APX4558IS-13

Overview

The APX4558IS-13 is a dual-channel low-noise operational amplifier manufactured by Diodes Incorporated. It features a gain-bandwidth product of 3 MHz and a slew rate of 1.1 V/us. The device operates within a supply voltage range of 5 V to 15 V, consuming 1.25 mA of quiescent current per channel. Key electrical specifications include an input offset voltage of 500 uV, input bias current of 150 nA, and input voltage noise density of 8 nV/sqrt Hz. It provides rail-to-rail output capability with a maximum output current of 30 mA per channel and a common-mode rejection ratio of 90 dB.

Feature Summary

• Dual-channel architecture designed for low-noise audio applications
• Rail-to-rail output swing capability
• Low input voltage noise density for high-fidelity signal processing

Applications

• Audio preamplifiers
• Set-top boxes

Procurement Notes

Verify component authenticity through authorized Diodes Incorporated channels or certified distributors. Confirm the specific suffix IS-13 matches design requirements. Check for end-of-life status as discontinuance notifications may apply. Ensure RoHS compliance documentation aligns with regulatory needs. Validate package integrity upon receipt.

Selection Notes

Select this component when low noise performance is critical in dual-channel designs. Compare against standard general-purpose amplifiers if higher bandwidth is required. Consider the 3 MHz gain-bandwidth product for audio frequency ranges. Evaluate power consumption constraints against the 1.25 mA operating current. Verify supply voltage compatibility within the 5 V to 15 V range.
