Introduction: Portable Amplifier 10W for Cellphone, Etc

this is my first instructable.
PORTABLE AMPLIFIER 10W USING 9V 1100mAH BATERRY
, so please rate it :)

mine work great

Step 1: The Materials

R1 : 6 Ohm
R2 : 220 Ohm
R4 : 10 KOhm pontesiometer
C1 : 2200 uF / 25V
C2 : 470 uF / 16V
C3 : 470 uF / 16V
C4 : 100 nF
IC1 : TDA 2003
Heatsink for TDA 2003
Female jack: 2
male jack :1
9v 1100mAH battery
case
PCB
swicth

Step 2: Step 1

drill the case, and plug the male jack, female jack, swicth, potentiometer

Step 3: Step 2

connect the components, and then solder them.
make sure them are correctly

Step 4: Step 3

put the circuit at the case, and connect the male jack, female jack, swicth, potentiometer

Step 5: Finally

test it using 9v battery,
connect input jack to your phone, iPod, iPhone, cell phone, etc
connect output jack to headphone or speaker
rotate the potentiometer

mine work
i hope your own amplifier is work too

umm, sorry my english language, i'm indonesian

    nice one
    but
    1-did you built the circuit on any simulation software?or just did it directly on the board
    2-also that is this circuit from the datasheet? if not how did you manage to make it directly? please reply

    1. no. i got this circuit from electronic-lab.com.
    2. usually the circuit also can be found in the datasheet.

    sorry for late reply

    sorry for late reply

    Before constructing this i would like to ask a few questions.
    1)Will this work with a 12v power source?
    2)Can i use an AC power source with this amp?

    1. yes you can use 12v DC power source.
    2. if you want to use 12v AC power source you have to use bridge diode. to convert from AC to DC.
    but if you want to use 220v or 110v (or higher than 18v) you have to use an Adaptor. to convert from AC 220v or 110v to DC 12v.
