| Jan 27, 2019 at 14:01 | comment | added | Noel | Thank you Spehro. Digitally the DC offset will be zeroed using a low pass filter. So having it spot on the middle is not critical for now. If accurately setting the 2.5V becomes a requirement should a LM4040 be more suitable as a reference (than Vcc/2)? | |
