OPA828. New chip, good trial. It is a FET. It is good for small output DAC such as CS43198. Signal drop will not be big.
OPA828 is a single circuit opamp. It is quite difficult to put 4 pcs. on FA3S. Complicated SMT dual to single convertor is required. Good hot gun technique is required too.
Is FA3S big enough with it? |
