Overview
The LTC2320CUKG-12#TRPBF is a high-performance, octal 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is designed for high-speed data acquisition and features simultaneous sampling of eight channels, making it ideal for applications requiring precise and fast data conversion.
Operating from a single 3.3 V or 5 V supply, the LTC2320CUKG-12#TRPBF offers a wide dynamic range with high common mode rejection, thanks to its 8 VP-P differential input range. The device includes an onboard low drift internal reference and supports CMOS or LVDS SPI-compatible serial interfaces.
