AD9650BCPZRL7-65

Analog To Digital Converters (ADC) Overview

The AD9650BCPZRL7-65 is a dual-channel, 16-bit analog-to-digital converter (ADC) from Analog Devices Inc., operating at a sampling rate of 65 MSPS. It features a multistage differential pipelined architecture with integrated output error correction logic and a shared internal voltage reference. The device supports input frequencies up to 300 MHz with a differential analog input range of 2.7 V p-p. It operates on a single 1.8 V analog supply and a separate 1.8 V digital output driver supply, supporting both CMOS and LVDS output formats. Key performance metrics include an SNR of 82 dBFS at 30 MHz input and 65 MSPS data rate, and an SFDR of 90 dBc under the same conditions. Power consumption is 408 mW for DC input and 533 mW for sine wave input in CMOS mode. The component is housed in a 64-lead LFCSP package and is rated for operation between -40°C and +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix RL7 indicates tape and reel packaging when sourcing this component. Confirm that the 65 MSPS variant matches the required system timing constraints. Ensure compatibility with the 64-lead LFCSP footprint during PCB layout. Check for moisture sensitivity level requirements prior to soldering. Validate that the 1.8 V supply rails meet the absolute maximum ratings defined in the datasheet.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a dual-channel 16-bit ADC with 65 MSPS throughput is required. Consider the AD9650BCPZ-25 or AD9650BCPZ-105 if different sampling rates are needed. Evaluate the LVDS output option if long-distance signal integrity is critical. Compare power dissipation against thermal management capabilities in the target enclosure. Verify pin compatibility with existing designs using AD9268 or AD9269 families.

Analog To Digital Converters (ADC) Part Context

The AD9650 series includes variants with sampling rates of 25, 65, 80, and 105 MSPS. The BCPZ designation refers to the lead-free LFCSP package. The RL7 suffix typically denotes tape and reel packaging for automated assembly. This component belongs to Analog Devices' high-speed ADC portfolio designed for wide dynamic range applications.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include the AD9268, AD9269, AD9251, AD9231, and AD9204. These parts allow migration across resolutions and bandwidths within the dual-channel family. Verify electrical specifications such as SNR and power consumption when substituting.
