LMH6738: Using LMH6738 with PSpice for TI: Help

Part Number: LMH6738

Hello, I'm learning how to use PSpice for TI and trying to model the LMH6738. 

Here is the symbol view:

Where are the other pins of the device, there are two more opamps on this device?

I must be doing something wrong?

Thank you

    Hello Joe,

      Thank you for trying out PSpice for TI!

      You are accessing the model correctly in this software. The pins on this model are labelled to match the pins on the device. Below image was snipped from the device's datasheet:

    • Pin 1: -INA 
    • Pin 2: +INA 
    • Pin 13: -Vs 
    • Pin 15: +Vs 
    • Pin 16: Channel A''s shutdown pin
    • Pin 14: Channel A's output pin

      All the pins for the first channel is modeled, but the other two channels, like you mentioned, are not. To simulate all three channels, please insert three of the same amplifier in the circuit. 

    Thank you,

    Sima
