AD9219ABCPZ-65

Overview

The AD9219ABCPZ-65 is a quad, 10-bit analog-to-digital converter (ADC) operating at a maximum sampling rate of 65 MSPS. It integrates four pipeline ADCs with on-chip sample-and-hold circuits in a single package. The device utilizes a serial LVDS interface for data output and operates on a single 1.8 V supply. Key electrical specifications include a full-power analog bandwidth of 315 MHz, a differential input voltage range of 2 V p-p, and a typical signal-to-noise ratio (SNR) of 60.2 dB. Power consumption reaches up to 378 mW total, with individual channel power dissipation at 94 mW per channel during operation.

Feature Summary

• Integrates four independent 10-bit ADC channels within a compact LFCSP-48 package.
• Features a serial LVDS digital output interface with programmable clock and data alignment.
• Supports flexible bit orientation and built-in digital test pattern generation via SPI control.
• Includes individual-channel power-down modes to minimize standby power consumption.

Applications

• Medical imaging and nondestructive ultrasound systems
• Portable ultrasound and digital beam-forming applications
• Quadrature and diversity radio receivers
• Optical networking equipment
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix -65 indicates the 65 MSPS speed grade when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the LFCSP-48 package thermal requirements are met during PCB design. Check for availability of the AD9219-65EBZ evaluation board for system validation prior to final procurement.

Selection Notes

Select this component for designs requiring four synchronized high-speed channels in a small footprint. Compare against the AD9219-40 variant if a lower 40 MSPS sampling rate suffices for the application. Consider the pin-compatible AD9287, AD9228, and AD9259 if different resolution options are needed. Ensure the system can accommodate the 1.8 V supply requirement and LVDS signaling constraints.

Part Context

The AD9219 series belongs to Analog Devices' portfolio of low-power, high-speed data converters. It is designed for applications where space and power efficiency are critical alongside dynamic performance. The device family includes variants with different sampling rates and resolutions, sharing a common pinout and functional architecture to simplify design transitions across product lines.

Replacement Considerations

The AD9219ABCPZ-40 serves as a direct pin-compatible alternative with a reduced 40 MSPS sampling rate. Other members of the pin-compatible family include the AD9287 (8-bit), AD9228 (12-bit), and AD9259 (14-bit). Verify that any substitute meets the required SNR, linearity, and power specifications for the specific application.

FAQ

What is the default digital output coding format?

The default output coding format is offset binary.

Does the AD9219 require an external voltage reference?

No external reference is required for many applications as it features an internal reference, though external references can be used via the REFT/REFB pins.

How is the data clock generated for the output interface?

The ADC automatically multiplies the sample rate clock to generate the appropriate LVDS serial data rate, providing a dedicated Data Clock Output (DCO).
