LTC1408

6 Channel, 14-Bit, 600ksps

Simultaneous Sampling ADC

with Shutdown

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.

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 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.

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.
