HA5023IPZ

Overview

The HA5023IPZ is a dual video current feedback amplifier manufactured by Renesas Electronics Corporation. It operates within an industrial temperature range of -40°C to +85°C and is available in PDIP-8 and SOIC-8 packages. The device features a gain-bandwidth product of 125 MHz and a slew rate of 475 V/µs. Key electrical specifications include an input bias current of 15 µA, an input offset voltage of 3 mV, and an input voltage noise density of 4.5 nV/√Hz. Additional parameters include a common-mode rejection ratio of 53 dB and a power supply rejection ratio of 60 dB.

Feature Summary

• Dual-channel architecture providing two independent video amplifiers in a single package
• Current feedback topology designed for high-speed video signal processing applications
• Industrial operating temperature range suitable for demanding environmental conditions

Applications

• Video signal conditioning circuits
• High-speed data acquisition systems
• Professional video equipment front-ends

Procurement Notes

Verify the specific package variant (PDIP or SOIC) required for the target design, as the suffix indicates the package type. Confirm RoHS compliance status with the supplier, as historical data suggests variations between compliant and non-compliant versions of similar part numbers. Check availability status, as some distributors list this component as limited supply or discontinued. Ensure the ordering code matches the exact pinout and thermal requirements of the application.

Selection Notes

Select this component when a dual-channel solution is required for video bandwidth applications. The current feedback architecture offers superior slew rate performance compared to voltage feedback alternatives at high frequencies. Consider the 125 MHz bandwidth limit for signal fidelity. Evaluate the 475 V/µs slew rate against the maximum frequency and amplitude of the video signals to prevent distortion. Verify that the 15 µA input bias current is acceptable for the source impedance in the circuit design.

Part Context

This component belongs to the HA5023 series of video amplifiers from Renesas Electronics, formerly Intersil. The series is designed for professional video applications requiring high bandwidth and fast transient response. The HA5023IPZ specifically denotes the version with industrial temperature rating and plastic dual in-line or small outline packaging options.

Replacement Considerations

The HA5023IP is a related part number within the same family. Verify if the alternative version meets the specific RoHS compliance and temperature range requirements of the original design before substitution.
