Overview
The LTC2392-16 is a high-performance, low noise, 16-bit successive approximation register (SAR) analog-to-digital converter (ADC) produced by Analog Devices Inc. This ADC operates from a single 5V supply and supports a large ±4.096V fully differential input range, making it ideal for applications requiring maximum dynamic range. It achieves high accuracy with ±2LSB INL max and no missing codes at 16 bits, along with a signal-to-noise ratio (SNR) of 94dB (typical). The device includes a precision internal reference with a guaranteed 0.5% initial accuracy and a ±20ppm/°C temperature coefficient. Its fast 500ksps throughput and low power consumption of 110mW at 500ksps, along with nap and sleep power-down modes, make it suitable for a wide variety of high-speed applications.
