9 Volt Power Supply Circuit Diagram Using IC 7809

Description

Circuit showing a 9 volt power supply . Here we have used a bridge rectifier and 7809 ic for making this circuit.Where the ic regulate the output to 9 v,1 A .This voltage every time constant.Are you interested ?

Circuit diagram with Parts list.

Notes.

If a current of 300 mA or above is required, fit a proper heat sink to the IC 7809.
If 1A bridge is not available, make one using four 1N 4007 diodes.

High impedance DC Voltmeter by IC CA313048

The MOSFET input of the CA3140 makes it ideally suited for use in a high impedance DC voltmeter. Switch S1 is the range selector. The input impedance is limited to 10M by the resistors used in the voltage divider, but this is still a very acceptable value. Before switching on for the first time, the mechanical zero adjustment of the 100m A instrument should be set so that the pointer rests just below zero on the scale. The unit is then switched on and with the input shorted, TR1 is adjusted until an exact zero indication is obtained. The TR2 is used for calibrating the meter so that the full scale deflection in the three ranges is 1V, 10V and 100V. The supply voltage can be anything between 8 and 20V. The current consumption is less than 6mA at 12V. The accuracy of this voltmeter depends mainly on the quality of the 100m A instrument and the care with which the unit has been calibrated.

Part List

R1=8.2Mohms	R7=1Kohms	C2-3=10uF 25V
R2-3=820Kohms	R9-10=10Kohms	D1=1N4148
R4=82Kohms	TR1=10Kohms trimmer	IC1= CA3130
R5=100Kohms	TR2=25Kohms trimmer	VV1=100uA instrument
R6-8=47Kohms	C1=1.5uF 25V

Mini Audio Amplifier Circuit using IC KA2209

This is 2X1W audio amplifier circuit with mini-KA2209 IC. It may work well from 3-12V DC and will work from a battery since the quiescent current drain is low. It requires no heat sink for normal use. Input and output are both ground referenced. Maximum output is obtained with a 12V power supply and 8 ohm speaker, however, is especially suitable for driving headphones from a supply as low as 3V.

Amp mini circuit only a few external components, the IC contains most of the necessary circuits. R1, R2 and R3, R4 are the resistances of feedback. C1 provides power supply decoupling. C2 and C3 are the input coupling capacitors, which block any DC that might be present on the inputs. C4, C5 DC block in the feedback loop of the inverting input and C6, C7 are the output coupling capacitors. C8, C9 and R5, R6 act as a Zobel network to provide a high frequency load for stability in the frequencies where the inductive reactance of the loudspeaker can be strong too. The boat provides the attenuation of input level.

One IC Transmitter Wiring diagram Schematic

Free Circuit Diagrams 4U has given you many transmitter schema diagrams today Im going to give you some transmitter schema with some modifications.This schema can send signals up to 100 M.Here we have used IC UPC 1651.This schema can be operated with 6V.The special thing of this schema is we can build this schema with one IC.

Note :

# Build this schema with 6V power supply

IC 555 Tester Circuits

555 timer tester is a simple circuit that serves to test the condition of IC 555. 555 timer circuit tester, in principle, start the timer 555 in astable multivibrator mode. As an indicator of the status of the timer 555 good condition or damaged to use 2 pieces LED which will light up in a blink alternately when the timer 555 in good condition. And only one will turn on or off all the timer 555 when the condition is broken. 555 timer circuit tester is powered using 9 Volt DC voltage source.

Complete circuit tester 555 as follows.

How to use 555 timer tester is in conjuction with IC 555 to test the existing IC socket according to the order button. Then activate the power switch to begin testing the 555 timer ic. Then live we observe the LED indicators 2 before, whether flashing alternately (good) or not blink or even die all (timer 555 damaged).

RF Amplifier IC

RF amplifier IC is a type of electronic amplifier used to convert low-power radio frequency signal into a larger signal strength is important, usually for driving a transmitting antenna. This is usually optimized for high-efficiency, high output power (P1dB) of compression, loss of income on the input and output, better benefits, and optimal heat dissipation.

RF Amplifier IC

To make our amplifiers can also use transistors or IC OP Amp. In the op amp is actually a transistor that is in the form of a series so its easier to use.

Suppose that is used in the amplifier IC Op Amp 741 is a monolithic high performance electronic components that use Fairchild epitacial process. IC Op Amp 741 is an IC in which packed a differential circuit. The data sheet of IC Op Amp 741.
