MC33174VDG

Instrumentation, Op Amps, Buffer Amps Overview

The MC33174VDG is a quad bipolar operational amplifier from onsemi, operating within a supply voltage range of 3.0 V to 44 V or ±1.5 V to ±22 V. It features a gain bandwidth product of 1.8 MHz and a slew rate of 2.1 V/µs. The device draws 180 µA per amplifier with an input common mode range extending to the negative rail (VEE). Key electrical characteristics include a maximum input offset voltage of 6.5 mV, input bias current up to 200 nA, and output short circuit protection. It is housed in a 14-pin SOIC package and supports an extended industrial temperature range.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'VD' indicates the extended temperature range (-40°C to +125°C) compared to standard variants. Confirm the package type matches the required PCB footprint. Check for RoHS compliance status as per the latest datasheet revision. Ensure availability aligns with automotive quality requirements if applicable.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a quad amplifier configuration is needed with low power consumption under 200 µA per channel. It is suitable for applications requiring wide supply voltage ranges up to 44 V. Consider the extended temperature rating for harsh environments. Compare against JFET-input op-amps if lower input bias current is critical, noting the trade-off in input capacitance.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MC3317x series of monolithic operational amplifiers manufactured by onsemi. The series includes single, dual, and quad configurations sharing similar electrical characteristics. The 'MC33174' designation specifically refers to the quad version, while the 'VD' suffix denotes the extended temperature variant in a surface-mount package.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct pin-compatible replacements within the same family include MC33174DG for industrial temperature range. Verify that substitute components maintain the 1.8 MHz gain bandwidth and 2.1 V/µs slew rate. Ensure the replacement package matches the 14-SOIC form factor.
