Overview
The LTC2295, produced by Analog Devices Inc., is a 14-bit, 10Msps (Mega Samples Per Second) dual analog-to-digital converter (ADC) designed for digitizing high-frequency, wide dynamic range signals. This low-power ADC operates on a single 3V supply (ranging from 2.7V to 3.4V) and is ideal for demanding applications in imaging and communications. It features integrated dual 14-bit ADCs, a high signal-to-noise ratio (SNR) of 74.4dB, and a spurious free dynamic range (SFDR) of 90dB, making it suitable for signals well beyond the Nyquist frequency.
