±1.25V bipolar inputs. The ADCs typically draw only 750µA from a single 2.7V supply. The automatic nap and sleep modes benefit power sensitive applications.
