Overview
The LTC1867L, produced by Analog Devices Inc., is a micropower, 3V, 16-bit, 8-channel analog-to-digital converter (ADC) with a sampling rate of 175ksps. This device is part of the LTC1863L/LTC1867L family, which are pin-compatible and offer high precision and low power consumption. The ADC features a configurable 8-channel analog input multiplexer that can be set up for single-ended or differential inputs and unipolar or bipolar conversions. It operates from a single 2.7V supply, drawing only 750µA, making it suitable for power-sensitive applications. The device is housed in a compact 16-pin narrow SSOP package, ideal for space-sensitive and low-power applications.
