Miscellaneous
RESET
Digital input. Take high to force device into
Power On Reset state, low to exit reset state.
TEST
Analog Output.
CMODE
Digital Input. Test mode, always tie high.
Analog Power Supplies (4 pins)
V
A
(2)
This is the positive supply pin for the analog
supply. It should be connected to a voltage
source of +5V and bypassed to AGND with a
0.1μF monolithic capacitor in parallel with a
10μF tantalum capacitor.
AGND (2)
This is the ground return for the analog sup-
ply.
Digital Power Supplies (17 pins)
V
D
(5)
This is the positive supply pin for the digital
supply. It should be connected to a voltage
source of +5V and bypassed to DGND with a
0.1μF monolithic capacitor.
V
DRAM
(3)
This is the positive supply pin for the digital
supply for the LM9831’s external DRAM I/O. It
also powers the A, B, A, and B stepper motor
outputs. It should be connected to a 3 or 5V
supply and bypassed to the closest DGND pin
with a 0.1μF monolithic capacitor.
DGND (9)
This is the ground return for V
D
and V
DRAM
.
