LTC1096L

The LTC®1096L/LTC1098L are 3V micropower, 8-bit successive approximation sampling A/D converters. They typically draw only 40mA of supply current when converting and automatically power down to a typical supply current of 1nA between conversions. They are packaged in 8-pin SO packages and operate on a 3V supply. These 8-bit, switched capacitor, successive approximation ADCs include a sample-and-hold. The LTC1096L has a single differential analog input. The LTC1098L offers a software selectable 2-channel multiplexed input.

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.

The circuits of LTC1096L can be used in ratiometric applications or with an external reference. The high impedance analog inputs and the ability to operate with reduced spans (to 1V full scale) allow direct connection to sensors and transducers in many applications, eliminating the need for gain stages.
