Pyle 2-CH AMP SPEAKER SYSTEM$76.92. Why would anyone want an integrated circuit (IC) without transistors? Apparently it's an offset nulling resistor array, described in The IC Op-amp Cookbook. A circuit simulation to get a better understanding of how it works, maybe sweep the value of R354. I assume I would have to tweak some resistor values in order to make the circuit run at this lower supply . The IC Op-Amp Cookbook is a wonderful tool. (And if you take time to read the introduction, he actually does give you a compressed version of what the design abstractions are that make op-amps so useful. Now that we have your attention, we are trying to make a point. The Perfect and Practical Op Amp. A BiCMOS IC without transistors, that's different! ROHM IC 8-PIN DIP DUAL OP AMP$0.6. The original circuit runs on 12 VDC, but since the A/D converter IC must be supplied with 5 VDC only I want to scale down the circuit, so that 5 V is the maximum voltage present.
