Overview
The LTC2313ITS8-14, 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, making it ideal for compact and power-efficient systems. The LTC2313ITS8-14 achieves outstanding AC performance with 77dB SINAD and –85dB THD at a 2.5Msps sampling rate, and it supports a high-speed SPI-compatible serial interface that is compatible with 1.8V, 2.5V, 3V, and 5V logic levels.
