Hello,
Can anyone help me on my little project herein. I'm using an rail-to-rail operational sub-1V amplifier
NCS2001SQ2T1 (ON Semiconductors), for ampifying very low (mono) audio signal from an old reciever. Ampifyer is powered by single 1,4 button cell. Earphones are on output.
Since I'm still a beginer in electronics (or complete retard , I don't know which pin on the
NCS2001SQ2T1 should I connect with bat-, bat+, ear1, ear2, input1 and input2 contacts. Because of very small gabarits needed (therefore I use button cell), it is desirable the whole circuit has as minimum aditional components (SMD resistors and capacitors) as possible, regardeles the sound quality.
No volume potentiometers also; I need maximum output power that NCS2001 can provide. Simple as that. But not for me !
Btw:Could I use 2 or 3 IC-s for aditional amplification ?
I would very apriciate a simple scetch if possible. Thx.

IN FIRST PAGE OF DATA SHEET THER IS A SCHME WITH A BATERY .IN THIS SCHEME THE + OF BATERY IS THE PIN 5 VCC AND THE - OF BATERY IS THE PIN 2 VEE THE PIN 1 IS THE OUTPUT (EAR) AND THE PIN 3,4 IS THE INPUT 1,2.
TO ADJUST THE OUTPUT POWER PUT A POTENTIOMETER IN THE INPUT OF THO SIGNAL.
IF YOU NEED ADITIONAL AMPLIFICATION YOU MAY TO PUT IN YOUR PROJECT A POWER OUTPUT STAGE.
IF YOU WANT SEND YOR PROJET IN filossas@yahoo.gr TO SEE IT
