SG2173P Op-Amp Class B. What can I use it for? Ideas?

lineup · 27th August 2008, 10:47 AM

I have a couple of 'bad' op-amps.

It is one 5 pin TO-220 power opamp. With max 3.5 Ampere output.
Same size and pins as for example LM1875/LM3875.

When I tried it for Audio output, it was a terrible crossover distortion

What possibly can I use it for.

Some sort of DC output power supply?
Voltage Regulated output maybe, using some Voltage reference at input?
Any ideas are welcome

Datasheet can no longer be found, but spec sheet say the following:

Quote:

Single General Purpose Op Amp - Pwr Op Amp,3.5A output current

Input Bias Current Max. (A)=1.0u
Unity Gain BW (Hz)=1.0M
V(io) Max. (V)=10 mV, offset

Com Mode Inp Range (VICR)= 15 Volt
P(D) Max.(W) Power Dissipation= 1.3 Watt (without heatsink)
Nom. Supp (V)=15 Volt
Package=TO-220
Pins=5

I am kidding of course.

Comparators - compare two voltages
Detection circuits - detect water levels, temperatures, or other uses
Oscillators - for power supply, speaker buzzers, or other uses
