Figure 2. The ADA4500-2 Eliminates Crossover Distortion  
Across its Full Supply Range  
GENERAL DESCRIPTION  
The ADA4500-2 is a dual 10 MHz, 14.5 nV/√Hz, low power  
amplifier featuring rail-to-rail input and output swings while  
operating from a 2.7 V to 5.5 V single power supply. Compatible  
with industry-standard nominal voltages of +3.0 V, +3.3 V,  
+5.0 V, and 2.5 V.  
This combination of features makes the ADA4500-2 an ideal choice  
for precision sensor applications because it minimizes errors due to  
power supply variation and maintains high CMRR over the full  
input voltage range. The ADA4500-2 is also an excellent amplifier  
for driving analog-to-digital converters (ADCs) because the output  
does not distort with the common-mode voltage, which enables  
the ADC to use its full input voltage range, maximizing the  
dynamic range of the conversion subsystem.  
Employing a novel zero-crossover distortion circuit topology, this  
amplifier offers high linearity over the full, rail-to-rail input  
common-mode range, with excellent power supply rejection ratio  
(PSRR) and common-mode rejection ratio (CMRR) performance  
without the crossover distortion seen with the traditional  
complementary rail-to-rail input stage. The resulting op amp  
also has excellent precision, wide bandwidth, and very low  
bias current.  
Many applications such as sensors, handheld instrumentation,  
precision signal conditioning, and patient monitors can benefit  
from the features of the ADA4500-2.  
The ADA4500-2 is specified for the extended industrial temperature  
range (−40°C to +125°C) and available in the standard 8-lead  
MSOP and 8-lead LFCSP packages.
