LMH6401IRMZT

Overview

The LMH6401IRMZT is a single-channel differential variable gain amplifier (VGA) from Texas Instruments, designed for ultra-wideband applications up to 5 GHz. It features a gain bandwidth product of 4.5 GHz and a slew rate of 18.2 kV/µs. The device operates on a supply voltage ranging from 4 V to 5.25 V with a typical operating current of 69 mA. Key electrical specifications include a common-mode rejection ratio (CMRR) of 38.4 dB, an input bias current of 100 µA, and an input offset voltage of 10 mV. It utilizes a UQFN-HR-16 surface-mount package and functions within a temperature range of -40°C to +85°C.

Feature Summary

Digital control interface for precise gain adjustment
Differential input and output architecture for signal integrity
Ultra-wideband frequency response suitable for high-speed data transmission

Applications

Wireless infrastructure base stations
Test and measurement equipment requiring wideband amplification
High-speed digital communication links

Procurement Notes

Verify the specific suffix 'ZT' against the manufacturer's latest datasheet to confirm reel packaging and moisture sensitivity level requirements. Ensure compatibility with the UQFN-HR-16 footprint during PCB layout. Confirm that the design accounts for the specified 69 mA operating current and thermal dissipation limits within the -40°C to +85°C operational range.

Selection Notes

Select this component when a differential VGA with digital gain control is required for frequencies approaching 5 GHz. Compare the 4.5 GHz gain-bandwidth product and 18.2 kV/µs slew rate against system bandwidth needs. Evaluate the 100 µA input bias current and 10 mV offset voltage against signal chain accuracy requirements. Consider the UQFN-HR-16 package size for space-constrained designs.

Part Context

The LMH6401 belongs to the LMH6401 series of ultra-wideband amplifiers by Texas Instruments. It is categorized as a differential amplifier and specifically functions as a variable gain amplifier.
