Overview

Current sense amplifiers, also called current shunt monitors, are specialized differential amplifiers with a precisely matched resistive gain network. Designed to monitor the current flow by measuring the voltage drop across a sense element, typically a shunt resistor. Tend to be easier to use, more precise and less prone to noise. Support currents from 10s of μA to 100s of A. Natively support common - mode voltages from -16 to +80 V and with additional circuitry up to 100s of volts.

Key features

Designed to monitor the current flow by measuring the voltage drop across a sense element, typically a shunt resistor
Tend to be easier to use, more precise and less prone to noise
Support currents from 10s of μA to 100s of A
Natively support common - mode voltages from -16 to +80 V and with additional circuitry up to 100s of volts
Real - time overcurrent protection
Current and power monitoring for system optimization
Current measurement for closed - loop feedback
Integrates the amplifier along with all the gain - setting resistors which enables small and unified temperature drift
Integrates the full analog signal processing and provides a voltage or current output
Integrates the full signal conditioning path and utilizes a standard 2 - wire digital interface
Provides a simple ALERT signal when the load current exceeds a threshold
Offers a low - drift, precision integrated sense element
Able to detect load short to ground
Current is monitored directly from the source
High immunity to ground disturbance
Integrated gain resistors provide excellent matching to enable a higher performing and more stable platform
Reduction in board space requirements
High dynamic changes in the common - mode voltage are difficult to achieve with standard op amps
Unique input architecture allows for the common - mode voltage to greatly exceed the device supply voltage
Simple to implement and low - cost solution
Wide range of available options
True differential measurement across the shunt resistor
Lower VOFFSET saves system power by enabling the use of smaller value shunt resistors to achieve the same error level
