Gener ally, y ou have a fe w milli-am ps for you r circ uit.
You may be able to get more than this in your
circumstance.
Unfortuna tely, the only w ay to tell is to try it. The best
way to tell is to connect the devices to the board and load
the ± supplies. M easure the voltages. J10-18 should be
a t l ea st 7. 5 V , i f y o u w i ll us e t he 0 -5 V A / D a n d D / A
range. J10-20 should be about -5V.
An alternative is to put analog I/O in the 2.5V max.
range. Then use the + 5V supply for amplifier supply.
