Hi,

We are using an IDAC at constant current, while the output current is switced from load to load using analog multiplexer (internal).

In some cases the load is not connected.

Is there a spice model for the Psoc IDAC to enable us to simulate the response of the IDAC ?

Hi

We do not have the Spice modle for PSoC 5 LP based IDAC.

According to the datasheet, the maximum settling time to 0.5LSB is 125ns for load of 600Ω/15-pF. This can be used if your load is within the limit.

Please let us know if the load is within 600Ω.

Thanks and regards
