FEATURES
l 100µV Resolution 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 n GENERAL DESCRIPTION
3-1/2 digit, dual-slope integrating A/D converters, with on-chip display drivers. They are immune to the high noise environments. 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 without 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. n APPLICATIONS
l Digital multimeter l pH meter l Capacitance meter l Thermometer l Digital Panel meter l Photometer n Typical Operating Circuit * For the operating circuit of the reverse-pins version, please refer to pin configuration on page 4 and pin description on page 5 & 6.
