AD9650BCPZ-80

Analog To Digital Converters (ADC) Overview

The AD9650BCPZ-80 is a dual-channel, 16-bit analog-to-digital converter (ADC) operating at an 80 MSPS sampling rate. It features a multistage differential pipelined architecture with integrated output error correction logic and shared voltage reference. The device supports IF sampling frequencies up to 300 MHz with a 2.7 V p-p analog input range. It operates from a single 1.8 V analog supply and a separate 1.8 V digital output driver supply, supporting both CMOS and LVDS outputs. Key specifications include an SNR of 82 dBFS at 30 MHz input, SFDR of 92 dBc, and power consumption of 537 mW per channel at maximum data rate.

Analog To Digital Converters (ADC) Feature Summary

• Flexible power-down options for significant power savings
• SPI-compatible serial interface for setup and control

Analog To Digital Converters (ADC) Applications

• Industrial instrumentation
• X-Ray, MRI, and ultrasound equipment
• High speed pulse acquisition
• Direct conversion receivers
• General-purpose software radios

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix BCPZ indicates the LFCSP-64 package and industrial temperature range (-40°C to +85°C). Confirm that the -80 designation corresponds to the 80 MSPS conversion rate variant within the AD9650 family. Ensure compatibility with 1.8 V supply requirements for both AVDD and DRVDD pins during procurement planning.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a dual-channel, 16-bit resolution ADC is required for signals up to 300 MHz. The 80 MSPS rate suits applications needing higher bandwidth than the 25 or 65 MSPS variants but lower than the 105 MSPS version. Consider the pin compatibility with AD9268 and other dual families if migration across resolutions is planned. Evaluate thermal dissipation needs given the 537 mW per channel power consumption at full speed.

Analog To Digital Converters (ADC) Part Context

The AD9650BCPZ-80 belongs to the AD9650 series of high-speed, low-power dual ADCs. It shares architectural similarities with the AD9268, AD9269, AD9251, AD9231, and AD9204 families, allowing for pin-compatible upgrades. This specific model provides an 80 MSPS sampling rate option, bridging the gap between the 65 MSPS and 105 MSPS variants in the product line.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible replacements include AD9650BCPZ-25, AD9650BCPZ-65, and AD9650BCPZ-105 for different sampling rates. Other compatible parts in the family are AD9268, AD9269, AD9251, AD9231, and AD9204.
