AD9609BCPZ-65

Analog To Digital Converters (ADC) Overview

The AD9609BCPZ-65 is a monolithic, single-channel 10-bit analog-to-digital converter (ADC) from Analog Devices Inc. It operates at a maximum sampling rate of 65 MSPS with a 1.8 V analog supply and supports 1.8 V to 3.3 V digital output supplies. The device features a differential input bandwidth of 700 MHz and a 2 V p-p differential analog input span. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 61.5 dBFS at a 9.7 MHz input frequency and 61.0 dBFS at 200 MHz. Spurious-Free Dynamic Range (SFDR) reaches 75 dBc at 9.7 MHz and 73 dBc at 200 MHz. Power consumption is 45 mW at 20 MSPS and 76 mW at 80 MSPS. It utilizes a multistage differential pipeline architecture with on-chip voltage reference and sample-and-hold circuitry.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific speed grade suffix (-65) against the required sampling rate during procurement. Confirm that the LFCSP-32 package dimensions and exposed paddle soldering requirements align with the PCB layout guidelines. Ensure the ordering documentation matches the exact Analog Devices part number to avoid confusion with other speed grades in the AD9609 family.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 10-bit resolution and 65 MSPS sampling rate are required within a compact form factor. Consider the AD9609BCPZ-65 for designs needing pin compatibility with the 12-bit AD9629 and 14-bit AD9649 converters. Evaluate the 700 MHz input bandwidth and low power consumption characteristics against system signal integrity and thermal constraints.

Analog To Digital Converters (ADC) Part Context

The AD9609BCPZ-65 belongs to the AD9609 family of 10-bit, 1.8 V ADCs available in multiple speed grades (20, 40, 65, and 80 MSPS). It shares the same 32-lead LFCSP package and functional block diagram as other variants in the series. This family is designed for easy migration between different resolution and speed requirements while maintaining a consistent interface and footprint.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9609BCPZ-20, AD9609BCPZ-40, and AD9609BCPZ-80 are pin-compatible alternatives within the same family. For higher resolution needs, the AD9629 (12-bit) and AD9649 (14-bit) offer pin-compatible upgrades. Verify that the replacement part's sampling rate and power specifications meet the original design requirements.
