概述
Description
The AD6645ASVZ-80 is Analog Devices’ high-speed, 14‑bit ADC. It samples up to 80 MSPS and is intended for RF front ends, communications receivers, and high‑end instrumentation.
Key points:
- Resolution and speed: 14 bits, up to 80 MSPS.
- Interfaces: differential analog input with LVDS (digital) outputs; internal sample-and-hold.
- Package/grade: ASVZ denotes the package variant and RoHS/compliant version; “-80” denotes the 80 MSPS speed grade.
- Power and clock: requires a suitable analog/digital supply and an external clock; typically used with a reference for accuracy.
Typical uses include digital down‑conversion in receivers, test instrumentation, and data acquisition systems needing high dynamic range at moderate sample rates.
For exact specs, pinout, timing, reference requirements, and evaluation boards, consult the AD6645 datasheet and Analog Devices’ resources. If you’d like, I can pull out the key electrical specs from the datasheet.
