ADA4051-1AKSZ-R7

ADA4051-1 is a CMOS, micropower, zero drift operational amplifier utilizing an innovative chopping technique. This amplifier feature rail-to-rail input/output swing and extremely low offset voltage while operating from a 1.8V to 5.5V power supply. In addition, these amplifiers offer high power supply rejection ratio (PSRR) and common-mode rejection ratio (CMRR) while operating with a typical supply current of 13μA per amplifier. This combination of features makes the amplifiers ideal choices for battery-powered application where high precision and low power consumption are important. Application includes pressure and position sensors, temperature measurements, electronic scales, medical instrumentation, battery-powered equipment, handheld test equipment.
