LM392DGKR

Overview

The LM392DGKR is a dual low-power operational amplifier and voltage comparator manufactured by Texas Instruments. It features a wide single-supply voltage range of 3 V to 32 V and a low output saturation voltage of 250 mV at 4 mA. The device offers a bandwidth of 1 MHz, a conversion rate of 100 mV/µs, and an input offset voltage of 7 mV. It operates within a temperature range of 0°C to 70°C and is housed in an 8-VSSOP package.

Feature Summary

• Combines dual operational amplifiers and voltage comparators in a single low-power package
• Provides excellent speed-to-power performance with 40 ns propagation delay
• Qualified for automotive applications ensuring reliability in demanding environments

Applications

• Transducer amplifier circuits
• Automotive electronic systems requiring qualified components
• Low-power signal conditioning applications

Procurement Notes

Verify the specific suffix DGKR corresponds to the 8-VSSOP surface-mount package when sourcing. Confirm automotive qualification status if required for your design. Ensure the supply voltage does not exceed the maximum rating of 32 V. Check RoHS compliance documentation for environmental regulations. Validate the operating temperature range against your system's thermal requirements.

Selection Notes

Select this component when a combined op-amp and comparator solution is needed in a compact surface-mount format. It is suitable for designs prioritizing low power consumption alongside moderate speed. Consider the 8-VSSOP footprint for PCB layout constraints. Evaluate the 1 MHz bandwidth against signal frequency requirements. Verify compatibility with single-supply operation up to 32 V.

Part Context

This part belongs to the LM392 family of low-power operational amplifiers and voltage comparators. It serves as a versatile analog signal processing component. The DGKR variant specifically denotes the VSSOP surface-mount packaging option. It complements other devices like the LM393 comparator series. The component is designed for general-purpose analog applications.

Replacement Considerations

The LM392DR is a pin-compatible alternative in SOIC-8 packaging. Both share similar electrical characteristics and functionality. Verify package dimensions and thermal properties when substituting. Ensure the replacement meets the same automotive qualification standards if applicable.
