Spice Model AD8624 OK?

Hello,

When I simulate the AD8624 with a 500 Ohm load resistor, the output is limited to 0.4V.

The circuit is a differential amplifier with gain 1 using 10kOhm resistors plus a 500Ohm load.

The design will have only +/-5 supply voltage.

I have attached a PSPICE netlist.

I found it's necessary to rise the supply voltage to +/-6.5V to get +/-2V output voltage with a 500Ohm load.

Is the mdodel wrong or can't deliver the AD8624 +/-2V with a 500Ohm load when using a +/-5V supply?

Unfortunately there is no specification or typical curve about max. output voltage versus load current.

Best regards,

Helmut
