Notes:
3. Tested in SM3, Slave sub-mode, 128 BPF.
4. 10 kΩ, 100 pF load.
5. REFBUF load current must be DC. To drive dynamic loads, REFBUF must be buffered.
AC variations in REFBUF current may degrade ADC and DAC performance.
6. Typically current: VA = 30mA, VD = 50mA. Power supply current does not include output loading.
* Parameter definitions are given at the end of this data sheet.
