AD9645BCPZRL7-80

Analog To Digital Converters (ADC) Overview

The AD9645BCPZRL7-80 is a dual-channel, 14-bit analog-to-digital converter (ADC) from Analog Devices Inc. It operates at a maximum sampling rate of 80 MSPS and features serial LVDS digital outputs. The device utilizes a single 1.8 V power supply for both the analog core and digital drivers. Key performance metrics include a signal-to-noise ratio (SNR) of 75.6 dBFS at a 9.7 MHz input frequency and a spurious-free dynamic range (SFDR) of 96 dBc under the same conditions. The component is housed in a 32-lead LFCSP package with a 5 mm × 5 mm footprint.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix RL7 against the manufacturer's current documentation to confirm reel packaging specifications. Ensure the selected variant matches the required automotive or industrial temperature rating, as standard and W-grade versions have different operating ranges. Cross-reference the part number with official distributors to confirm availability and compliance status.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a dual-channel, high-resolution ADC with low power consumption is required. The 80 MSPS speed grade is suitable for applications where lower bandwidth reduces system power. Consider the pin compatibility with the 12-bit AD9635 if future migration to lower resolution is anticipated. Verify that the serial LVDS interface aligns with the target receiver's clocking capabilities.

Analog To Digital Converters (ADC) Part Context

The AD9645 belongs to a family of high-speed, low-power analog-to-digital converters designed for space-constrained applications. It offers pin compatibility with the 12-bit AD9635, facilitating design flexibility across different resolution requirements. The device is optimized for communications and instrumentation markets requiring high dynamic performance.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9645BCPZ-80 is a direct functional equivalent within the same series. The AD9645BCPZ-125 offers identical functionality but supports a higher 125 MSPS sampling rate. Both alternatives share the same package and pinout.
