AD9649BCPZRL7-65

Analog To Digital Converters (ADC) Overview

The AD9649BCPZRL7-65 is a monolithic, single-channel 14-bit analog-to-digital converter (ADC) from Analog Devices. It operates at a maximum sampling rate of 65 MSPS and utilizes a multistage differential pipeline architecture with output error correction logic to ensure no missing codes across the full operating temperature range. The device features an on-chip voltage reference and sample-and-hold circuit, supporting a 2 V p-p differential analog input. It requires a single 1.8 V analog supply and accommodates digital output driver supplies ranging from 1.8 V to 3.3 V. The component is housed in a 32-lead RoHS-compliant LFCSP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix RL7 against official documentation to confirm reel packaging specifications. Ensure compatibility with the required 65 MSPS performance tier within the AD9649 family. Cross-reference pinout details with the 32-lead LFCSP outline dimensions provided in the datasheet to validate PCB footprint requirements before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a 65 MSPS conversion rate is sufficient for the application bandwidth. The device supports offset binary, gray code, or twos complement data formats. Consider the separate DRVDD supply for interfacing with 1.8 V or 3.3 V logic families. Verify that the 700 MHz analog input bandwidth meets the signal frequency requirements.

Analog To Digital Converters (ADC) Part Context

The AD9649 belongs to a family of 14-bit ADCs available in 20, 40, 65, and 80 MSPS variants. It shares pin compatibility with the AD9629 (12-bit) and AD9609 (10-bit) converters, facilitating migration paths between different resolution tiers while maintaining similar form factors and design guidelines.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9649BCPZ-65 is a direct equivalent part number without the reel suffix. Other speed grades such as AD9649BCPZ-20, AD9649BCPZ-40, and AD9649BCPZ-80 are pin-compatible but offer different maximum sampling rates.
