I2C or SPI to vary the voltage from 0 to 10VDC?
Actually, I think LM317 type v.regs can go as low as 1.2V, with the reference pin grounded.If you want lower, try putting a 1N400x diode in series with the Vout pin.
Hi all, any other option? Is there really a chip that does the job? Just curious and wanna find out
