NOTES:
1. Write is defined as either any SBx and SW low or SGW is low. Chip Enable is defined as SE1 low, SE2 high, and SE3 low whenever ADSP
or ADSC is asserted.
2. All read and write cycle timings are referenced from K or G.
3. Tested per AC Test Load, Figure 2.
4. Measured at
± 200 mV from steady state.
5. This parameter is sampled and not 100% tested.
