LM613IWMX

Overview

The LM613IWMX is a monolithic integrated circuit from the Super-Block family, housed in a 16-pin Wide SOIC (WM) package. It integrates dual operational amplifiers, dual comparators, and an adjustable voltage reference. The op-amps feature a supply voltage range of 4V to 36V, low operating current of 300 μA, and wide common-mode input range extending from V− to (V+ − 1.8V). The internal band-gap reference provides a nominal 1.24V output with ±0.6% initial tolerance and can be programmed via external resistors to voltages between 1.2V and 6.3V. The device supports military temperature operation (-55°C to +125°C) and offers high integration for transducer and data acquisition systems.

Feature Summary

• Integrates dual high-speed operational amplifiers, dual comparators, and a programmable voltage reference within a single 16-pin package.
• Operational amplifiers provide wide differential input voltage capability up to ±36V and wide common-mode range without requiring phase inversion.
• Voltage reference utilizes a stable band-gap design tolerant of large capacitive loads, featuring low dynamic output impedance and tight initial tolerance.
• Designed for single-supply applications, offering low power consumption and wide output swing suitable for bridge driving and signal conditioning.

Applications

• Transducer bridge driver
• Process and mass flow control systems
• Power supply voltage monitor
• Buffered voltage references for A/D converters

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'IWMX' corresponds to the industrial grade wide SOIC package variant. Check for RoHS compliance status as indicated in distributor listings, noting potential discrepancies with original datasheet specifications. Ensure storage conditions adhere to moisture sensitivity level ratings prior to soldering.

Selection Notes

Select this component when board space reduction is critical due to its multi-function integration. It is suitable for designs requiring a stable, programmable reference alongside signal processing capabilities. Consider the wide supply voltage range and input characteristics for single-supply environments. Evaluate thermal performance requirements against the specified junction-to-ambient resistance for the surface-mount package.
