Device Supply Ratiometry Application Circuit
Figures 2 and 3 present applications where the VCC pin is con-
nected together with the VREF pin of the A139x. Both of these
pins are connected to the battery, Vbat2. In this case, the device
output will be ratiometric with respect to the battery voltage.
The only difference between these two applications is that the
SLEEP pin in figure 2 is connected to the Vbat2 potential, so the
device is always in the active mode. In figure 3, the SLEEP pin is
toggled by the microprocessor; therefore, the device is selectively
and periodically toggled between active mode and sleep mode.
In both figures, the device output is connected to the input of an
A-to-D converter. In this configuration, the converter reference
voltage is Vbat1.
It is strongly recommended that an external bypass capacitor be
connected, in close proximity to the A139x device, between the
VCC and GND pins of the device to reduce both external noise
and noise generated by the chopper-stabilization circuits inside of
the A139x.
