The LTC

1594L/LTC1598L are 3V micropower, 12-bit

sampling A/D converters that feature 4- and 8-channel

multiplexers, respectively. They typically draw only 160µA

of supply current when converting and automatically

power down to a typical supply current of 1nA between

conversions. The LTC1594L is available in a 16-pin SO

package and the LTC1598L is packaged in a 24-pin

SSOP. Both operate on a 3V supply. The 12-bit, switched-

capacitor, successive approximation ADCs include a

sample-and-hold.

On-chip serial ports allow efficient data transfer to a wide

range of microprocessors and microcontrollers over three

or four wires. This, coupled with micropower consump-

tion, makes remote location possible and facilitates trans-

mitting data through isolation barriers.

The circuit 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.
