Overview
The LTC2313-14, produced by Analog Devices Inc., is a 14-bit, 2.5Msps serial sampling Analog-to-Digital Converter (ADC). This device is designed for high-speed, low-power applications and features an integrated low drift reference and reference buffer. It operates from a single 3V or 5V supply, drawing only 5mA, and achieves outstanding AC performance with 77dB SINAD and –85dB THD. The LTC2313-14 is ideal for compact, high-speed systems due to its high sample rate-to-power ratio and automatic nap mode at lower sampling rates.
