Abstract

PURPOSE: To make easy for solidstate circuit constitution and circuit integration, by improving the temperature characteristics, through the setting of the ON-OFF level with current control, in stereo indicator driving circuits.
CONSTITUTION: The input current Iin from the input power supply 11 is outputted from the terminal OUT via the current amplifier 12 and transistor Q2. In this case, the constant currents I1 and I2 are respectively fed to the input and output terminal of the amplifier 12 from the constant current sources 11 and 13 consisting of transistor Q1, Further, a positive feedback loop consisting of the transistors Q1, Q2 and amplifier 12 is constituted. The transistor Q2 controls the transistor Q1 according to the resulting current 15 of the output current I4 of the amplifier 12 and the constant current I2 and feeds signal On and OFF with the hysteresis characteristics with a given level of the input current Iin to the terminal OUT.
