Overview
The LTC1863IGN#PBF is a 12-bit, 8-channel analog-to-digital converter (ADC) produced by Analog Devices Inc. This component is part of the LTC1863/LTC1867 family, which are pin-compatible ADCs with serial I/O and an internal reference. The LTC1863 is designed for low-power and space-sensitive applications, drawing only 1.3mA from a single 5V supply at a sampling rate of 200ksps. It features automatic nap and sleep modes, making it suitable for power-sensitive applications.
