The external output analog voltage conversion circuit of DAC0832

Published:2013/1/23 2:29:00 Author:Ecco | Keyword: external output, analog voltage conversion

DAC0832 is a current output converter, if you need to get the analog voltage output, you must add an external converter circuit. The figure shows an analog voltage output circuit composed of two-stage operational amplifier. Unipolar analog voltage is output from the point a , and bipolar analog voltage is output from point b. If the reference voltage is +5 V, the point of a outputs 0 -5V voltage, and point b outputs ± 5V voltage.   (View)
