Description
LINEAR INTEGRATED CIRCUIT
TRIAC/SCR PHASE CONTROL
The L 120A is a monolithic integrated circuit in 16-lead dual in-line plastic package. It incorporates the following functions:
AC supply 50/60 Hz Zero-voltage and zero-current detector Ramp generator Inhibition of casual firing pulses Stabilization of the internal positive DC supply High gain operational amplifier Output short-circuit protection
The L 120A is intended for use as a phase controller in industrial and consumer applications.
