AD9219ABCPZ-40

Overview

The AD9219ABCPZ-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 a typical signal-to-noise ratio (SNR) of 61.2 dB. Linearity performance features a typical differential nonlinearity (DNL) of ±0.2 LSB and integral nonlinearity (INL) of ±0.3 LSB. The component is housed in a 48-lead LFCSP package and supports operation across the industrial temperature range of −40°C to +85°C.

Procurement Notes

Verify the specific suffix designation against official documentation to confirm the 40 MSPS speed grade and packaging configuration. Ensure that the ordering information matches the required RoHS compliance status and lead finish specifications defined by the manufacturer for this particular part number variant.

Selection Notes

Select this component when a low-power, multi-channel solution is required for high-speed data acquisition. The integrated reference and driver requirements simplify design complexity compared to discrete solutions. Consider the available development tools, such as evaluation boards, to validate system performance during the initial design phase.

Part Context

This device belongs to the AD9219 family of quad ADCs, which also includes variants optimized for different sampling rates and resolutions. The family shares pin compatibility with other members like the AD9287, AD9228, and AD9259, facilitating design scalability across different resolution and speed requirements within the same product line.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the AD9219 series, such as the AD9219ABCPZ-65. Designers should verify that the alternative part meets the specific sampling rate and dynamic performance requirements of the application.
