The MAX40016 is a very wide range current sense amplifier (CSA) with internal sense element that senses from less than 300µA to greater than 3A current range. The 4-decade sensed current functions with 1% (typical) gain error and offers three, multiplexed programmable output ranges in order to interface with 12-bit ADCs. Having an integrated sense element has the extra advantage that the entire current measuring path can be factory-trimmed, saving the user from having to calibrate independent sense resistors and CSAs.

• Integrated current sense element saves the space and cost of expensive precision sense resistors.
• 4-decade measurement range. Maintains accuracy from <, 300µA to >, 3A
• Withstands overloads to 4A
• Three multiplexed scaling resistor outputs allow full dynamic range while interfaced to 12-bit ADCs
• Low power mode reduces supply current to 10µA max
