Title: Op-Amp circuit design help needed - unity gain and max 4 V output power Post by hendrik on Sep 23rd, 2011, 3:28am Hi, I would like to design an additive op-amp circuit with two voltages, one gained by 1 and the other gained by 3. The supply voltages dont matter, I have anything. The input voltages are AC 1Vpp that should be AC 3Vpp at the output (gain 3) and an additiv bias that should be gained with unity gain to -1.8V. The frequency behaviour should be quite linear up to some MHz. The cutoff frequency can be around 10 KHz, or much higher, this doesnt matter. I've looked in some datasheets (OPA 600 for example) but I could find the right OP-Amp so far. Can anybody tell me which one could fit? sheap ones ore expensive ones - doesnt matter, they just should be available somehow. Kind Regards, Hendrik |
