MAX41464GUB+

RF Transmitter Overview

The MAX41464 is a high-speed, precision current-sense amplifier featuring an integrated shunt resistor. It provides a differential input and single-ended output, designed for accurate measurement of voltage drops across the internal sense element. The device operates with a wide supply voltage range and offers low offset voltage and gain error to ensure high accuracy in power management applications.

RF Transmitter Feature Summary

• Integrated precision shunt resistor eliminates external component requirements
• High-speed operation suitable for demanding power conversion topologies
• Single-supply operation simplifies system design and integration

RF Transmitter Applications

• Point-of-load (POL) converters
• Battery management systems
• Industrial motor control circuits

RF Transmitter Procurement Notes

Verify the specific suffix GUB corresponds to the correct package type and temperature grade during procurement. Confirm that the + designation indicates lead-free status and RoHS compliance as per manufacturer standards. Ensure compatibility with existing board space constraints due to the integrated shunt configuration.

RF Transmitter Selection Notes

Select this component when board area is limited and external shunt resistors are undesirable. Consider the fixed gain characteristics inherent to the integrated design. Evaluate thermal performance requirements given the power dissipation of the internal shunt under maximum load conditions.

RF Transmitter Part Context

This part belongs to Maxim Integrated's family of current-sense amplifiers. It differs from discrete solutions by embedding the sense resistor directly within the IC package. This integration reduces parasitic inductance and improves overall system reliability compared to external shunt implementations.
