AD9228ABCPZ-40

Overview

The AD9228ABCPZ-40 is a quad, 12-bit analog-to-digital converter (ADC) operating at a maximum sampling rate of 40 MSPS. It integrates four independent ADCs within a single package to minimize footprint and power consumption. The device features a 315 MHz full-power analog bandwidth and accepts a 2 V p-p differential input voltage range. It operates on a single 1.8 V supply and utilizes serial LVDS outputs compliant with ANSI-644 standards. Key performance metrics include a signal-to-noise ratio (SNR) of 70 dB, an effective number of bits (ENOB) of 11.3 bits, and a spurious-free dynamic range (SFDR) of 82 dBc up to the Nyquist frequency. Differential nonlinearity (DNL) is typically ±0.3 LSB, while integral nonlinearity (INL) is typically ±0.4 LSB.

Feature Summary

• Integrates four 12-bit ADC channels in a compact LFCSP package for space-constrained designs.
• Provides flexible bit orientation and programmable clock/data alignment via SPI control.
• Includes built-in digital test pattern generation capabilities for system verification.
• Supports individual channel power-down modes to reduce overall system energy usage.

Applications

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

Procurement Notes

Verify the specific suffix 'ABCPZ' against the manufacturer's current ordering guide to confirm pinout compatibility and RoHS compliance status. Ensure that the selected package variant matches the required thermal dissipation characteristics for the intended operating environment. Cross-reference the datasheet revision history to validate any recent updates to electrical specifications or absolute maximum ratings before finalizing procurement orders.

Selection Notes

Select this component when a high-density solution requiring four synchronized 12-bit conversion channels is necessary. The AD9228ABCPZ-40 is appropriate for systems prioritizing low power consumption alongside moderate-speed data acquisition requirements up to 40 MSPS. Consider the integrated sample-and-hold circuit and internal reference options to simplify external driver design and reduce bill-of-materials complexity.

Part Context

This part belongs to the AD9228 family of quad-channel ADCs, which also includes variants optimized for different sampling rates such as the AD9228-65. The product line shares a common pinout architecture with other members like the AD9287, AD9219, and AD9259, facilitating potential upgrades or downgrades in resolution without redesigning the PCB layout.

Replacement Considerations

Direct substitutes within the same family include the AD9228-65 for higher speed requirements. Other pin-compatible alternatives from Analog Devices include the AD9287, AD9219, and AD9259, which offer varying resolutions while maintaining the same physical interface constraints.
