Overview
The LTC2393-16, produced by Analog Devices Inc., is a high-performance, low noise, 16-bit successive approximation register (SAR) analog-to-digital converter (ADC). This ADC operates from a single 5V supply and is designed to support a large ±4.096V fully differential input range, making it ideal for applications requiring maximum dynamic range. The device achieves high accuracy with ±2LSB INL max and no missing codes at 16 bits, along with a signal-to-noise ratio (SNR) of 94.2dB (typical). It includes a precision internal reference and supports fast 1Msps throughput with no cycle latency in both parallel and serial interface modes.
