LTC1408 6 Channel, 14-Bit, 600ksps Simultaneous Sampling ADC with Shutdown DESCRIPTIO The LTC®1408 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 6µW. 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.
