AD9644BCPZ-80

Analog To Digital Converters (ADC) Overview

The AD9644BCPZ-80 is a dual-channel, 14-bit analog-to-digital converter (ADC) operating at a maximum sampling rate of 80 MSPS. 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 specifications include a signal-to-noise ratio (SNR) of 73.7 dBFS at 70 MHz input frequency and a spurious-free dynamic range (SFDR) of 92 dBc under the same conditions. Power consumption is rated at 423 mW at 80 MSPS. The component is housed in a 48-lead LFCSP package and supports an industrial temperature range of −40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix BCPZ against the manufacturer's ordering guide to confirm the exact speed grade and package variant. Ensure that the procurement documentation matches the required JESD204A interface configuration and voltage levels. Cross-reference the part number with the latest datasheet revision to validate all electrical parameters before finalizing orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high-performance dual-channel digitization within a compact form factor. The internal PLL allows users to provide a single ADC sampling clock while generating the corresponding JESD204A data rate clock. Consider the integer 1-to-8 input clock divider when designing the clock distribution network to optimize jitter performance and system synchronization.

Analog To Digital Converters (ADC) Part Context

The AD9644 series includes variants optimized for different sampling rates, such as the AD9644BCPZ-155 which supports up to 155 MSPS. Both variants share the same 48-lead LFCSP package and core architecture but differ in AC performance metrics like SNR and SFDR at higher frequencies. The -80 suffix specifically denotes the 80 MSPS speed bin, ensuring consistent performance for lower bandwidth communication standards.
