Hello.
I need an individually controllable 4-Channel 12bit DAC output.
It seems that only PSoC5800/5600 supports 4 x DAC. But it supports 8bit DAC.
1. Could you recommend the product?
2. Does PSoC4 or PSoC6 suport 4Ch DAC?
3. If I have to use 4 x 8bit DAC, do you recommend PSoC5 for this feature?
Thanks and Regards.
Solved! Go to Solution.

Hi,
PSoC 4 has an 8 bit DACs and a 7 bit DACs( PSoC4200 family has one 8bit DAC and one 7 bit DACs,PSoC4000S series has two 7 bit DACs). PSoC6 has one 12 bit DAC. PSoC5LP family has four 8 bit DACs.
1. So there are no PSoCs with four 12 bit DACs. If you want 4 channels PSoC5 might be the closest option.
2. Both of them does not have 4 channels.
3. PSoC5LP is the one seems to be closer to your requirement.

Depending on you application and accuracy, you could
- Change DAC voltage span for lower voltage signals
- Switch fast between 2 DAC values to get the value in-between with a hardware filter behind it
- Use a PWM-output with a hardware filter behind it
- When using current DACs, you can use 2 or more DACs in parallel
