Overview
The LTC2313-12, produced by Analog Devices Inc., is a 12-bit, 2.5 million samples per second (Msps) serial sampling analog-to-digital converter (ADC). This device is designed to offer high performance and low power consumption, making it ideal for compact, high-speed systems. It operates from a single 3V or 5V supply and draws only 5mA of current, which decreases at lower sampling rates as the device automatically enters nap mode after conversions.
