概述

Description

The AD6643BCPZ-250 is Analog Devices’ high-speed ADC (digital converter) in the AD6643 family. The -250 speed grade indicates up to 250 MSPS sampling, with a broad input bandwidth and high dynamic range suitable for RF/digital-communications, radar, instrumentation, and software-defined radio applications. It typically offers flexible outputs (LVDS or parallel), integrated front-end and clocking options, and low jitter/low distortion performance for demanding digitization tasks. The BCPZ suffix denotes the specific package and temperature grade. For exact resolution, input bandwidth, power, interface options, and pinout, consult the latest data sheet and application notes.

Features

Here are the typical features of AD6643BCPZ-250 (high-speed 14-bit ADC family). For exact specs, consult the latest datasheet.
- 14-bit resolution
- Up to 250 MSPS sampling rate
- Differential LVDS data outputs (multi–bit parallel output)
- On-chip track-and-hold
- Internal/external reference support
- Wide input range suitable for differential 2 Vpp-like full-scale
- Single-supply operation with low power and power-down mode
- Industrial temperature range (-40°C to +85°C)
- BCPZ package (compact high-speed packaging)
Note: exact I/O, reference, pinout, and power requirements can vary by revision; verify against the specific datasheet for -250 variant.

Package

Lead Frame Chip Scale Package (LFCSP), RoHS-compliant (BCPZ suffix).

Pinout

- Pin count: 48 pins (48‑lead LFCSP, package code BC PZ).
- Function: AD6643BCPZ-250 is a 14‑bit, 250 MSPS high‑speed analog‑to‑digital converter (single channel) with differential analog input, high‑speed parallel CMOS digital outputs, clock input, reference and power/ground/control pins for interfacing to digital systems.

Manufacturer

- Scientific/industrial instrumentation requiring wideband, high-speed ADC digitization

Equivalent

AD6643BCPZ-250 is Analog Devices’ AD6643 (14‑bit, 250 MSPS ADC). There are no guaranteed pin‑for‑pin direct equivalents. Comparable substitute ADCs (similar resolution/sample rate, but not drop‑in) include Analog Devices AD9467 (16‑bit, 250 MSPS), TI ADS5474 (14‑bit, higher‑rate series) and other 14‑bit/250 MSPS parts from ADI, TI or Maxim. For a true replacement or board-level cross‑reference, consult Analog Devices or your distributor.
