ISL55004IB

Overview

The ISL55004IB is a quad voltage feedback operational amplifier manufactured by Intersil. It features a gain-bandwidth product of 70 MHz and a high slew rate of 300 V/µs. The device operates on dual supply voltages ranging from ±2.5 V to ±15 V, or single supplies from 5 V to 30 V. Key electrical parameters include an input offset voltage of 5 mV, input bias current of 3.5 µA, and input voltage noise density of 12 nV/√Hz. Each channel provides an output current capability of 140 mA with a common-mode rejection ratio of 75 dB. The component is housed in a 14-pin SOIC package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates four independent high-speed amplifiers within a single compact package for space-constrained designs.
• Delivers high slew rate performance suitable for driving fast-changing signals without distortion.
• Provides substantial output drive capability to interface directly with low-impedance loads.

Applications

• High-speed signal conditioning circuits
• Video buffering and distribution systems
• Precision data acquisition front-ends

Procurement Notes

Verify the specific suffix against official Renesas documentation, as the base model may have variations in packaging or temperature rating. Confirm RoHS compliance status through the manufacturer's latest datasheet. Check for end-of-life notifications or obsolescence warnings before finalizing procurement plans.

Selection Notes

Select this component when multiple high-speed channels are required in a limited footprint. Ensure the application benefits from the 140 mA output current and 300 V/µs slew rate. Verify that the 70 MHz bandwidth meets the system frequency requirements and that the 5 mV offset voltage is acceptable for the precision needs.

Part Context

This part belongs to the ISL55004 series of quad operational amplifiers designed for general-purpose high-speed applications. It represents a multi-channel solution derived from the single-channel ISL55004 architecture, allowing designers to utilize identical performance characteristics across four independent paths within one integrated circuit.

Replacement Considerations

Consult official substitution guides for verified equivalents. Cross-reference pinouts and electrical specifications carefully to ensure compatibility with existing board layouts and thermal constraints.
