• Manufacturer Part Number: ame7106
• Description: 3-1/2 Digit A/d Converter High Accuracy, Low Power
• Manufacturer: AME, Inc.

Power Supplies
However, if a negative supply is not available, it can be
generated from the clock output with two diodes, two
capacitors, and an inexpensive IC. The 7660 DC to DC
converter may also be used to generate -5V from +5V.
Low Battery Flag (LB)
(V+ to V-) is lower than seven volts, typical. Once the LB
is set, the waveform of the LB will be out of phase with
the BP (Back Plane) to turn on a low battery annunciator
for AME7106; LB pin will be low (Ground)

The AME7107 is designed to work from +5V supplies.
The low battery flag is set when the supply voltage

reference is used, the fluctuating chip temperature can
cause the display to change reading. The AME7107 pack-
