FIGURE 2. Equivalent Output Driver Circuit

3. Power Considerations

The SDM-CD16S power requirements may be large compared to most CSI

products. For most applications, an external power supply (see Figure 3) is

recommended to power the SDM-CD16S.

For some applications, it may be convenient to use the datalogger supply to

power the SDM-CD16S (see Figure 3). For long-term applications, the lead

acid power supply available with CSI dataloggers should be used, allowing the

batteries to be float charged. It is not recommended that the datalogger

alkaline supply be used to power the SDM-CD16S for long term applications.

If the datalogger lead acid supply is used, the current available from the wall

charger limits the SDM-continuous output current.
