SPICE MODEL of uPC324C in SPICE PARK
0 likes365 views
The document provides a device modeling report for an operational amplifier with part number UPC324C from manufacturer NEC Electronics. It includes simulation results that characterize the op-amp's output voltage swing, input offset voltage, slew rate, input bias current, open loop voltage gain, output short circuit current, and common mode rejection ratio. The simulations compare measured values from the op-amp datasheet to verify the accuracy of the developed SPICE model.
