The LTC1408 is a 14-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 shutdown feature lowers power consumption to 6?W. The combination of low power and tiny package makes the LTC1408 suitable for portable applications.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.The 90dB common mode rejection allows users to eliminate ground loops and common mode noise by measuring signals differentially from the source.The device converts 0V to 2.5V unipolar inputs differentially, 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.The conversion sequence can be abbreviated to convert fewer than six channels, depending on the logic state of the SEL2, SEL1 and SEL0 inputs.The serial interface sends out the six conversion results in 96 clocks for compatibility with standard serial interfaces.Applications Multiphase Power Measurement Multiphase Motor Control Data Acquisition Systems Uninterruptable Power Supplies

Demonstration circuit DC2343A is a complete system level solution for a nanopower buck-boost DC/DC with integrated coulomb counter. The DC2343A contains a PIC16F1459 embedded processor for communication to the PC over USB and the LTC3335 via its I2C port. The GUI is capable of reading and writing all the control registers on the LTC3335 as well as displaying and resetting all its alarm registers. The firmware and software for the embedded system and the GUI are available at the LTC3335 solutions page.
