Overview
The LTC2225IUH#PBF is a 12-bit, 10Msps (Mega Samples Per Second) low-power analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is designed to digitize high-frequency, wide dynamic range signals, making it ideal for demanding applications in imaging and communications. It operates on a single 3V supply and features a separate output supply to drive logic levels from 0.5V to 3.6V. The ADC is packaged in a 32-pin QFN (5mm x 5mm x 0.75mm with EP) package, enhancing its suitability for space-constrained designs.
