ADA4310-1ACPZ-R7

Overview

The ADA4310-1ACPZ-R7 is a dual 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, an 820 V/µs slew rate, and a differential output swing of 20.4 V p-p from a 12 V supply. The device operates on single or dual supplies ranging from +5 V to ±6 V with adjustable quiescent currents between 3.9 mA and 7.6 mA per amplifier. It includes CMOS-compatible power-down control pins (PD1, PD0) enabling four operating modes, reducing standby current to 0.65 mA per amplifier.

Feature Summary

• Dual high-speed current feedback amplifiers optimized for broadband signal processing and high linearity performance.
• Integrated power management system allowing selection among full power, medium power, low power, and complete shutdown states via logic inputs.
• High output drive capability supporting large differential voltage swings across low impedance loads.

Applications

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

Procurement Notes

Verify the specific package variant against the ordering guide, as the ACPZ suffix denotes the 16-lead LFCSP form factor. Confirm that the exposed thermal pad connection requirements align with the target PCB layout design. Ensure power supply decoupling capacitors are placed within the specified distance to maintain stability and minimize ripple effects during operation.

Selection Notes

Select this component when designing circuits that require high slew rates and wide bandwidths for driving low impedance transmission lines. Evaluate the trade-off between bandwidth and gain settings using the recommended feedback resistor values provided in the datasheet. Consider the available power modes to optimize thermal dissipation and total system power consumption based on the active duty cycle requirements.
