AD9051BRSZ-2V

Overview

The AD9051BRSZ-2V is a 10-bit, 60 MSPS monolithic sampling analog-to-digital converter (ADC) fabricated on a BiCMOS process. It integrates an onboard track-and-hold circuit and a 2.5 V voltage reference, requiring only a single 5 V supply for operation. The device features a selectable input bandwidth of 50 MHz or 130 MHz via the BWSEL pin. Digital outputs are CMOS compatible with either 5 V or 3 V logic levels through isolated VDD pins. It operates within an industrial temperature range of –40 °C to +85 °C.

Feature Summary

• Integrates a high-speed differential analog input buffer with internal biasing at 2.5 V.
• Employs a two-step subranging architecture with digital error correction for true 10-bit accuracy.
• Provides latched parallel digital outputs with five pipeline delays relative to the encode clock.
• Includes an out-of-range comparator that locks digital outputs to maximum or minimum values during overdrive.

Applications

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

Procurement Notes

Verify the specific ordering suffix to confirm package type and reel configuration. Ensure the component matches the required RoHS compliance status indicated by the Z suffix. Confirm the temperature grade corresponds to the industrial range specifications. Validate the pinout compatibility with the target PCB footprint before integration.

Selection Notes

Select this model when a complete 10-bit ADC solution with integrated timing and reference is required. Choose the BRS-2V variant if specific input coding options or gain control adjustments are needed. Consider the 3 V logic interface capability to reduce system power consumption in low-voltage environments. Evaluate the 50 MHz versus 130 MHz bandwidth settings based on the Nyquist requirements of the signal chain.

Part Context

This component belongs to the AD9051 family of high-speed data converters from Analog Devices. It utilizes a subranging architecture optimized for dynamic performance while maintaining low power dissipation. The device is designed for applications demanding cost-effective, high-performance analog-to-digital conversion without external support components.

Replacement Considerations

Direct substitutes include other models within the AD9051 series such as the AD9051BRS or AD9051BRSRL. Verify pinout and electrical specifications match before substitution. Cross-referencing with similar 10-bit, 60 MSPS ADCs may require additional interface adaptation.
