AD9640BCPZ-80

Analog To Digital Converters (ADC) Overview

The AD9640BCPZ-80 is a dual-channel, 14-bit analog-to-digital converter (ADC) from Analog Devices. It operates at a maximum sampling rate of 80 MSPS with a differential pipelined architecture and integrated output error correction logic. The device requires a single 1.8 V analog supply (AVDD/DVDD) and supports digital output driver supplies (DRVDD) ranging from 1.8 V to 3.3 V for CMOS or 1.8 V for LVDS modes. Key performance metrics include an SNR of 72.5 dB at 2.3 MHz input frequency and an SFDR of 87 dBc under the same conditions. It features flexible analog inputs with a bandwidth of 650 MHz and includes internal voltage references and sample-and-hold circuits.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BCPZ' against the manufacturer's current ordering guide to confirm package type and temperature grade specifications. Ensure that the required sampling rate aligns with the '-80' designation, as other variants in the family support higher speeds. Confirm interface compatibility with the target system's digital logic levels before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a dual-channel 14-bit resolution is required at sampling rates up to 80 MSPS. Consider the AD9640BCPZ-80 for designs needing integrated AGC support via fast detect and signal monitor features. Evaluate the power consumption requirements, noting that standby and power-down modes are available. Ensure the PCB layout accommodates the 64-lead LFCSP package and provides adequate thermal dissipation for the exposed paddle.

Analog To Digital Converters (ADC) Part Context

The AD9640BCPZ-80 belongs to the AD9640 family of high-speed, low-power dual ADCs. This family shares pinout compatibility with the AD9627, AD9627-11, and AD9600, facilitating migration between different resolution and speed grades. The device is designed to replace older generation converters while offering improved dynamic range and lower power consumption in a compact form factor suitable for modern communication infrastructure.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives within the same family include the AD9640ABCPZ-80, which may differ in performance grading or temperature range. For migration from lower resolutions, the AD9627 series offers a compatible footprint. Verify that any substitute maintains the required 14-bit resolution and 80 MSPS sampling capability.
