We are using a PSOC 4 CY8C42478ZI-MF485 and we need to generate an analog output voltage from 0 to 5 volts to control a motor controller. We are using the IDAC with a range of 0-612uA and externally we have a 10k resistor to have the voltage. However, the maximum voltage output we got was 4.3 volts. Thank you

I don't believe it is possible to reach 5V without using external components (Opamp / DAC). You may consider "PWM DAC" or R2R DAC instead, which can reach close to 5V (more likely about 4.9V).
