Overview
The LTC2341HUH-16 is a 16-bit, low noise, 2-channel simultaneous sampling successive approximation register (SAR) analog-to-digital converter (ADC) produced by Analog Devices Inc. This device features differential, wide common mode range inputs and operates from a 5V supply. The LTC2341-16 is part of the SoftSpan™ ADC family, allowing each channel to be independently configured on a conversion-by-conversion basis to accept various signal ranges such as ±4.096V, 0V to 4.096V, ±2.048V, or 0V to 2.048V. This flexibility, combined with its high signal-to-noise ratio (SNR) and low integral nonlinearity (INL), makes it an ideal choice for applications requiring wide dynamic range.
