3-1/2 Digit A/D Converter - Low Power  
With HOLD And Differential Reference Inputs  
AME811/AME811A/AME811R  
n Key Features  
n General Description  
l 100µV Resolution  
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.  
l High Impedance Differential Inputs  
l Differential Reference  
l Drive LCD Directly  
l Three New Convenient Features  
(AME811A Only)  
l Low-Battery Indication  
l Integration Status Indication  
l De-Integration Status Indication  
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.  
n Applications  
l Digital multimeter  
l pH meter  
l Capacitance meter  
l Thermometer  
l Digital Panel meter  
l Photometer  
Low-battery flag, integration and de-integration status  
flags are three additional features which are available  
in the 44-pin package, AME811ACKW.  
* For the operating circuit of the reverse-pins version, please refer to  
pin configuration on page 4 and pin description on page 5 & 6.
