Overview
The LTC2314-14, produced by Analog Devices Inc., is a 14-bit, 4.5Msps (Mega Samples Per Second) serial sampling Analog-to-Digital Converter (ADC). This device is designed for high-speed, low-power applications and features an integrated bandgap and reference buffer, providing a high-performance solution with a low drift of 20ppm/°C. The ADC operates from a wide analog supply range of 2.7V to 5.25V and draws only 6.2mA of current. It achieves outstanding AC performance with 77dB SINAD and –85dB THD while sampling a 500kHz input frequency, making it ideal for compact, high-speed systems.
