AD9051BRSRL

Overview

The AD9051BRSRL is a 10-bit monolithic sampling analog-to-digital converter (ADC) operating at a maximum sampling rate of 60 MSPS. It features an onboard track-and-hold circuit and a 2.5 V voltage reference, requiring only a single 5 V supply and an encode clock for operation. The device delivers 9.3 effective number of bits (ENOB) at an input frequency of 10.3 MHz with total power dissipation of 250 mW at full speed. Users can select between a nominal 50 MHz or 130 MHz input bandwidth via the BWSEL pin. Digital I/O supports both 5 V and 3 V logic levels, and the component is housed in a 28-lead shrink small outline package (SSOP).

Feature Summary

• Integrates a high-speed differential analog input buffer with internal biasing to simplify signal conditioning.
• Employs a two-step subranging architecture with digital error correction to ensure true 10-bit accuracy.
• Includes overdrive protection that clamps the input buffer and locks digital outputs when signals exceed nominal ranges.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and compliance status. The 'RL' suffix indicates reel packaging, while 'Z' denotes RoHS compliance. Ensure the selected variant matches the required temperature range and pin configuration for the target design.

Selection Notes

Select this component for applications requiring low power consumption and high dynamic performance from a single supply. Consider the selectable input bandwidth feature if system requirements vary between narrow and wideband signal processing. Verify that the 3 V or 5 V logic interface aligns with the downstream FPGA or processor capabilities.

Part Context

The AD9051BRSRL belongs to the AD9051 family of 10-bit, 60 MSPS ADCs manufactured by Analog Devices. This series utilizes a BiCMOS process to achieve high performance in a compact SSOP package. The BRSRL designation specifically identifies the industrial temperature range version supplied in tape and reel format.

Replacement Considerations

The AD9051-2V is a compatible variant within the same family offering different input coding options. Other models such as the AD9050 provide similar functionality with potentially different sampling rates or resolution characteristics.
