LTC1408IUH-12#PBF Datasheet PDF - Linear Technology

●The LTC1408IUH-12#PBF is a 12-bit simultaneous sampling Analog-to-digital Converter (ADC) with shutdown. The device draws only 5mA from a single 3V supply and comes in a tiny 32 pin QFN package. A SLEEP shutdown feature further reduces power consumption to 6µW. The combination of low power and tiny package makes the LTC1408-12 suitable for portable applications. It 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 83dB common mode rejection allows users to eliminate ground loops and common mode noise by measuring signals differentially from the source. The conversion sequence can be abbreviated to convert fewer than 6-channel, 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.
