Introduction. The Boyle, et al.1, SPICE macromodel for op amps has proven to be quite useful for fast and efficient computer- based IC circuit analysis, used When a high-speed comparator such as the LM111 is used with fast input signals and low source impedances, the out- put response will normally be fast and The LME49740 has almost identical audio performance and cost compared to the OPA1604, but it consumes nearly twice the quiescent current per channel.

High-fidelity audio systems may involve a significant number of operational amplifiers and any additional supply current consumption may increase
