HA9P4905-5

Overview

The HA9P4905-5 is a quad precision analog comparator manufactured by Harris Corporation, part of the HA9P4905 series. It features four independent channels in a single package. The device operates with a supply voltage range from 5 V to 30 V and draws a typical operating current of 20 mA. Key electrical specifications include a maximum input offset voltage of 7.5 mV and an input bias current of 150 nA. The unit provides a response time of 130 ns and functions within a temperature range of 0°C to +75°C.

Feature Summary

• Integrates four high-precision comparators for multi-channel signal processing
• Designed for operation across a wide single-supply voltage range
• Optimized for low input offset voltage and bias current stability

Applications

• Precision voltage monitoring circuits
• Window detector configurations
• Analog-to-digital converter front-end conditioning

Procurement Notes

Verify manufacturer lineage as Harris Corporation assets were acquired by Intersil and subsequently Renesas. Confirm specific suffix requirements for industrial temperature grades. Check datasheet revisions for pinout consistency. Validate RoHS compliance status against current regulatory standards. Ensure sourcing channel provides traceable documentation for quality assurance.

Selection Notes

Select this component when multiple precision comparisons are required in a compact form factor. Consider the 130 ns propagation delay for timing-sensitive applications. Evaluate power consumption constraints given the 20 mA supply current. Compare input offset specifications against system accuracy requirements. Verify package availability matches PCB layout constraints.

Part Context

This device belongs to the HA9P4905 family of quad comparators. It shares functional similarities with other precision comparator ICs but distinguishes itself through specific offset and speed characteristics defined by Harris Corporation design standards. The part represents legacy semiconductor technology adapted for continued use in established industrial designs.
