5-watt AF power amplifier with 16-ohm load connected to ground using no bootstrap. The ECG1116 is a 12-pin QIP. To obtain the rated output heatsinking is required. Capacitor C3 is typically 330 pF, while C7 is 1500 pF. Generally C7 is five times greater than C3. Supply voltage ripple rejection is improved by connecting a capacitor (10 to 100 μF at 25 volts) between pin 7 and ground. Frequency response is from 40 hertz to 20 kilohertz (courtesy GTE Sylvania Incorporated).
