Overview
The LTC2344-16, produced by Analog Devices Inc., is a 16-bit, low noise, 4-channel simultaneous sampling successive approximation register (SAR) analog-to-digital converter (ADC). This device is designed to operate from a 5V supply and features differential, wide common mode range inputs. The LTC2344-16 is part of the SoftSpan™ ADC family, allowing each channel to be independently configured on a conversion-by-conversion basis to accept various input signal ranges such as ±4.096V, 0V to 4.096V, ±2.048V, or 0V to 2.048V. This flexibility, combined with its high performance characteristics, makes it an ideal choice for applications requiring wide dynamic range and precise signal digitization.
