LMH6401IRMZR

Overview

The LMH6401IRMZR is a differential amplifier from Texas Instruments, classified as a variable gain amplifier (VGA) within the LMH6401 series. It features an ultra-wideband digital interface for gain control and operates with a slew rate of 17.4 kV/us. The device is housed in a UQFN-HR-16 package designed for surface mount installation. It supports a supply voltage range of 3.15 V to 5.25 V and consumes 55 mA of operating current. The component functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Ultra-wideband digital variable gain architecture
• Differential output configuration
• Integrated digital control interface

Applications

• High-speed data acquisition systems
• RF signal conditioning
• Test and measurement equipment

Procurement Notes

Verify the specific suffix 'Z' against official documentation to confirm tape-and-reel packaging specifications. Ensure the UQFN-HR-16 footprint matches the design layout. Confirm RoHS compliance status through the manufacturer's datasheet. Validate humidity sensitivity levels prior to storage and handling procedures.

Selection Notes

Select this component when a high-bandwidth differential VGA with digital gain adjustment is required. The 4.5 GHz bandwidth supports demanding RF applications. Consider the 55 mA current consumption and 3.15 V to 5.25 V supply requirements during power budgeting. The UQFN-HR-16 package offers a compact solution for space-constrained designs.

Part Context

This part belongs to the LMH6401 family of ultra-wideband amplifiers. It serves as a specialized variant optimized for digital gain control via a serial interface. The device integrates high-speed performance with flexible programmability, distinguishing it from fixed-gain or analog-controlled counterparts in the broader amplifier portfolio.
