GENERAL DESCRIPTION
The ADA4051-1 is a single CMOS, micropower, zero-drift
operational amplifier utilizing an innovative chopping
technique. This amplifier features rail-to-rail input and output
swing and extremely low offset voltage while operating from a
1.8 V to 5.5 V power supply. This amplifier also offers high
PSRR and CMRR, while operating with a supply current of only
13 μA per amplifier. This combination of features makes the
ADA4051-1 amplifier an ideal choice for battery-powered
applications where high precision as well as low power
consumption is important. The ADA4051-1 is specified for the
extended industrial temperature range of −40°C to +125°C. The
ADA4051-1 amplifier is available in the standard 5-pin SOT23
and 5-pin SC70.
