Remote battery-powered sensors, handheld instrumentation  
and consumer equipment, hazard detectors (for example, smoke,  
fire, and gas), and patient monitors can benefit from the features  
of the ADA4505-2/ADA4505-4 amplifiers.  
GENERAL DESCRIPTION  
The ADA4505-2/ADA4505-4 are dual and quad micropower  
amplifiers featuring rail-to-rail input and output swings while  
operating from a single 1.8 V to 5 V power supply or from dual  
0.ꢀ V to 2.5 V power supplies.  
The ADA4505-2/ADA4505-4 are specified for both the industrial  
temperature range (−40°C to +85°C) and the extended industrial  
temperature range (−40°C to +125°C). The ADA4505-2 dual  
amplifier is available in standard 8-lead MSOP and 8-ball WLCSP  
packages. The ADA4505-4 quad amplifier is available in a 14-lead  
TSSOP package.  
Employing a new circuit technology, these low cost amplifiers  
offer zero input crossover distortion (excellent PSRR and CMRR  
performance) and very low bias current, while operating with a  
supply current of less than 10 μA per amplifier.  
This combination of features makes the ADA4505-2/ADA4505-4  
amplifiers ideal choices for battery-powered applications because  
they minimize errors due to power supply voltage variations  
over the lifetime of the battery, and maintain high CMRR even  
for a rail-to-rail op amp.  
The ADA4505-2/ADA4505-4 are members of a growing series  
of zero crossover op amps offered by Analog Devices, Inc.,  
including the AD8506/AD8508, which also operate from a  
single 1.8 V to 5 V power supply or from dual 0.ꢀ V to 2.5 V  
power supplies.
