LM614 MDC

Instrumentation, Op Amps, Buffer Amps Overview

The LM614 is a monolithic Super-Block device integrating four operational amplifiers and an adjustable voltage reference in a single 16-pin package. It features a wide supply voltage range of 4V to 36V, low operating current of 450μA, and a wide common-mode input range from V− to (V+ − 1.8V). The integrated band-gap reference provides an initial tolerance of ±2.0% and allows output programming between 1.2V and 5.0V via external resistors.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Integrates four high-speed operational amplifiers with a stable band-gap voltage reference on a single die
• Features lateral PNP inputs tolerant of large differential and common-mode voltages up to the absolute maximum supply limit
• Offers flexible output stages capable of driving significant capacitive loads without oscillation

Instrumentation, Op Amps, Buffer Amps Applications

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

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix MDC indicates the DIESALE configuration when sourcing. Confirm that the selected variant meets the required industrial temperature range specifications. Ensure proper handling procedures are followed due to limited built-in ESD protection on the MOS gates during storage or handling.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring high integration to reduce board space and cost. It is suitable for transducer and data acquisition systems where large common-mode signals are present. Consider the wide supply voltage range and low quiescent current requirements when designing single-supply circuits.

Instrumentation, Op Amps, Buffer Amps Part Context

The LM614 belongs to Texas Instruments' Super-Block family, designed as a space-saving monolithic alternative to multichip solutions. It combines a stable voltage reference with four wide-output-swing op-amps, offering high integration levels without sacrificing performance in transducer and measurement systems.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The LM124 series serves as a related predecessor within the same product lineage. While sharing similar functional architectures, the LM614 offers improved slew rates and lower crossover distortion compared to older designs.
