HA5024IPZ

Overview

The HA5024IPZ is a quad video current feedback amplifier manufactured by Renesas Electronics Corporation. It features a wide unity gain bandwidth of 125 MHz and a high slew rate of 475 V/µs, optimized for video applications with gains between 1 and 10. The device includes an individual output enable/disable function that significantly reduces supply current while forcing the output to a true high impedance state. It operates within a temperature range of -40°C to +85°C and is housed in a 20-lead PDIP package.

Feature Summary

• Quad current feedback architecture providing superior bandwidth stability at higher closed-loop gains compared to voltage feedback amplifiers.
• Individual output enable and disable control for each channel, allowing implementation of video multiplexers with reduced power consumption.
• Low differential gain and phase distortion characteristics suitable for demanding video signal processing.
• High slew rate and wide bandwidth performance optimized for video gain blocks and distribution amplifiers.

Applications

• Video multiplexers and switching routing systems
• Video gain blocks and distribution amplifiers
• RGB amplifiers and flash A/D drivers
• Medical imaging and radar imaging systems

Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to obsolescence. Confirm RoHS compliance status and Pb-free anneal specifications required for wave soldering processes only. Ensure ordering suffixes match exact package and environmental requirements specified in official documentation.

Selection Notes

Select based on current feedback topology requirements where bandwidth independence from closed-loop gain is critical. Evaluate thermal dissipation capabilities for quad amplifier configurations under maximum ambient temperatures. Consider the disable pin drive requirements for logic compatibility when implementing multiplexer functions.

Part Context

The HA5024 serves as the quad version of the Intersil HA5020 single amplifier. It belongs to the HA5024 series of high-speed video amplifiers designed by Renesas Electronics Corporation. The device represents a specialized solution for multi-channel video signal processing requiring precise timing and low distortion characteristics.

Replacement Considerations

Public datasheets identify the HA5023 as the recommended replacement part for new designs. Verify functional compatibility and pinout alignment before substitution.

FAQ

How does the disable function operate?

Pulling the disable pin low sinks current to force the output into a true high impedance state and significantly reduces supply current. Leaving the pin floating enables the amplifier via internal pull-up resistors.

What is the optimal feedback resistor value?

The design is optimized for a 1000Ω feedback resistor (RF) at a gain of +1. Decreasing RF can increase bandwidth at higher gains but may affect stability.
