Overview
The LTC2344-16, specifically the LTC2344HUH-16 model, is a high-performance analog-to-digital converter (ADC) produced by Analog Devices Inc. This component is a 16-bit, low noise, 4-channel simultaneous sampling successive approximation register (SAR) ADC. It features differential inputs with a wide common mode range, making it versatile for various signal processing applications. The ADC operates from a 5V supply and can be configured to accept different input signal ranges on a conversion-by-conversion basis. Its high signal-to-noise ratio (SNR) and low integral nonlinearity (INL) make it an ideal choice for applications requiring wide dynamic range and high accuracy.
