功能描述

The LTC1096/LTC1098 are micropower, 8-bit A/D converters which draw only 80μA of supply current when converting. They automatically power down to 1nA typical supply current whenever they are not performing conversions. They are packaged in 8-pin SO packages and operate on 3V to 9V supplies. These 8-bit, switched-capacitor, successive approximation ADCs include sample-and-hold. The LTC1096 has a single differential analog input. The LTC1098 offers a software selectable 2-channel MUX.On-chip serial ports allow efficient data transfer to a wide range of microprocessors and microcontrollers over three wires. This, coupled with micropower consumption, makes remote location possible and facilitates transmitting data through isolation barriers.These circuits can be used in ratiometric applications or with an external reference. The high impedance analog inputs and the ability to operate with reduced spans (below 1V full scale) allow direct connection to sensors and transducers in many applications, eliminating the need for gain stages.All grades are specified with offset and linearity errors of ?0.5LSB maximum over temperature. The A grade devices are specified with total unadjusted error of ?0.5LSB maximum over temperature.
