AD9644CCPZ-80

Analog To Digital Converters (ADC) Overview

The AD9644CCPZ-80 is a dual-channel, 14-bit analog-to-digital converter (ADC) operating at an 80 MSPS sampling rate. It features JESD204A coded serial digital outputs and operates from a single 1.8 V supply. The device utilizes a multistage differential pipelined architecture with integrated output error correction logic. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 70.0 dBFS at 70 MHz input frequency and a Spurious-Free Dynamic Range (SFDR) of 73 dBc under the same conditions. The part is housed in a 48-lead LFCSP package and supports industrial temperature ranges.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix to ensure the component matches the required speed grade and temperature range. Confirm that the package type corresponds to the design footprint. Check for RoHS compliance status if environmental regulations apply to the manufacturing process. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a dual-channel solution with JESD204A output is required for space-constrained designs. Consider the SNR and SFDR specifications relative to the input signal frequency and amplitude. Evaluate the power consumption against system thermal constraints. Verify compatibility with the host processor's SPI interface for configuration control.

Analog To Digital Converters (ADC) Part Context

This component belongs to the AD9644 family of high-speed analog-to-digital converters. The family includes variants with different sampling rates, such as the 155 MSPS version. The CCPZ suffix indicates a specific commercial or industrial grade variant within the broader product line, distinguished by its packaging and operational characteristics compared to other suffixes like BCPZ.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements include the AD9644BCPZ-80, which shares the same functional specifications but may differ in performance grades or testing criteria. Other family members like the AD9644-155 offer higher sampling rates but require verification of pinout and electrical compatibility.
