Notes: 4. 10 k
Ω, 100 pF load.
5. Tested in SM3, Slave sub-mode, 256 BPF.
6. 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.
7. No DC load.
8. Typical current: VA = 30mA, VD = 50mA with VD = 5.0V. VA = 30mA, VD = 35mA with VD = 3.3V.
Power supply current does not include output loading.
