ADA4311-1ARHZ-R7

Overview

The ADA4311-1ARHZ-R7 is a dual high-speed current feedback operational amplifier in a 10-lead MSOP package with an exposed thermal pad. It features a 310 MHz bandwidth and 1050 V/µs slew rate at G=+5. The device supports single-supply operation from 6 V to 12 V, delivering up to 20.6 V p-p differential output swing into 100 Ω loads. Integrated power management allows four modes via CMOS-compatible PD1/PD0 pins, reducing quiescent current to 1 mA/amplifier in shutdown.

Feature Summary

• Dual high-speed current feedback amplifiers optimized for driving low impedance loads with high linearity
• Integrated power management enabling full, medium, low power, and complete shutdown modes
• CMOS-compatible control inputs for selectable quiescent current optimization
• Thermally enhanced 10-lead MSOP package with exposed paddle for improved heat dissipation

Applications

• Home networking line drivers
• Twisted pair line drivers
• Power line communications (PLC)
• Video line drivers
• ARB line drivers

Procurement Notes

Verify the specific ordering suffix R7 indicates reel packaging when sourcing components. Confirm RoHS compliance status as indicated by the Z suffix in the base part number ADA4311-1ARHZ. Ensure the supply voltage range of 6 V to 12 V matches system requirements. Check that the operating temperature range of -40°C to +85°C fits the application environment. Validate pinout compatibility for the 10-lead MSOP-EP package during integration.

Selection Notes

Select this component for broadband applications requiring high output current and fast transient response. The current feedback architecture provides consistent bandwidth across various gain settings. Consider the exposed thermal pad requirement for proper grounding and heat sinking. Evaluate the power-down functionality if energy efficiency is critical. Ensure PCB layout adheres to high-speed design guidelines to minimize parasitic effects.
