Overview
The LTC2348CLX-16 is a high-performance, 16-bit, low noise, 8-channel simultaneous sampling successive approximation register (SAR) analog-to-digital converter (ADC) produced by Analog Devices Inc. This device operates from a 5V low voltage supply and features flexible high voltage supplies, along with an internal reference and buffer. Each channel can be independently configured on a conversion-by-conversion basis to accept various input voltage ranges, including ±10.24V, 0V to 10.24V, ±5.12V, or 0V to 5.12V. The ADC is designed for high voltage applications requiring wide dynamic range, with key benefits including low noise, high precision, and the ability to disable individual channels to increase throughput on the remaining channels.
