AME7106/AME7106A/AME7106R AME7107/AME7107A/AME7107R 3-1/2 Digit A/D Converter High Accuracy, Low Power n Key Features l 100µV Resolution l High Impedance Differential Inputs l Differential Reference l Drive LCD (AME7106) or LED (AME7107) Directly l Four New Convenient Features (AME7106A/AME7107A) l Display-Hold l Low-Battery Indication l Integration Status Indication l De-Integration Status Indication n General Description The AME7106 and AME7107 family are high performance, 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 system, will drive non-multiplexed LCD display directly. The AME7107 is designed for a dual power supply system, will directly drive common anode LED display. These A/D converters are inherently versatile and accurate. 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. Display-hold, low-battery flag, integration and de-integration status flags are four additional features which are available in the 44-pin package, AME7106ACKW and AME7107ACKW. n Applications l Digital multimeter l pH meter l Capacitance meter l Thermometer l Digital Panel meter l Photometer n Typical O...
