AD9253BCPZRL7-125

Overview

The AD9253BCPZRL7-125 is a quad, 14-bit analog-to-digital converter (ADC) with an on-chip sample-and-hold circuit. It operates at conversion rates up to 125 MSPS and requires a single 1.8 V power supply. The device features serial LVDS outputs, a 650 MHz full-power analog bandwidth, and a 2 V p-p input voltage range. It includes programmable output clock and data alignment, built-in digital test pattern generation, and individual channel power-down modes. The component is housed in a RoHS-compliant 48-lead LFCSP package and is specified over the industrial temperature range of −40°C to +85°C.

Feature Summary

• Quad-channel architecture with integrated sample-and-hold circuitry for high-density applications.
• Low power consumption with scalable options and individual channel power-down capabilities.
• Flexible bit orientation and programmable output resolution via serial port interface.
• Built-in deterministic and pseudorandom digital test pattern generation.

Applications

• Medical ultrasound systems
• High-speed imaging equipment
• Quadrature and diversity radio receivers
• Test and measurement devices

Procurement Notes

Verify that the specific ordering suffix matches the required reel packaging configuration. Confirm the exact speed grade variant corresponds to the system timing requirements. Ensure the component source is authorized to guarantee authenticity and adherence to the manufacturer's quality standards.

Selection Notes

Select this model when four synchronized 14-bit channels are required within a compact footprint. Evaluate the 125 MSPS speed grade against the maximum signal frequency to ensure adequate Nyquist coverage. Consider the low power profile if thermal management or battery operation is a primary design constraint.

Part Context

This component belongs to the AD9253 family of high-performance analog-to-digital converters. It shares pin compatibility with the AD9633 12-bit quad ADC, facilitating potential design upgrades or replacements. The series is optimized for applications demanding outstanding dynamic performance alongside minimal physical size.

Replacement Considerations

The AD9633 is a pin-compatible alternative offering 12-bit resolution. Verify that the reduction in resolution meets the system accuracy requirements before substituting.
