Overview
The LTC2357CLX-16#PBF is a high-performance, 16-bit, low-noise, 4-channel simultaneous sampling successive approximation register (SAR) analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is designed to operate with a wide input common mode range and features integrated picoamp-input analog buffers, making it ideal for various high-voltage applications requiring a wide dynamic range. The ADC supports flexible high-voltage supplies and can be configured on a conversion-by-conversion basis to accept different signal ranges, including ±10.24V, 0V to 10.24V, ±5.12V, or 0V to 5.12V. It operates from a 5V low-voltage supply and offers pin-selectable SPI CMOS (1.8V to 5V) and LVDS serial interfaces.
