Introduction

AI Translation

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.

Features

AI Translation
  • 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
