ADA4807-4 Spice Model

Hi Theoderkaffee ,

Can you provide your expected output waveform values together with the sample Op Amp that you've tried with similar specification?

Regards,

JE

I used the ADA4891-4 as a replacement. Expected waveform is a triangular with a Vpp of 2.5V and an offset voltage of 2.5V (Vp+ ~ 3.75V and Vp- ~ 1.25V). Frequency is not that important but should be around 2kHz. I want to convert analog values to PWM to replace a lot of ADCs.

Regards. 

Hi,

Sorry for taking longer time to reply.

Please use the spice macro model on the product page for your simulation.

ADA4807 SPICE Macro Model

As seen on the screenshot above, the SPICE Macro model behavior is same as the expected values.

For instruction on how to apply the SPICE Macro model on LTspice software, kindly check the link below.

Hope that helps.
