Dear support team,

Could you tell me output range of Sawtooth module,please?

I think that output range of Sine tone module is -1~1.

But, range of Sawtooth module may be 0~1.

And could you write the information at Help file,please?

Best regards,

Takepiro

Hello Takepiro,

The ADAU1452's Sawtooth rises from 0 to +1, as shown on the Real-Time Display:

This differs from the ADAU1701 Sawtooth, which falls from +1 to -1

(it rises when viewed at a DAC output because the -1701's DACs invert):

I'm glad you asked, because I had no idea they were different until trying them.

Best regards,

Bob
