Functional Description
3.4.10 Bandgap Reference Circuitry
A Bandgap Reference Circuit provides a temperature stable reference voltage
for the device. A power down mode is available to switch off all subcircuits which
is controlled by the PWDN pin (Pin 27) as shown in the following table. The sup-
ply current drawn in this case is typically 50nA.
