Chip K157HP1

K157KhP1 microcircuits are a two-channel threshold circuit, each channel of which includes a preamplifier with an amplitude discriminator at the input and an indicator amplifier, which includes a time interval shaper and a power amplifier.
These channels have in common a mode device that sets the reference and bias voltages for both amplifiers, and a rectifier of the automatic recording level control system that processes the sum of the signals of the two channels.
Designed to control devices for indicating peak signal levels (LEDs, incandescent lamps) in the recording channel and to generate control signals for the automatic recording level control system.
Contains 89 integral elements.
