AD9051BRSRL-2V

Overview

The AD9051BRSRL-2V is a 10-bit, 60 MSPS monolithic sampling analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It features an onboard track-and-hold circuit and voltage reference, requiring only a single 5 V supply and an encode clock for operation. The device offers selectable input bandwidths of 50 MHz or 130 MHz via the BWSEL pin. It achieves 9.3 effective number of bits at an input frequency of 10.3 MHz with total power dissipation of 250 mW at maximum sampling rate. The component supports both 5 V and 3 V logic I/O compatibility and is packaged in a 28-lead shrink small outline package (SSOP).

Feature Summary

• Integrated track-and-hold and voltage reference circuits eliminate external component requirements.
• Selectable input bandwidth configuration allows optimization for specific signal frequencies.
• Dual voltage logic interface supports direct connection to both 5 V and 3 V digital systems.
• Out-of-range detection clamps digital outputs to prevent invalid data during signal overdrive.

Applications

• Medical imaging systems
• Digital communications infrastructure
• Professional video processing equipment
• General instrumentation applications

Procurement Notes

Verify the ordering suffix RL indicates reel packaging when sourcing components. Confirm RoHS compliance status through the Z suffix if required by assembly specifications. Ensure the -2V variant matches the intended analog input coding requirements. Cross-reference the manufacturer's latest datasheet revision to confirm pinout consistency before finalizing procurement orders.

Selection Notes

Select this model for applications requiring high dynamic performance with low power consumption. The -2V suffix specifies distinct digital output coding compared to standard versions. Evaluate the need for external reference voltage if higher accuracy than the internal 2.5 V bandgap is necessary. Consider the 28-lead SSOP package dimensions for PCB layout constraints.

Part Context

This component belongs to the AD9051 family of 10-bit ADCs from Analog Devices. It utilizes a subranging architecture with digital error correction to ensure true 10-bit accuracy. The device is fabricated on a BiCMOS process and operates within the industrial temperature range of –40°C to +85°C. It serves as a cost-effective solution for medium-speed, high-resolution data acquisition tasks.

Replacement Considerations

The AD9051BRSZ-2V is a RoHS-compliant version of the same functional device. Verify pin compatibility and electrical specifications before substituting non-RoHS parts. No direct cross-manufacturer equivalents are documented in the official datasheet.
