CLC440AJP

Overview

The CLC440AJP is a high-speed, low-power voltage feedback operational amplifier manufactured by National Semiconductor. It features a unity-gain bandwidth of 750MHz and a slew rate of 1500V/µs. The device provides an output current of 90mA while dissipating only 70mW of power. It exhibits differential gain error of 0.015% and differential phase error of 0.025°. Input noise specifications are 3.5nV/√Hz for voltage and 2.5pA/√Hz for current. The component operates with wide dual or single supply ranges.

Feature Summary

• Integrates current feedback properties such as high bandwidth and fast slewing into a classical voltage feedback architecture
• Features truly differential and fully symmetrical inputs with high impedance and matched low bias currents
• Does not require a specific feedback resistor for stability, allowing flexibility in wideband filtering and integration designs
• Supports operation with a wide range of dual or single power supplies

Applications

• Video signal processing applications requiring low differential gain and phase errors
• Wideband filtering circuits
• Integration circuits utilizing flexible feedback resistor selection

Procurement Notes

Verify the manufacturer designation, as National Semiconductor assets were acquired by Texas Instruments. Confirm the package type corresponds to the AJP suffix, typically indicating a plastic DIP configuration. Ensure the datasheet version matches the specific revision for electrical characteristics. Check for availability through authorized distributors or secondary market suppliers like Rochester Electronics if direct manufacturing support has transitioned.

Selection Notes

Select this component when high-speed voltage feedback performance is required without the constraints of fixed feedback resistors typical in current feedback amplifiers. The low power dissipation makes it suitable for battery-operated or thermally constrained systems. Consider the input impedance and noise levels for precision analog signal conditioning tasks where wide bandwidth is critical.

Part Context

The CLC440 series represents a hybrid design combining the speed of current feedback amplifiers with the ease of use of voltage feedback topologies. Originally developed by Comlinear and later produced by National Semiconductor, these devices target professional video and broadband communication markets. The AJP variant specifically denotes the package style used for prototyping and general purpose circuit implementation.
