LMV842-Q1: Gain margin and Quiescent current

Part Number: LMV842-Q1

Hi,

Good day. I hope you are doing well.

Our customer is looking for the Gain margin and Quiescent current parameter for the LMV842-Q1. Can you please help us provide this? It seems that this parameter is not on the d/s.

Thank you.


Regards,

Cedrick

  • Hi Cedrick,

    Our customer is looking for the Gain margin and Quiescent current parameter for the LMV842-Q1.

    Quiescent current in LMV842-Q1 is approx. 1mA/channel.

    The gain margin is obtained via simulation. The simulation in buffer configuration is shown the phase margin at approx. 72 degree, which it matches the datasheet presented in Figure 20. So it is assumed that the simulation represents the LMV842-Q1 part, and the gain margin is measured at approx. -21.7 dB, shown in the buffer configuration below. 

    If you have additional questions, please let us know. 

    Best,

    Raymond
