CVIn

[NaturalGeek]

Hi all,

i would like to read CV.

in theory this is achievable with the ainser64. but only from 0-5V. I need -15 - +15v

Is there a simple solution for this?

 

thx

Hi

op amp with a gain around -15dB (30vpp-->5vpp) with also 2,5v offset (-2,5v/+2,5v-->0v/5V), in this case you have to use negative feedback for gain, scaling will be +15-->0 and -15-->5, but you can invert again at soft side.

What is your CV out device? is the +/-15 CV rail to rail?
