ADA4311-1ARHZ-RL

Overview

The ADA4311-1ARHZ-RL is a dual high-speed current feedback operational amplifier manufactured by Analog Devices Inc. It features a -3 dB bandwidth of 310 MHz and a slew rate of 1050 V/µs at G = +5 with a 50 Ω load. The device supports a single supply voltage range of 6 V to 12 V, drawing up to 11.8 mA per amplifier in full power mode. It provides a differential output swing of 20.6 V p-p into a 100 Ω load. The unit is housed in a thermally enhanced 10-lead MSOP package with an exposed paddle for improved thermal conduction.

Feature Summary

• Dual high-speed current feedback architecture optimized for driving low impedance loads with high linearity.
• Integrated power management allowing four selectable modes: full power, medium power, low power, and complete shutdown via CMOS-compatible control pins.
• Thermally enhanced 10-lead MSOP package design with an exposed ground paddle to facilitate efficient heat dissipation.

Applications

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

Procurement Notes

Verify the specific ordering suffix matches the required packaging format, as the datasheet lists multiple variants including tape and reel options. Confirm RoHS compliance status indicated by the Z suffix. Ensure the procurement request aligns with the manufacturer's standard lead times and minimum order quantities defined by the distributor or direct sales channels.

Selection Notes

Select this component for broadband applications requiring high output current and fast transient response. The device is suitable for designs needing adjustable quiescent current consumption to balance performance against power efficiency. Verify that the application circuit utilizes the recommended feedback resistor values to maintain stability and achieve the specified bandwidth characteristics.

Part Context

This part belongs to the ADA4311-1 series of dual current feedback amplifiers from Analog Devices. It is designed specifically for line driver applications where high speed and low distortion are critical. The series includes variations in packaging and reel configurations, all sharing the same core electrical specifications and pinout compatibility within the industrial temperature range.

Replacement Considerations

Direct substitutes include other models within the ADA4311-1 family such as the ADA4311-1ARHZ or ADA4311-1ARHZ-R7, which share identical electrical characteristics and pin configurations but may differ in shipping packaging formats.
