AD820 spice model

Hello

 

I think that AD820 spice model does not include temperature charachtristcs.

Is it correct ?

 

Our customer  uses AD820 spice simulation (using LTspice)

 but the  current consumption in simulation result is 2ma@ 25 degree celcius and  ~9mA @ 85 degree celcius.

( load 10Kohm,  output voltage 10V.  gain = 1+9Kohm/1Kohm=10)

 

The datasheet says that current consumption at no load is 900uA maximum value and this value is too big.

So, I think that AD820 spice model does not include temperature characteristics..

 

Please let me know your adivice.

 

Regards,

Terumas
