AD9649BCPZ-80

Analog To Digital Converters (ADC) Overview

The AD9649BCPZ-80 is a monolithic, single-channel 14-bit analog-to-digital converter (ADC) from Analog Devices. It operates at a maximum sampling rate of 80 MSPS with a differential input bandwidth of 700 MHz. The device utilizes a multistage differential pipeline architecture with output error correction logic to ensure no missing codes across the full operating temperature range. It features an on-chip voltage reference and sample-and-hold circuit, supporting a 2 V p-p differential analog input span. Power consumption is specified at 87 mW at 80 MSPS with a 1.8 V analog supply. The component is housed in a 32-lead LFCSP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BCPZ' against the manufacturer's official ordering guide to confirm pinout compatibility and RoHS compliance status. Ensure that the required thermal management strategy accounts for the exposed paddle ground connection requirements specified in the datasheet. Confirm that the DRVDD supply voltage matches the receiving logic family before integration.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a 14-bit resolution and 80 MSPS throughput are required within a compact form factor. The device supports integer clock dividers of 1, 2, or 4, allowing flexibility in system clock design. Consider the separate DRVDD supply option if interfacing with 3.3 V logic families is necessary while maintaining low analog power consumption.

Analog To Digital Converters (ADC) Part Context

This component belongs to the AD9649 series, which includes variants operating at 20, 40, and 65 MSPS. The AD9649 is pin-compatible with the AD9629 (12-bit) and AD9609 (10-bit) ADCs, facilitating migration paths between different resolution levels without redesigning the PCB layout.
