Chapter 20 – Power gain stages for monolithic amplifiers

Most monolithic amplifiers cannot supply more than a few hundred milliwatts of output power. Standard IC processing techniques set device supply levels at 36V, limiting available output swing. Additionally, supplying currents beyond tens of milliamperes requires large output transistors and causes undesirable IC power dissipation.
