HA9P4905-5Z

Overview

The HA9P4905-5Z is a quad analog comparator manufactured by Renesas Electronics under the Intersil brand. It features four independent channels housed in a 16-pin SOIC package with surface-mount installation. The device operates within a supply voltage range of 5 V to 30 V and draws a typical operating current of 20 mA. Key electrical specifications include a response time of 130 ns, an input offset voltage of 7.5 mV, and an input bias current of 150 nA. It supports a commercial operating temperature range from 0°C to +75°C.

Feature Summary

• Integrates four precision analog comparators into a single compact package
• Provides high-speed signal comparison with a 130 ns response time
• Operates reliably across a wide single-supply voltage range up to 30 V

Applications

• High-speed data acquisition systems requiring precise voltage threshold detection
• Industrial control circuits utilizing multiple independent signal monitoring channels
• Power supply management units for over-voltage or under-voltage protection logic

Procurement Notes

Verify component authenticity through authorized distributors as this part may be subject to obsolescence. Confirm RoHS compliance status and moisture sensitivity level requirements before procurement. Ensure the SOIC-16 footprint matches your PCB design constraints. Check for available datasheets to validate specific electrical tolerances for your application environment.

Selection Notes

Select this component when multiple independent comparison functions are required in a space-constrained design. Consider the 130 ns propagation delay for timing-sensitive applications. Evaluate the 7.5 mV offset voltage against system accuracy requirements. Ensure the 30 V maximum supply rating aligns with the target circuit's power distribution network.

Part Context

This device belongs to the HA9P4905 series of analog comparators produced by Renesas/Intersil. It serves as a multi-channel solution for signal processing tasks where discrete comparators would increase board complexity. The SOIC-16 packaging facilitates automated assembly processes while maintaining electrical performance suitable for commercial-grade electronics.
