MC3403PWG4

Instrumentation, Op Amps, Buffer Amps Overview

The MC3403PWG4 is a quad low-power operational amplifier manufactured by Texas Instruments. It features four independent amplifiers in a single package, designed for general-purpose applications requiring low power consumption. The device operates with a supply voltage range of 3 V to 36 V or dual supplies from ±1.5 V to ±18 V. Key electrical parameters include a gain-bandwidth product of 1 MHz, a slew rate of 600 mV/µs, and an input bias current of 500 nA. It provides a common-mode rejection ratio of 90 dB and can deliver up to 30 mA output current per channel. The component is housed in a 14-pin TSSOP package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Quad configuration integrates four low-power operational amplifiers into a single compact package.
• Rail-to-rail input capability allows operation with signals extending to the negative supply rail.
• Low power consumption design reduces overall system energy usage compared to standard bipolar op-amps.
• Wide single-supply operating range supports diverse voltage environments without complex biasing.

Instrumentation, Op Amps, Buffer Amps Applications

• Battery-powered instrumentation circuits
• General-purpose signal conditioning
• Active filter implementations
• Sensor interface stages

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'PWG4' confirms the TSSOP-14 package and lead-free RoHS compliance status as defined by Texas Instruments. Confirm the active lifecycle status directly with the manufacturer, as availability may vary. Ensure the ordering part number matches the exact pinout and thermal characteristics required for your PCB layout. Cross-reference the datasheet revision date to ensure compatibility with your design specifications.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a quad amplifier topology is required with moderate bandwidth and low quiescent current. It serves as a drop-in replacement for legacy quad op-amps where power efficiency is prioritized over high-speed performance. Consider the 1 MHz gain-bandwidth product for applications involving audio frequencies or slow-moving sensor signals. Evaluate the 30 mA output drive capability against load requirements to ensure sufficient current sourcing and sinking margins.

Instrumentation, Op Amps, Buffer Amps Part Context

The MC3403 series represents a family of quadruple low-power operational amplifiers. The PWG4 variant specifically denotes the plastic small-outline thin-shrink package (TSSOP) with green (RoHS compliant and no Sb/Br) compound. This packaging offers higher pin density than traditional DIP formats, facilitating automated surface-mount assembly. The device belongs to the broader category of general-purpose analog signal processing components used in consumer and industrial electronics.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Publicly confirmed substitute part numbers include LM324 variants and MC3303. Verify pin compatibility and electrical parameter overlaps before substitution. Ensure the alternative component meets the same voltage and temperature specifications.
