Category: Inside Circuits Views: 1081 Rank: 0 The circuit uses the LM301 has an input leakage of only 2 pA typical at 75 ° C and is used with 1 M ohm input resistance.  The operating voltage has to be +-12V.
Related circuits Using inexpensive components, you can fit a simple probe circuit into a pencil-sized enclosure. When both LEDs are on, the probe indicates the presence of an ac voltage; either LED alone indicates the presence and polarity of a de voltage. The diode-bridge arrangement allows one-way current... A JFET (MPF102) is used to chop a dc signal for amplification in an ac coupled amplifier. Q3 is the chopper element and Q1-Q2 forms the multivibrator to derive a chopping signal. Simple Wwv Converter For Auto Radios Circuit This simple frequency converter mixes the 15-MHz WWV/WVH signal with a 16-MHz signal from the LO to convert it down to 1 MHz so that it can be heard Analog-multiplexer-with-buffered-input-and-output · This circuit is used for analog signal selection or time division multiplexing. As shown, the feedback signal places the selected amplifier channel in a voltage follower (noninverting unity gain) configuration, and provides very high input impedance and low output impedance. The single... This circuit produces a pure, - 80-dB THD sine wave with a frequency that is equal to the fc of IC3"s filter. A TT The swept-frequency oscillator offers an inexpensive source of discrete frequencies for use in testing digital circuits. In this configuration, the circuit generates an 80-second seguence of eight frequencies, dwelling for 10 seconds on each frequency. You can change the dwell time or the... Backup Supply Activates By Drop-In Main Supply A supply monitor using two TL7702A chips monitors the ± 15-V supplies and activates the back This application uses the timer connected for astable (free-running) operation, with a modulating signal again applied to the control voltage terminal.
