LMH6601MGX/NOPB

Overview

The LMH6601MGX/NOPB is a single-channel, high-speed CMOS operational amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 250 MHz and operates on a supply voltage range of 2.4V to 6V. The device incorporates a shutdown function for power management and delivers rail-to-rail input and output capabilities. Key electrical specifications include an input bias current of 50 pA, an input offset voltage of 2.4 mV, and a quiescent current of 9.6 mA per channel. It provides an output drive capability of 180 mA and is housed in a compact SC-70-6 surface-mount package.

Feature Summary

• Integrates a dedicated shutdown pin to minimize power consumption when the device is not in active use.
• Supports rail-to-rail signal swing at both the input and output terminals to maximize dynamic range.
• Utilizes CMOS technology to achieve low input bias current while maintaining high-speed performance.

Applications

• Portable battery-powered instrumentation requiring low quiescent current
• Video buffering and signal conditioning circuits
• Active filtering in communication systems

Procurement Notes

Verify the component authenticity by checking the manufacturer's marking code against official datasheet references. Confirm that the ordering suffix matches the specified SC-70-6 package and temperature range. Ensure compliance with RoHS directives as indicated by the NOPB designation. Cross-reference the part number with authorized distributors to validate supply chain integrity before procurement.

Selection Notes

Select this component for designs requiring a balance between high bandwidth and low power consumption in small form factors. The rail-to-rail operation makes it suitable for single-supply applications where signal swing is critical. Consider the 180 mA output drive when interfacing with low-impedance loads. Evaluate the 250 MHz bandwidth against system requirements to ensure adequate phase margin and stability in feedback configurations.

Part Context

This device belongs to the LMH6601 series of high-speed operational amplifiers from Texas Instruments. The series is characterized by its CMOS architecture, which enables low power operation compared to bipolar counterparts. The LMH6601MGX/NOPB variant specifically denotes the reel-packaged version in the SC-70-6 footprint, designed for automated surface-mount assembly processes in consumer and industrial electronics.

Replacement Considerations

Direct replacements within the same family include LMH6601MG/NOPB (tube packaging) or LMH6601MFX/NOPB if pin compatibility allows. Verify functional equivalence regarding shutdown logic and electrical parameters before substitution.
