analog Connections
Analog signal connections are made via the row of turret
posts along the edge of the board. Also, when connecting
the board to an existing circuit the exposed ground planes
along the edges of the board may be used to form a solid
connection between grounds.
GND – (8 turrets) These turrets are connected directly to
the internal ground planes.
EXTV
CC
– This turret allows the user to provide power to
the LTC2991. Select power jumper accordingly.
V1, V2, V3, V4, V5, V6, V7, V8 – These turrets are used to
provide input voltage to the monitor when the correspond-
ing jumpers are set to the VOLT position.
Digital Connections
PWM – PWM output pin configurable through the QuikEval
software. State of the PWM pin is reflected quantitatively
through the PWM LED at D2.
SDA, SCL – I
2
C signals brought out to turrets. If DC1785B is
to be run without a DC590 connected or with an alternative
microprocessor, I
2
C signals can be driven at these points.
If DC590 is not used R4 and R5 (Backside of board) can
be populated with appropriate I
2
C pull-up values.
GPO – General purpose output pin can be toggled through
QuikEval software.
