Analog Devices / Maxim Integrated MAX40016 4-Decade Current Sense Amplifier

Analog Devices Inc. MAX40016 4-Decade Current Sense Amplifier features an internal sense element that senses current range from less than 300µA to greater than 3A. The 4-decade sensed current functions with a 1% (typical) gain error. The amplifier offers three multiplexed programmable output ranges to interface with 12-bit ADCs. Having an integrated sense element means the entire current measuring path can be factory-trimmed. This feature saves time and cost by not having to calibrate independent sense resistors and CSAs. The Analog Devices Inc. MAX40016 4-Decade Current Sense Amplifier drops a typical of 60mV at 3A from the voltage input to load output.

Features

  • Integrated current sense element saves the space and cost of expensive precision sense resistors
  • 4-decade measurement range
    • Maintains accuracy from < 300µA to > 3A
  • The low voltage drop across sense element
    • 60mV (active mode, 3A load)
    • 35mV (low power mode, 3A load)
  • Withstands overloads to 4A
  • Three multiplexed scaling resistor outputs allow full dynamic range while interfaced to 12-bit ADCs
  • +2.5V to +5.5V input supply voltage range
