AD9219BCPZ-40

Overview

The AD9219BCPZ-40 is a quad, 10-bit analog-to-digital converter (ADC) operating at a maximum sampling rate of 40 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 from a single 1.8 V supply. Key electrical specifications include a differential input voltage range of 2 V p-p, an analog bandwidth of 315 MHz, and typical linearity performance with DNL of ±0.4 LSB and INL of ±0.4 LSB. Total power dissipation is specified at 295 mW to 378 mW depending on conditions.

Feature Summary

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

Applications

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

Procurement Notes

Verify the specific suffix designation against official documentation to confirm the 40 MSPS speed grade. Ensure that the LFCSP-48 package requirements and exposed pad grounding are addressed during procurement planning. Confirm RoHS compliance status through the manufacturer's current product release notes before finalizing orders.

Selection Notes

Select this component when a multi-channel solution is required without increasing board space. The 40 MSPS speed grade is suitable for applications where lower data throughput reduces system complexity compared to the 65 MSPS variant. Consider the serial LVDS interface compatibility with downstream processing logic and verify that the 1.8 V supply rails align with the system power architecture.

Part Context

This part belongs to the AD9219 family of high-speed, low-power quadruple ADCs. It shares pinout and functional similarities with other members like the AD9287, AD9228, and AD9259, which offer different resolution options. The BCPZ-40 suffix specifically denotes the 40 MSPS operational speed grade within the industrial temperature range.

Replacement Considerations

The AD9219ABCPZ-40 is a documented alternative within the same series offering similar quad-channel functionality. Verify if the A-grade specifications meet the design requirements. Other family members such as the AD9287 or AD9228 provide pin-compatible alternatives with varying resolutions.
