[sdiy] free AS3320, AS3340, AS3310 and AS3360 samples

[Terry Shultz]

Hi Paula,

Post just deliver my AS3320, AS3340, AS3310 and AS3360 devices.

All but the AS3320 were in Ceramic packages.

I’ll have a small board done in about a week to put them into for evaluation and measurement.

The SSM2044 LPF appears to be priced about the same , so you choose your favorite 4Pole LP device.

regards,

Terry
