Overview
The LTC2312ITS8-12#TRMPBF is a 12-bit, 500ksps serial sampling analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is designed for high-performance, low-power applications and features an integrated low drift reference and reference buffer. It operates from a single 3V or 5V supply, drawing only 3mA of current, making it ideal for compact, high-speed systems. The ADC achieves outstanding AC performance with a signal-to-noise and distortion ratio (SINAD) of 72.7dB and a total harmonic distortion (THD) of –84dB while sampling at 500ksps.
