GENERAL DESCRIPTION  
The ADA4051-1/ADA4051-2 are CMOS, micropower, zero-  
drift operational amplifiers utilizing an innovative chopping  
technique. These amplifiers feature rail-to-rail input/output  
swing and extremely low offset voltage while operating from a  
1.8 V to 5.5 V 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 13 μA per amplifier. This combination of features  
makes the ADA4051-1/ADA4051-2 amplifiers ideal choices for  
battery-powered applications where high precision and low  
power consumption are important.  
The ADA4051-1/ADA4051-2 are specified for the extended  
industrial temperature range of −40°C to +125°C. The ADA4051-1  
amplifier is available in 5-lead SOT-23 and 5-lead SC-70 packages.  
The ADA4051-2 amplifier is available in 8-lead MSOP and 8-lead  
LFCSP packages.  
The ADA4051-1/ADA4051-2 are members of a growing series  
of zero-drift op amps offered by Analog Devices, Inc. Refer to  
Table 1 for a list of these devices.
