The LTC

®1285/LTC1288 are 3V micropower, 12-bit, suc-

cessive approximation sampling A/D converters. They

typically draw only 160

µA of supply current when con-

verting and automatically power down to a typical supply

current of 1nA whenever they are not performing conver-

sions. 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.
