AD9650BCPZ-65

Analog To Digital Converters (ADC) Overview

The AD9650BCPZ-65 is a dual, 16-bit analog-to-digital converter (ADC) operating at a maximum sampling rate of 65 MSPS. 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 performance metrics include an SNR of 83 dBFS at 9.7 MHz input and 82 dBFS at 30 MHz input. The component is housed in a 64-lead LFCSP package and is rated for the industrial temperature range of −40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix BCPZ indicates the 65 MSPS variant and LFCSP-64 packaging. Confirm RoHS compliance status through official Analog Devices documentation or authorized distributor declarations. Ensure the ordering code matches the required sample rate and package type for your design requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring 16-bit resolution at 65 MSPS with high dynamic range. Consider the pin compatibility with AD9268 and other dual families if migration across resolutions is needed. Evaluate power consumption requirements against the 397 mW typical DC input power at 65 MSPS. Ensure the system can support the 1.8 V supply rails and appropriate clocking infrastructure.

Analog To Digital Converters (ADC) Part Context

The AD9650 series includes variants with different maximum sampling rates: 25 MSPS, 65 MSPS, 80 MSPS, and 105 MSPS. All variants share the same 64-lead LFCSP package and core architecture. The BC prefix typically denotes the commercial/industrial temperature grade version. This specific part is optimized for mid-range bandwidth applications within the broader high-speed ADC portfolio.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include AD9650BCPZ-25, AD9650BCPZ-80, and AD9650BCPZ-105 for different speed grades. Other compatible devices in the family are AD9268, AD9269, AD9251, AD9231, and AD9204.
