GENERAL DESCRIPTION  
The ADA4528-1/ADA4528-2 are ultralow noise, zero-drift  
operational amplifiers featuring rail-to-rail input and output  
swing. With an offset voltage of 2.5 μV, offset voltage drift of  
0.015 μV/°C, and typical noise of 97 nV p-p (0.1 Hz to 10 Hz,  
AV = +100), the ADA4528-1/ADA4528-2 are well suited for  
applications in which error sources cannot be tolerated.  
10  
The ADA4528-1/ADA4528-2 have a wide operating supply range  
of 2.2 V to 5.5 V, high gain, and excellent CMRR and PSRR  
specifications, which make it ideal for applications that require  
precision amplification of low level signals, such as position and  
pressure sensors, strain gages, and medical instrumentation.
