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.
