LTC1286/LTC1298

Micropower Sampling

12-Bit A/D Converters In

S0-8 Packages

DESCRIPTION

FEATURES

■

The LTC1286/LTC1298 are micropower, 12-bit, succes-

sive approximation sampling A/D converters. They typi-

cally draw only 250µA 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

5V to 9V supplies. These 12-bit, switched-capacitor, suc-

cessive approximation ADCs include sample-and-holds.

The LTC1286 has a single differential analog input. The

LTC1298 offers a software selectable 2-channel MUX.

12-Bit Resolution

■

8-Pin SOIC Plastic Package

■

Low Cost

■

Low Supply Current: 250µA Typ.

■

Auto Shutdown to 1nA Typ.

■

Guaranteed ±3/4LSB Max DNL

■

Single Supply 5V to 9V Operation

■

On-Chip Sample-and-Hold

■

60µs Conversion Time

■

Sampling Rates:

12.5 ksps (LTC1286)

11.1 ksps (LTC1298)

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

rangeofmicroprocessorsandmicrocontrollersoverthree

wires.This,coupledwithmicropowerconsumption,makes

remote location possible and facilitates transmitting data

through isolation barriers.

■

I/O Compatible with SPI, Microwire, etc.

■

^{3V Versions Availab}U ^{le: LTC1285/LTC1288}

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

transducersinmanyapplications, eliminatingtheneedfor

gain stages.
