Differential mode problem ADC_delsig Psoc 5 Kit-014 - Cypress.com Forums http://www.cypress.com/? Re: Differential mode problem ADC_delsig Psoc 5 Kit-014 http://www.cypress.com/?rID=79094 The PSOC 5 has IDAC, VDAC, 8 bits, and you can get higher resolution

with dithering -

You can also use a PWM folowed by RC LPF or integrator to get high resolution.

See attached ap note on approach. Settling time is an issue with this approach.

Ap note covers filter calculations.

 

Lastly if absolute accuracy, very hi res needed use PWM, say 16 bits, and monitor/correct

with DelSig. This is a control loop with all the attendant considerations, stability, settling

time, response, etc.. to design.

Re: Differential mode problem ADC_delsig Psoc 5 Kit-014 http://www.cypress.com/?rID=79091  HI MAAC,

I think it is better to start a new thread and PSoC5 does have DAC.
