Description
The AD6643BCPZ-250 is Analog Devices’ high-speed ADC (part of the AD6643 family). It provides fast analogue-to-digital conversion suitable for RF, communications, instrumentation, and test equipment. It typically runs up to 250 MSPS with multi-bit resolution around 12–14 bits and LVDS-compatible outputs. The -BCPZ-250 suffix denotes the packaging (BCPZ) and a speed grade of 250 MSPS; it is offered in a RoHS-compliant plastic package. Features often include reference options (external or internal), wide input bandwidth, and single-ended or differential input depending on model. It requires an external clock and appropriate power rails; data is captured on a clock and presented on the LVDS digital outputs. For exact resolution, input range, power, timing, and packaging details, consult the AD6643 datasheet and Analog Devices’ product page.
Features
AD6643BCPZ-250 is a high-speed, 12-bit ADC. Key features (variant-specific datasheet should be checked for exact numbers):
- 12-bit resolution
- Up to about 65 MSPS sampling rate
- On-chip track-and-hold
- Internal 2.5 V reference (external reference option available)
- Analog input range: 0 to Vref (unipolar) with input buffer
- Flexible data interface (supports standard high-speed outputs; check variant for LVDS/CMOS options)
- Low power consumption with power-down modes
- Temperature range suitable for industrial use (-40°C to +85°C; confirm per part)
- Pb-free, RoHS-compliant BCPZ package
Note: For exact performance (SNR, SFDR, full-scale range, exact interface, and supply voltage/pinout), consult the AD6643BCPZ-250 datasheet.
