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

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.
