Product Overview

MAX40080 is a high-precision, fast-response, bi-directional current sense amplifier with digital output and very wide input common-mode range from -0.1V (ground sensing) to 36V. It features an ultra-low 5µV input offset voltage and very low 0.2% gain error. Low input offset voltage is especially important because it allows using a small sense resistor, thus saving power dissipation, but at same time not compromising the measurement accuracy. It 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. Device includes an analogue-to-digital converter with a programmable sample rate and 12bit resolution (13bit including sign bit for current measurement) and features I2C compliant and SMBus compatible interface. It features a wake-up current threshold and auto-shutdown mode when I2C is inactive. Both these features are designed to minimize power consumption.
  • Programmable sample rate up to 1Msps
  • Programmable input sense range (±10mV and ±50mV)
  • Very low 5µV input offset voltage allows using a small sense resistor
  • I2C compliant and SMBus compatible interface with smart modes to save power
  • Bi-directional current sensing
  • Common mode voltage monitoring up to 36V
  • Peak current log, 64-cell deep FIFO
  • Programmable overcurrent/voltage thresholds and undervoltage threshold
  • Alert output with programmable response time
  • Available in a small 12-pin WLP, -40°C to +125°C extended operating temperature range
