General Description
The AME7106 and AME7107 family are high perfor-
mance, low power, 3-1/2 digit, dual-slope integrating A/
D converters, with on-chip display drivers. The
AME7106 is designed for a single battery operated sys-
tem, will drive non-multiplexed LCD display directly.
The AME7107 is designed for a dual power supply sys-
tem, will directly drive common anode LED display.
These A/D converters are inherently versatile and ac-
curate. They are immune to the high noise environ-
ments. The true differential high impedance inputs and
differential reference are very useful for making
ratiometric measurement, such as resistance, strain
gauge and bridge transducers. The built-in auto-zero
feature automatically corrects the system offset with-
out any external adjustments.
Display-hold, low-battery flag, integration and de-inte-
gration status flags are four additional features which
are available in the 44-pin package, AME7106ACKW
and AME7107ACKW.
