ADuC7033
ADC GROUND SWITCH
The ADuC7033 features an integrated ground switch pin,
GND_SW, Pin15. This switch allows the user to dynamically
disconnect ground from external devices. It allows either a
direct connection to ground, or a connection to ground using a
20 kΩ resistor. This additional resistor can be used to reduce the
number of external components required for an NTC circuit.
The ground switch feature can be used for reducing power
consumption on application specific boards.
An example application is shown in Figure 19.

Figure 19. Example External Temperature Sensor Circuits
This diagram shows an external NTC used in two modes, one
using the internal 20 kΩ resistor, and the second showing a
direct connection to ground, via the GND_SW.
