In figures 4 and 5, the microprocessor supply voltage determines
the ratiometric performance of the A139x output signal. As in the
circuits shown in figures 2 and 3, the device is powered by the
Vbat2 supply, but in this case, ratiometry is determined by the
microprocessor supply, Vbat1.
The S ¯ ¯ L ¯ ¯ E ¯ ¯ E ¯ ¯ P ¯ pin is triggered by the output logic signal from the
microprocessor in figure 5, while in figure 4, the S ¯ ¯ L ¯ ¯ E ¯ ¯ E ¯ ¯ P ¯ pin is
connected to the device power supply pin. Therefore, the device
as configured in figure 4 is constantly in active mode, while
the device as confiugred in figure 5 can be periodically toggled
Figure 4. Application circuit showing ratiometry of V
pin is tied to the microprocessor supply.
Figure 5. Application circuit showing device reference pin, VREF, tied to microprocessor supply. The device
sleep mode also is controlled by the microprocessor.

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.
