    6 x TLC272 Circuits

    Browse through a total of 6 TLC272 Circuits.

    TLC272 Peak Indicator Circuit This peak indicator circuit signals thru 2 led’s the exceeding of a pre-estabilished value of any stereo audio channel. Signals from the 2 channels are rectified (monoalternance) with D1 and D2 and the resulted voltage is applied on OA IC TLC272 inversor entries. The peak indicator circuit can be used up to 20kHz...
    Audio Equipment Autodisconnecting Circuit This simple circuit disconnects equipment rack of your audio in case has not delivered a sound a specified period. Circuit is operated by pressing his S1, which produces loading of C1. Further, switch IC1b AO exit in the state “up” and the audio equipment is powered from the network through semiconductor relay...
    Squelch Circuit Squelch is a circuit that acts to suppress the audio (or video) output of a receiver in the absence of a sufficiently strong desired input signal. This squelch circuit is simple and has an amplification for sufficiently large to be incorporated into an assembly of automatically control from a wide range of radio receivers. The...
    Capacitor Meter Circuit The capacitor meter presented here can measure capacities between 100pF and 1uF on five areas of measurement, more we can say multimeter or tester. Circuit consists of an oscillator with variable frequency, a divided frequency and measurement stage. The Oscillator is based on a inversor from a 74HC14 and generates a frequency...
    Infrared Detector Circuit with PID20 This infrared detector circuit uses a passive IR-detector component PID20. It converts heat radiation into electrical impulses. The output voltage of the PID20 increases when an object comes close to it, this object must be warmer than the surroundings. The voltage changes at the output of the IR sensor are sensed by the...
    TLC272 Datasheet The TLC272 and TLC277 precision dual operational amplifiers combine a wide range of input offset voltage grades with low offset voltage drift, high input impedance, low noise, and speeds approaching those of general-purpose BiFET devices. The extremely high input impedance, low bias currents, and high slew rates make these...
