Overview
The LTC2344IUH-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 features differential inputs with a wide common mode range, making it suitable for a variety of applications requiring high accuracy and wide dynamic range. Operating from a 5V supply, the LTC2344IUH-16 uses an internal reference and buffer, allowing each channel to be independently configured to accept different signal ranges such as ±4.096V, 0V to 4.096V, ±2.048V, or 0V to 2.048V on a conversion-by-conversion basis. The ADC supports pin-selectable SPI CMOS (1.8V to 5V) and LVDS serial interfaces, enhancing its versatility in different system designs.
