LM613IWM

Overview

The LM613IWM is a monolithic integrated circuit containing dual operational amplifiers, dual comparators, and an adjustable voltage reference within a 16-pin Wide SOIC (WM) package. It operates on a supply voltage range of 4V to 36V with a typical operating current of 300 μA per op-amp. The internal band-gap reference provides a nominal output of 1.244V with ±0.6% initial tolerance and can be programmed from 1.2V to 6.3V using external resistors. The device features wide common-mode input ranges extending to the negative rail and supports large differential input voltages up to ±36V.

Feature Summary

• Integrates dual high-speed operational amplifiers, dual comparators, and a programmable band-gap voltage reference in a single space-saving package.
• Operational amplifiers provide wide supply voltage operation and low power consumption suitable for transducer and data acquisition systems.
• Voltage reference maintains stability under large capacitive loads and allows output voltage programming via two external resistors.

Applications

• Transducer bridge drivers
• Process and mass flow control systems
• Power supply voltage monitors
• Buffered voltage references for analog-to-digital converters

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'IWM' corresponds to the industrial temperature grade and 16-Wide SOIC package variant. Review the official datasheet for absolute maximum ratings and thermal resistance values to ensure proper board layout and heat dissipation strategies are implemented before integration.

Selection Notes

Select this component when a combined solution for signal conditioning, comparison, and stable reference generation is required to minimize board space. Ensure the application utilizes single-supply configurations compatible with the 4V to 36V operating range. Consider the wide common-mode input capability if interfacing with sensors generating large common-mode signals relative to ground.

Part Context

The LM613 belongs to the Super-Block family, designed as a monolithic alternative to multi-chip solutions. Originally developed by National Semiconductor, the product line was transferred to Texas Instruments following corporate acquisitions. This integration reduces system complexity and cost while maintaining performance levels comparable to discrete component implementations in measurement applications.
