(1)

All static performance tests (except IOUT) are performed in a closed-loop system using an external precision OPA277 I-to-V converter

amplifier. The DAC8812 RFB pin is tied to the amplifier output. Typical values represent average readings measured at 25°C.

(2)

These parameters are not subject to production testing.
