EVAL-ADA4870 Asymmetric Supply 0
Not Answered

I have purchased a EVAL-AD4870 board. My application requires asymmetrical supplies: i.e. VCC=38V and VEE=-2V so that signals in the 0-36V range can be covered in a non-inverting configuration. I also need to generate very low frequency (i.e. sub-kHz...
