3-1/2 Digit A/D Converter
High Accuracy, Low Power
Power Supplies
The AME7107 is designed to work from ±5V 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)
The low battery flag is set when the supply voltage (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 annuncia-
tor for AME7106; LB pin will be low (Ground)
for AME7107 and is capable to sink 8 mA to turn on a
LED indicator.
AME7107 Power Dissipation Reduction
The AME7107 sinks the LED display current and this
generates heat in the IC package. If the internal volt-
age reference is used, the fluctuating chip temperature
can cause the display to change reading. The AME7107
package power dissipation can be reduced by reducing
the LED common anode voltage.
A typical LED has 1.8 volts across it, at 7mA. When its
common anode is connected to +5V, the AME7107
