Still on this old Gopher problem. Now have op amp NE5532NP, 8 pin DIL chip.
0-80mV PWM input and 220 Ohm 1mA fsd meter.
Will set gain at -2.5. Have 0-12V and 0-24V power avail.
have IC socket and small prefab cct board from Altronics.
8 or so 5K 1/8W resistors.
running out of data quota-pls advise chip pinout, do I need to provide center tapped Earth from power supply, which ps to use and a schematic--I've forgotten all this stuff. Zero error correction not required.
