Overview
The LTC2333ILX-16#PBF is a 16-bit, low-noise, 8-channel multiplexed successive approximation register (SAR) analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is part of the SoftSpan™ family, known for its flexibility and high performance in various high-voltage applications. The LTC2333-16 operates from a 5V low voltage supply and can be configured to accept a range of input signals, including ±10.24V, 0V to 10.24V, ±5.12V, or 0V to 5.12V on any channel. It features integrated picoamp-input analog buffers, a wide input common mode range, and high common-mode rejection ratio (CMRR), making it ideal for directly digitizing a variety of signals with minimal board space and power consumption.
