Overview
The LTC2335CLX-16, produced by Analog Devices Inc., is a 16-bit, low noise, 8-channel multiplexed successive approximation register (SAR) analog-to-digital converter (ADC). This device features differential, wide common mode range inputs and operates from a 5V low voltage supply. The LTC2335CLX-16 is part of the LTC2335-16 series, known for its SoftSpan architecture, which allows flexible input ranges on a conversion-by-conversion basis, including ±10.24V, 0V to 10.24V, ±5.12V, or 0V to 5.12V. This flexibility, combined with its high accuracy and low noise characteristics, makes it an ideal choice for various high voltage applications requiring wide dynamic range.
