Overview
The LTC2320IUKG-12#PBF 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 offers a range of features that make it ideal for applications requiring simultaneous sampling of multiple channels.
Operating from a single 3.3 V or 5 V supply, the LTC2320-12 provides an 8 VP-P differential input range, ensuring a wide dynamic range with high common mode rejection. The ADC features a low noise design, achieving 77 dB signal-to-noise ratio (SNR) and –90 dB total harmonic distortion (THD) at an input frequency of 500 kHz.
