AD9633BCPZRL7-80

Analog To Digital Converters (ADC) Overview

The AD9633BCPZRL7-80 is a quad-channel, 12-bit analog-to-digital converter (ADC) from Analog Devices Inc., operating at a maximum sampling rate of 80 MSPS. It features a 650 MHz full-power analog bandwidth and a 2 V p-p differential input voltage range. The device utilizes a single 1.8 V supply for both analog and digital domains, consuming approximately 313 mW to 400 mW depending on the mode. Key performance metrics include a signal-to-noise ratio (SNR) of 71 dBFS and a spurious-free dynamic range (SFDR) of 91 dBc. It employs serial LVDS outputs with ANSI-644 compliance and includes an internal 1.0 V reference.

Analog To Digital Converters (ADC) Procurement Notes

Verify the RL7 suffix indicates reel packaging when sourcing. Confirm the -80 designation matches the required 80 MSPS sampling speed. Ensure compatibility with the 48-lead LFCSP package dimensions for PCB layout. Check RoHS compliance status for environmental regulations. Validate that the specific revision F datasheet applies to the manufactured lot.

Analog To Digital Converters (ADC) Selection Notes

Select this component when four independent 12-bit channels are required in a compact space. Consider the 80 MSPS limit if higher throughput is needed, opting for the -105 or -125 variants. Evaluate the 1.8 V supply requirement against system power rails. Assess the need for serial LVDS interfaces versus parallel alternatives. Verify thermal management capabilities for the LFCSP package under continuous operation.

Analog To Digital Converters (ADC) Part Context

The AD9633 belongs to a family of high-performance, low-power quad ADCs designed for cost-sensitive applications. It shares pin compatibility with the AD9253 14-bit quad ADC, facilitating design transitions. The device integrates essential functions like clock dividers and output drivers to minimize external component count. It represents a solution balancing dynamic performance with power efficiency in a small form factor.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9633BCPZ-80 is the non-reel equivalent part number. The AD9633BCPZ-105 and AD9633BCPZ-125 offer higher sampling rates but maintain pin compatibility. Cross-reference with the AD9253 for 14-bit resolution options in similar packages.
