Simple slew-rate control is accomplished by adding a
capacitor from the gate to ground. The slew rate is
approximated by the RC charge curve of the pullup
resistor acting with the capacitor from gate to ground.
Note that the power-off is not well controlled due to the
absence of the 100Ω pulldowns.
Ensure that MOSFETs have a low gate-to-source
threshold (V

Bypass DBP and ABP each with a 1µF ceramic capacitor
to GND. Bypass V
Avoid routing digital return currents through a sensitive
analog area, such as an analog supply input return path
or ABP’s bypass capacitor ground connection. Use dedi-
cated analog and digital ground planes. Connect the
capacitors as close as possible to the device.
