Overview
Description
The LTC2217IUP is a 16-bit, 105Msps low-power ADC from Analog Devices, designed for high-performance applications. It features excellent SNR (79.3dB) and SFDR (100dB) at 70MHz input, making it ideal for communications, medical imaging, and instrumentation.
Key highlights:
- Low power: Consumes 1.1W at 105Msps.
- Flexible input: Supports 1VP-P to 2VP-P full-scale range.
- LVDS outputs: Reduces noise and simplifies PCB routing.
- Integrated digital functions: Includes offset correction and data formatting.
Packaged in a 64-pin QFN (7mm × 7mm), it suits space-constrained designs. The LTC2217IUP balances speed, resolution, and power efficiency, making it a strong choice for demanding signal-processing tasks.
