Hello,
I ultimately would like to take a 1Vp-p sine wave and amplify the voltage and current so that there is 4-5Vp-p and 500mA at the output to drive a 7ohm device. I have a +5V power supply from a USB port that can source 500mA.
I have implemented a 741 with a 2.5V DC bias to essentially create a 50% duty cycle PWM to drive a BJT to supply the current amplification, but I am curious if there is any other way to amplify the voltage and current with a 1Vp-p sine wave and a single +5V power supply???? Any suggestions and/or tips are welcomed.
Thank you.
