The LTC
廬
1594L/LTC1598L are 3V micropower, 12-bit
sampling A/D converters that feature 4- and 8-channel
multiplexers, respectively. They typically draw only 160碌A
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.
