APEX SA50
The SA50 is a pulse width modulation amplifier that can supply 5A continuous current to the load. The full bridge amplifier can be operated over a wide range of supply voltages. The PWM circuitry is internal as well, leaving the user to only provide an analog signal for the motor speed/direction, or audio signal for switchmode audio amplification.| Part No. | SA50 |
