The LTC^®1096/LTC1096L/LTC1098/LTC1098L are micropower, 8-bit A/D converters that draw only 80µA ofsupply 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 have both 3V (L) and 5V versions. These 8-bit, switched-capacitor, successive approxi mation ADCs includesample and  hold .TheLTC1096/LTC1096L have a single differential analog input. The LTC1098/LTC1098L offer 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 emote location possible and facilitates transmitting data through isolation barriers.

These circuits of LTC1096 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.
