Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix matches the required package type, as the base part number supports multiple configurations including tape and reel options. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure the selected variant aligns with the intended PCB layout constraints for the SO-8 footprint.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring wide bandwidth without gain-dependent frequency roll-off. Consider the enable pin functionality if system power conservation is critical. Evaluate the feedback resistor value carefully, as it dictates the closed-loop bandwidth and stability rather than the gain setting alone. Verify that the supply voltage range accommodates the required output swing and current drive capabilities.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the NCS2502 series of high-speed current feedback amplifiers manufactured by onsemi. It is designed to replace legacy parts like the EL5160 and MAX4452 while offering modern features such as an integrated enable control. The series targets demanding analog signal paths where speed and linearity are paramount.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The datasheet confirms pin compatibility with the EL5160 and MAX4452. Designers should verify that external circuit components, particularly feedback resistors, are adjusted to match the specific bandwidth requirements of these alternative devices.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the enable pin affect the device's power consumption?

When the enable pin is driven low, the device enters a disabled state, reducing the supply current from approximately 650 µA to less than 40 µA.

What determines the bandwidth of this current feedback amplifier?

Unlike voltage feedback amplifiers, the bandwidth is primarily determined by the value of the external feedback resistor rather than the closed-loop gain.

Is the NCS2502DG available in lead-free packages?

Yes, the datasheet indicates that Pb-Free packages are available for this device.
