General Description
The AME811 family are high performance, low power.
3-1/2 digit, dual-slope integrating A/D converters, with
on-chip display drivers. The AME811 is designed for a
single battery operated system, will drive non-multi-
plexed LCD display directly.
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.
Low-battery flag, integration and de-integration status
flags are three additional features which are available
in the 44-pin package, AME811ACKW.
