Overview
The LTC2320IUKG-16 is a high-performance, low noise, and high-speed octal 16-bit successive approximation register (SAR) analog-to-digital converter (ADC) produced by Analog Devices Inc. This component is designed to operate from a single 3.3V or 5V supply and features differential inputs with a wide input common mode range, making it ideal for applications requiring a wide dynamic range and high common mode rejection.
The LTC2320IUKG-16 is characterized by its fast 1.5Msps per channel throughput with no latency, an onboard low drift temperature-compensated reference, and a high-speed SPI-compatible serial interface that supports both CMOS and LVDS logic.
