High-precision analog-to-digital conversion chip - MS5194T

MS5194T/MS5195TLow-power, low-noisesix-channel differential input24bit/16bitAnalog-to-digital converter. It integrates internallyLow-noise input buffer, low-noise instrumentation amplifier, precision low-noise, low-drift internalThe bandgap reference can also use an external differential reference voltage. The chip also integrates programmableExcitation current source,burnoutCurrent source and bias voltage generator. The bias voltage generatorcan set the common-mode voltage of the channel to0.5*AVDD。This chip uses an external clock or internal clock, and the output data rate can be set through softwareSet the data update rate to4.17Hzto470Hz. The power supply voltage range is2.7Vto5.25V。MS5194T/MS5195TAdoptsTSSOP24 package.
