The LTC1285/LTC1288 are 3V micropower, 12-bit, successive approximation sampling A/D converters. They typically draw only 160µA of supply current when converting and automatically power down to a typical supply current of 1nA whenever they are not performing conversions. They are packaged in 8-pin SO packages and operate on 3V to 6V supplies. These 12-bit, switched-capacitor, successive approximation ADCs include sample-and-holds. The LTC1285 has a single differential analog input. The LTC1288 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 (to 1.5V full scale) allow direct connection to sensors and transducers in many applications, eliminating the need for gain stages.
