FEATURES  
DESCRIPTIO  
The LTC®1408-12 is a 12-bit, 600ksps ADC with six  
simultaneously sampled differential inputs. The device  
draws only 5mA from a single 3V supply, and comes in a  
tiny 32 pin (5mm× 5mm) QFN package. A SLEEP shut-  
down feature further reduces power consumption to  
6µW. The combination of low power and tiny package  
makes the LTC1408-12 suitable for portable applications.

2.5V Internal Bandgap Reference, Can be Overdriven  
with External Reference  
3-Wire SPI-Compatible Serial Interface  
The LTC1408-12 contains six separate differential inputs  
that are sampled simultaneously on the rising edge of the  
CONV signal. These six sampled inputs are then  
converted at a rate of 100ksps per channel.

SLEEP (6µW) Shutdown Mode  
The 83dB common mode rejection allows users to  
eliminate ground loops and common mode noise by  
measuring signals differentially from the source.

Tiny 32-Pin (5mm × 5mm) QFN Package  
The device converts 0V to 2.5V unipolar inputs differen-  
tially, or ±1.25V bipolar inputs also differentially,  
depending on the state of the BIP pin. Any analog input  
may swing rail-to-rail as long as the differential input  
range is maintained.

Multiphase Motor Control  
The conversion sequence can be abbreviated to convert  
fewer than six channels, depending on the logic state of  
the SEL2, SEL1 and SEL0 inputs.
