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-multiplexed LCD display directly. 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.
