About this item

  • The OPA548 device is a low-cost, high-voltage and high-current operational amplifier that's ideal for driving a wide variety of loads.
  • The OPA548 device is internally protected against over-temperature conditions and current overloads. In addition, the OPA548 device was designed to provide an accurate, user-selected current limit. Unlike other designs, which use a power resistor in series with the output current path, the OPA548 device senses the load indirectly.
  • Supply Voltage Range: ±10V~±30V；Module Gain: Default 33x
  • Continuous 3A output current
  • Can drive various loads like motor / speaker / transformer / audio amplifier , Can amplify triangular / sine / square wave signal
