MC33072D

Instrumentation, Op Amps, Buffer Amps Overview

The MC33072D is a dual-channel monolithic operational amplifier from onsemi, housed in an 8-pin SOIC package. It features a 4.5 MHz gain bandwidth product and a 13 V/µs slew rate. The device supports wide single supply operation from 3.0 V to 44 V, with an input common mode voltage range that includes ground potential (VEE). Key electrical characteristics include a maximum input offset voltage of 5.0 mV, typical input bias current of 100 nA, and output short circuit protection. It operates within a temperature range of -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Utilizes a Darlington input stage for high input resistance and low input offset voltage without JFET technology.
• Features an all NPN output stage providing large output voltage swing and high capacitance drive capability.
• Includes output short circuit protection and ESD diodes/clamps for input protection.

Instrumentation, Op Amps, Buffer Amps Applications

• Fast settling D-to-A current to voltage conversion
• High speed low voltage comparator circuits
• Active high-Q notch filters
• Low voltage fast D/A converters

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'D' corresponds to the standard performance grade and SOIC-8 package as documented in the MC34071/D datasheet. Confirm the operating temperature range aligns with industrial requirements (-40°C to +85°C). Ensure supply voltage constraints between 3.0 V and 44 V are respected in the design. Check for RoHS compliance status if environmental regulations apply.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a general-purpose dual op amp with bipolar input characteristics is required. It is suitable for applications needing rail-to-rail-like output swing relative to the negative rail and ground-referenced inputs. Consider the 5.0 mV max input offset voltage for precision needs. The SOIC-8 package is appropriate for surface mount assembly where space is limited compared to DIP packages.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MC33071/72/74 series of monolithic operational amplifiers manufactured by onsemi. The series shares core architecture including the Darlington input and all-NPN output stages. Other variants include single (MC33071) and quad (MC33074) channel versions, as well as automotive qualified NCV prefixes. The 'D' suffix specifically denotes the SOIC surface-mount package configuration.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct functional substitutes within the same family include MC33072DG (DIP package) or MC33072ADR2G (if higher precision A-grade is acceptable). Cross-family replacements like MC34072 share identical electrical specifications but may differ in temperature ranges or packaging options.
