Power Supply Requirements
The critical circuit voltages needed for operation of the SMU-
9000 are internally regulated. Therefore, any single ended DC
voltage power supply which can furnish from 6.5 to 30 volts at
20ma per channel may be used.
Note: Avoid using switching power supplies if high resolution
(low noise) output is required.
The output amplifier runs directly from the supply voltage
(positive) and an internally generated negative voltage. The
system can be calibrated to have an output voltage swing
anywhere from -5 volts to within 1.5 volts below the supply
voltage. Typical output voltage ranges and the required input
supply voltages are as follows:
Table 1. Output Voltage Range and Required Input Voltages for
the SMU-9000
Output Voltage Range Required Input Supply Voltage
-5 Vdc to +5 Vdc Requires a minimum 6.5 Volt
supply
0 Vdc to +10 Vdc Requires a minimum 11.5 Volt
supply
0.2 Vdc to 3.5 Vdc Requires a 5 Volt supply and
special 3.5 Volt internal requlator
to achieve minimum power drain
of 40 mW per channel
-10 Vdc to +10 Vdc
balanced differential Requires differential SMU-9200
with
±
5 Volt output from each
channel and a minimum 6.5 Volt
