#15991 - RE: Low cost D/A converter |
Hi Per,
as Erik said, a PWM (pulse width modulator) was useful and the cheapest. Then a simple RC low pass filter convert the pulse width to a voltage. The T89C51RD2 has already 5-channel 8-bit PWM included. Also a timer interrupt can be used to build an 8-channel PWM in software. Peter |
