The MAX40080 is a high-precision, fast-response, bi-directional current-sense amplifier with digital output and a very wide input common-mode range from -0.1V (ground sensing) to 36V.

The device features an ultra-low 5μV input offset voltage and a very low 0.2% gain error. The low input offset voltage is especially important because it allows using a small sense resistor, thus saving power dissipation, but at the same time not compromising the measurement accuracy. The device also features a programmable input sensing range between ±10mV and ±50mV (or programmable input gain between 125V/V and 25V/V) which is very useful to enhance accuracy at low current.

The device includes an analog-to-digital converter with a programmable sample rate and 12-bit resolution (13-bit including sign bit for current measurement) and features an I2C compliant and SMBus compatible interface.

The device features a wake-up current threshold and auto-shutdown mode when the I2C is inactive. Both these features are designed to minimize power consumption.

The device is available in a small 12-pin WLP (and also a 12-pin TDFN) and is specified over the -40°C to +125°C extended operating temperature range.

Features and Benefits

  • Easy-to-Reach Test Points
  • Fully Assembled and Tested
  • Windows 7, 8, and 10-Compatible Software

Product Detail

The MAX40080 evaluation system (EV system) provides a single platform to evaluate the MAX40080 precision digital current-sense amplifier. The EV system consists of two boards connected through headers, a MAX32666FTHR microcontroller board, and the MAX40080 EV kit board. The MAX32666FTHR contains the firmware necessary to use the PC GUI program and provides power to the MAX40080 EV kit board. The MAX40080 EV kit board ships with jumpers preinstalled for quick evaluation of the MAX40080.
