Hallo support team,
we want to use the DAC5662A in order to drive our outputsignal. The outputcurrent should be variable in a range of 20dB.
The outputcurrent is controlled by IOUTFS (IREF=32xVREF/RSET).
Is it possible to control this outputcurrent by an operational amplifier, which control the BIASJ_A and BIASJ_B outputcurrent ?
Do you have a suggestion about an regulation circuit?
We want to vary the outputcurrent from 2mA to 20mA (20dB).
Thank you in advance for answering my question.
Kind Regards
R. Thomas
