Top Features

Packaging

  • Low-noise analog signal path
  • Device bandwidth is set via the FILTER pin
  • 5 µs output rise time in response to step input current
  • 80 kHz bandwidth
  • Total output error 1.5% typical at TA = 25°C
  • Small footprint, low-profile SOIC8 package
  • 1.2 mΩ internal conductor resistance
  • 2.1 kVRMS minimum isolation voltage from pins 1-4 to pins 5-8
  • 5.0 V, single supply operation
  • 133 to 185 mV/A output sensitivity
  • Output voltage proportional to DC currents
  • Factory-trimmed for accuracy
  • Extremely stable output offset voltage
  • Nearly zero magnetic hysteresis
  • Ratiometric output from supply voltage
  • Operating temperature range, –40°C to 150°C

The ACS715 is provided in a small, surface mount SOIC8 package (suffix LC). The leadframe is plated with 100% matte tin, which is compatible with standard lead (Pb) free printed circuit board assembly processes. Internally, the device is Pb-free, except for flip-chip high-temperature Pb-based solder balls, currently exempt from RoHS.
