RC4558IPW

Instrumentation, Op Amps, Buffer Amps Overview

The RC4558IPW is a dual general-purpose operational amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 3 MHz and a slew rate of 1.7 V/µs. The device operates within a supply voltage range of 10 V to 30 V or ±5 V to ±15 V. Key electrical parameters include an input offset voltage of 6 mV, input bias current of 500 nA, and input voltage noise density of 8 nV/√Hz. It provides a common-mode rejection ratio of 90 dB and supports up to 10 mA output current per channel. The component is housed in an 8-TSSOP package and functions within a temperature range of -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix IPW confirms the industrial temperature grade (-40°C to +85°C) and TSSOP-8 surface-mount packaging. Confirm RoHS compliance status with the manufacturer datasheet before integration. Ensure the ordering part number matches the required lead time and availability constraints for production schedules.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a dual-channel op amp with moderate bandwidth and low noise is required for industrial environments. It serves as a direct replacement for μA741-based designs lacking offset nulling capabilities. Consider the TSSOP-8 footprint for space-constrained surface-mount applications requiring through-hole performance characteristics.

Instrumentation, Op Amps, Buffer Amps Part Context

The RC4558 series comprises dual operational amplifiers electrically similar to the classic μA741 but without offset null pins. The RC4558IPW specifically denotes the industrial temperature variant packaged in a thin-shrink small-outline (TSSOP) format. This family is widely utilized in audio processing and instrumentation where reliable general-purpose amplification is necessary.
