FEATURES  
DESCRIPTIO  
The LTC®1408 is a 14-bit, 600ksps ADC with six simulta-  
neously 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 shutdown  
feature lowers power consumption to 6µW. The combina-  
tion of low power and tiny package makes the LTC1408  
suitable for portable applications.

100ksps Throughput per Channel  
■
76dB SINAD  
■
Low Power Dissipation: 15mW  
■
3V Single Supply Operation  
■
2.5V Internal Bandgap Reference, Can be Overdriven  
with External Reference  
3-Wire Serial Interface  
The LTC1408 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.

Internal Conversion Triggered by CONV  
■
SLEEP (6µW) Shutdown Mode  
■
NAP (3.3mW) Shutdown Mode  
The 90dB common mode rejection allows users to  
eliminate ground loops and common mode noise by  
measuring signals differentially from the source.  
■
0V to 2.5V Unipolar, or ±1.25V Bipolar Differential  
Input Range  
■
90dB Common Mode Rejection  
■
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.
