AD9228ABCPZRL7-40

Overview

The AD9228ABCPZRL7-40 is a quad, 12-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 requires a single 1.8 V power supply and accepts LVPECL, CMOS, or LVDS-compatible clock signals. It features serial LVDS outputs compliant with ANSI-644 standards. Key performance metrics include a signal-to-noise ratio (SNR) of 70 dB to Nyquist, an effective number of bits (ENOB) of 11.3 bits, and a spurious-free dynamic range (SFDR) of 82 dBc. Differential nonlinearity (DNL) is typically ±0.3 LSB, while integral nonlinearity (INL) is typically ±0.4 LSB. The component operates within an industrial temperature range of −40°C to +85°C.

Feature Summary

• Integrates four independent 12-bit ADC channels within a compact footprint.
• Supports flexible clock input compatibility including LVPECL, CMOS, and LVDS.
• Provides programmable digital test pattern generation via serial port interface.
• Includes dedicated data clock output (DCO) and frame clock output (FCO).

Applications

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

Procurement Notes

Verify the specific suffix L7-40 against the manufacturer's current ordering guide to confirm reel packaging and 40 MSPS speed grade. Ensure the source document explicitly lists this exact part number variant. Confirm RoHS compliance status through official documentation rather than distributor summaries.

Selection Notes

Select this component when a system requires four simultaneous 12-bit conversion channels with low power consumption. The 40 MSPS speed grade is suitable for applications where bandwidth requirements are moderate. Consider the pin-compatible AD9219 if 10-bit resolution suffices, or the AD9259 for higher 14-bit precision needs.

Part Context

This part belongs to the AD9228 family of quad-channel ADCs from Analog Devices. It shares the same physical package and pinout as other variants in the series, such as the AD9228-65, which supports up to 65 MSPS. The family is designed for space-constrained applications requiring multiple high-speed conversions.

Replacement Considerations

The AD9228-65 is a pin-compatible alternative offering a higher 65 MSPS sampling rate. For lower resolution requirements, the AD9219 provides a 10-bit option. For higher resolution, the AD9259 offers 14-bit performance within the same package.
