measurements should be limited to applications where cur-
rent sources are measured via shunts or where signal volt-
ages in the range of some volts are available.
Bus-Interface
As the outputs of the SDM are BUS compatible, only a few
ICs are necessary to interface to various BUS systems. For
such interfacing, 20-pin IC sockets are provided. Wiring is
by wire wrap to the BUS connector.
Setting of Various Modes
Circuit Board positions are provided for the connection of
‘jumpers’ as follows:
J1, J2—ADC analog input volt age settings.
J3—Set for differential (SDM8X3) or single ended
(SMD8X2) operation.
J4—Instrumentation amplifier gain settings.
(a) 16 input channels, single ended:
—Use SDM8X2
—Consider single-ended filtering
—Connect J3 (pin 66) to common
(b) Differential inputs
—Use SDM8X3
—Consider differential filtering
—Connect J3 (pin 66) to pin 67
(c) Analog input

(d) Gain of instrumentation amplifier
G = 1
Jumper J4 open
G = 10
Jumper J4 to pin 63
G = 100
Jumper J4 to pin 64
Other gains: use additional resistor between pin 62 and pin
63 (see section on Instrumentation Amplifier) as low tempco
resistor is recommended in order to minimize gain drift.
