FEATURES  
DESCRIPTIO  
The LTC®1594L/LTC1598L are 3V micropower, 12-bit  
sampling A/D converters that feature 4- and 8-channel  
multiplexers,respectively.Theytypicallydrawonly160µA  
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.Bothoperateona3Vsupply.The12-bit,switched-  
capacitor, successive approximation ADCs include a  
sample-and-hold.  
12-Bit Resolution on 3V Supply  
Low Supply Current: 160µA Typ  
Auto Shutdown to 1nA  
Guaranteed ±3/4LSB Max DNL  
Guaranteed 2.7V Operation  
(5V Versions Available: LTC1594/LTC1598)  
Multiplexer: 4-Channel MUX (LTC1594L)  
8-Channel MUX (LTC1598L)  
Separate MUX Output and ADC Input Pins  
MUX and ADC May Be Controlled Separately  
Sampling Rate: 10.5ksps  
On-chip serial ports allow efficient data transfer to a wide  
I/O Compatible with QSPI, SPI and MICROWIRETM, etc.  
Small Package: 16-Pin Narrow SO (LTC1594L)  
rangeofmicroprocessorsandmicrocontrollersoverthree  
or four wires. This, coupled with micropower consump-  
tion, makes remote location possible and facilitates trans-  
mitting data through isolation barriers.  
24-Pin SSOP (LTC1598L)  
U
APPLICATIO S  
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.
