LTC6104CMS8#TRPBF

Instrumentation, Op Amps, Buffer Amps Overview

The LTC6104CMS8#TRPBF is a high voltage, high side, bi-directional current sense amplifier manufactured by Analog Devices Inc. It operates on supply voltages from 4V to 60V with a maximum absolute rating of 70V. The device features a maximum input offset voltage of ±450µV and a typical supply current of 520µA at 12V. It provides a fast response time of 1µs and supports a maximum output current of ±1mA. Gain is configurable via external resistors, allowing separate configuration for both current directions. The component is specified for operation within a temperature range of –40°C to 85°C and is housed in an 8-lead MSOP package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Bi-directional current sensing capability translating shunt voltage into a ground-referenced signal
• Configurable gain using external resistors with independent settings for each direction
• Low DC offset voltage enabling the use of small shunt resistors to minimize power loss
• High power supply rejection ratio ensuring accuracy under varying supply conditions

Instrumentation, Op Amps, Buffer Amps Applications

• Current shunt measurement
• Battery monitoring systems
• Remote sensing applications
• Power management circuits

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify that the specific suffix #TRPBF corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the 'C' grade designation aligns with the intended operating temperature range of –40°C to 85°C for your specific application environment. Ensure compatibility with the 8-lead MSOP footprint during PCB layout verification.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high-side bi-directional current monitoring is required within a 4V to 60V supply range. The low offset voltage makes it suitable for applications demanding high accuracy with minimal shunt resistor values. Consider the thermal dissipation limits if operating near the maximum supply voltage with high output currents. Verify that the external resistor selection allows for the desired gain and output voltage swing within the specified constraints.
