47 / 72 page ![]() TLC225x, TLC225xA Advanced LinCMOS RAIL-TO-RAIL VERY LOW-POWER OPERATIONAL AMPLIFIERS SLOS176D – FEBRUARY 1997 – REVISED MARCH 2001 47 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 APPLICATION INFORMATION macromodel information Macromodel information provided was derived using MicroSim Parts , the model generation software used with MicroSim PSpice . The Boyle macromodel (see Note 5) and subcircuit in Figure 61 are generated using the TLC225x typical electrical and operating characteristics at TA = 25°C. Using this information, output simulations of the following key parameters can be generated to a tolerance of 20% (in most cases): D Maximum positive output voltage swing D Maximum negative output voltage swing D Slew rate D Quiescent power dissipation D Input bias current D Open-loop voltage amplification D Unity-gain frequency D Common-mode rejection ratio D Phase margin D DC output resistance D AC output resistance D Short-circuit output current limit NOTE 5: G. R. Boyle, B. M. Cohn, D. O. Pederson, and J. E. Solomon, “Macromodeling of Integrated Circuit Operational Amplifiers”, IEEE Journal of Solid-State Circuits, SC-9, 353 (1974).
