AD9051BRSZRL

Overview

The AD9051BRSZRL is a 10-bit monolithic sampling analog-to-digital converter (ADC) from Analog Devices, packaged in a 28-lead Shrink Small Outline Package (SSOP). It operates at a maximum sampling rate of 60 MSPS with a total power dissipation of 250 mW. The device features an onboard track-and-hold circuit and a 2.5 V voltage reference. It supports selectable input bandwidths of 50 MHz or 130 MHz via the BWSEL pin. The ADC accepts single-ended or differential analog inputs within a nominal range of 1.875 V to 3.125 V. Digital outputs are CMOS compatible with 5 V or 3 V logic supplies. The component functions over an industrial temperature range of –40 °C to +85 °C.

Feature Summary

• Integrates a high-speed track-and-hold amplifier and a stable internal 2.5 V bandgap voltage reference on a single chip.
• Utilizes a two-step subranging architecture with digital error correction to ensure true 10-bit accuracy.
• Provides configurable input bandwidth selection between 50 MHz and 130 MHz for optimized dynamic performance.
• Supports flexible logic interfacing with isolated digital supply pins allowing direct connection to 3 V or 5 V systems.

Applications

• Medical Imaging
• Digital Communications
• Professional Video
• Instrumentation
• Set-Top Box

Procurement Notes

Verify the specific ordering suffix RL indicates reel packaging when sourcing this component. Confirm RoHS compliance status associated with the Z suffix if environmental regulations apply to the target assembly. Ensure the supplier provides valid traceability documentation for the Analog Devices manufacturer part number. Check for any obsolescence notices as older revisions may have different availability profiles.

Selection Notes

Select this model for applications requiring a balance of low power consumption and high-speed conversion. The integrated reference simplifies board design by reducing external component count. Consider the 3 V logic interface option to minimize system power dissipation in output stages. Verify that the selected input bandwidth setting matches the signal frequency requirements for optimal SNR performance.

Part Context

This component belongs to the AD9051 family of 10-bit, 60 MSPS A/D converters. It shares architectural similarities with other members like the AD9050 and AD9057 but offers specific pinout and feature configurations. The SSOP package provides a space-saving surface mount solution compared to larger leaded packages. It is designed for cost-effective, high-performance data acquisition systems.

Replacement Considerations

Direct functional substitutes within the same family include the AD9051BRS and AD9051BRS-2V. For dual-channel requirements, consider the AD9059 series. Verify pin compatibility and logic voltage levels before substituting with other ADC models from different manufacturers.
