i have to design a circuit diagram for the following requirements:
-power in 9Vdc, power out +/- 5 Vdc at 150 ma
solution: im not sure yet, maybe use two op amps ?
edit: im going to use two regualtors that take the 9Vpp input and turn it into a +/- 5Vdc output
- power off after 5 minutes
solution: have this part done using a 555 timer in monostable
- gain channel 12Vp-p Vout = 0-3Vdc
solution: so im thinking of using a rectifier then having a summation op amp with a potentiometer to vary from 0-3 volts.
extra add ons--
- an amp with vin 12 Vpp and vout 5Vpp adjustable
- also how can i change the mono stable timer so when its dark, it decreases from 5 mins to 2 minutes
