Squarewave Oscillator Using TLC073
The new range of low-noise, highspeed and low-distortion BiMOS opamps from Texas Instruments, type TLC070 to TLC075, is intended for use in instrumentation, audio and automotive applications. This oscillator is an ideal example of its application: a stable, highly accurate squarewave at frequencies up to 60 kHz can be produced with an output current of ±30 mA.The TLC073, a dual op-amp with shutdown function, is used here. IC1a is configured as a standard squarewave generator, IC1b as a driver.
