AD9228ABCPZRL7-65

Overview

The AD9228ABCPZRL7-65 is a quad, 12-bit analog-to-digital converter (ADC) operating at sampling rates up to 65 MSPS. It integrates four pipeline ADCs with on-chip sample-and-hold circuits in a single package. The device features a 315 MHz full-power analog bandwidth and accepts a 2 V p-p differential input voltage range. It operates from a single 1.8 V supply and utilizes serial LVDS outputs compliant with ANSI-644 standards. Key performance metrics include an SNR of 70 dB, an ENOB of 11.3 bits, and an SFDR of 82 dBc at Nyquist frequencies.

Feature Summary

• Integrates four independent 12-bit ADC channels within a compact footprint for space-constrained designs.
• Provides flexible bit orientation and programmable clock/data alignment via serial port interface control.
• Includes built-in digital test pattern generation capabilities supporting deterministic, pseudorandom, and user-defined codes.
• Supports individual channel power-down modes to minimize system power consumption when not in use.

Applications

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

Procurement Notes

Verify the specific ordering suffix RL7 against official documentation to confirm tape and reel packaging requirements. Ensure the component matches the intended speed grade and pinout configuration before procurement. Cross-reference the manufacturer's current datasheet revision to validate all electrical specifications and absolute maximum ratings.

Selection Notes

Select this component for applications requiring high dynamic performance with low power dissipation per channel. Consider the 48-lead LFCSP package dimensions for PCB layout constraints. Evaluate the need for external reference components based on the internal 1.0 V reference availability and load regulation specifications.

Part Context
