1_kHz_SQUARE_TRIANGLE

National LM386 opamp operating from 9-V supply generates 1-kHz square wave at 0.5 W for driving 8-ohm loudspeaker or other load. Exact frequency is determined by values used for R1 and C1. Triangle outputcan betaken from pin 2. Pins 1 and 8 can be shorted because DC offset voltages are unimportant.- Audio Handbook, National Semiconductor, Santa Clara, CA, 1977, p 4-30-4-33.
