-40°C to +125°C Operating Temperature Range

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. The MAX40016 (WLP package) drops a typical of 60mV at 3A from the voltage input to load output .

The MAX40016's integrated current-sensing element saves the space and cost of an external high-power, precision current sense resistor. The MAX40016 is offered in an ultra-tiny, 1.98mm x 1.31mm, 15-bump waferlevel package (WLP), further reducing board space. The MAX40016 is also available in a 4mm x 4mm 16-pin TQFN package.

The MAX40016 operates with a supply voltage from 2.5V to 5.5V. The device features a low-power mode in which the current-sensing element remains on, but the outputs are turned off to reduce the total supply current below 10µA (max).

The MAX40016 also includes a committed on-board amplifier with an internal gain of 1.5V/V. The MAX40016 operates over the -40°C to +125°C temperature range.

Product Details

The MAX40016 evaluation kit (EV Kit) provides a proven design to evaluate the MAX40016 wide dynamic range current sense amplifier. The MAX40016 integrates the sense element, eliminating a bulky and costly external sense/ shunt resistor. The device measures four of decades of current (from < 300µA to 3A) while maintaining a highly accurate output reading. This EV kit demonstrates the MAX40016 in a tiny, space-saving, 15-bump wafer-level package (WLP).

The MAX40016 EV kit PCB comes with the MAX40016ANL+ device installed.
