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.
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.
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.
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.
