Question:

What is the power up sequence for e2v-Grenoble ADC + DMUX?

Answer:

When using both e2v-Grenoble ADC and DMUX, the power up sequence for the devices is the following:

- First apply the VEE = –5V power supply;

- Second turn on VCC = +5V power supply;

- Afterwards, connect VPLUSD, if needed;

- VTT should be then supplied;

- Thereafter, you can apply the clock and the analog inputs;

- Finally, it is required to perform an asynchronous reset on the DMUX.

Note: In this sequence, the last two steps are mandatory in this specified order. Nevertheless, the first 4 steps are not critical.
