ADA4310-1ARHZ-RL

Overview

The ADA4310-1ARHZ-RL is a dual-channel, high-speed current feedback operational amplifier designed for broadband applications requiring high linearity and low impedance load driving. It features a 190 MHz bandwidth at G = +5 and an 820 V/µs slew rate. The device supports single (+5 V to +12 V) or dual (±2.5 V to ±6 V) supplies within the -40°C to +85°C range. Integrated power management allows four modes via CMOS-compatible PD1/PD0 pins, reducing quiescent current to 0.65 mA per amplifier in shutdown.

Feature Summary

• Dual high-speed current feedback amplifiers optimized for broadband signal processing with high output current capability.
• Integrated power management system enabling full, medium, low power, and complete shutdown states via logic control pins.
• Thermally enhanced 10-lead MSOP package design with exposed paddle for improved heat dissipation and ground reference.

Applications

• Home networking line drivers
• Twisted pair line drivers
• Power line communications
• Video line drivers

Procurement Notes

Verify that the ordering suffix '-RL' corresponds to the reel packaging format specified in the manufacturer's official documentation. Confirm the 'Z' suffix indicates RoHS compliance status as defined by Analog Devices. Ensure the component matches the 10-lead Mini Small Outline Package with Exposed Pad (RH-10-1) physical dimensions and pinout configuration before integration into the PCB layout.

Selection Notes

Select this component when designing circuits requiring high output current drive capabilities alongside wide bandwidth performance. The integrated power-down functionality makes it suitable for battery-operated systems where optimizing quiescent current consumption is critical. Verify that the application environment remains within the specified industrial temperature range of -40°C to +85°C for reliable operation.

FAQ

How does the exposed thermal pad function in the 10-lead MSOP package?

In the 10-lead MSOP package, the exposed thermal pad must be connected to ground. It serves as both the electrical reference for the power-down pins and the sole connection point for the negative supply voltage, restricting the device to single-supply operation.

What are the specific logic levels required for the power-down control pins?

The PD1 and PD0 pins are CMOS level compatible. A threshold of 1.5 V referenced to ground determines the state, allowing control using standard 3 V and 5 V CMOS logic signals to switch between power modes.
