GENERAL DESCRIPTION
The ADA4500 is a dual 8.7MHz, 15 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.
Employing a novel circuit technology, these amplifiers offer zero input
crossover distortion (high linearity and excellent PSRR and CMRR
performance), precision, wide bandwidth and very low bias current.
This technology offer the excellent CMRR over the supply range without
the cross-over distortion seen with the traditional complementary input
stage.
This combination of these features makes the ADA4500 amplifier an
ideal choice for precision sensor applications as it minimizes errors due
to power supply voltage variations over the supply voltage and maintains
high CMRR even for a rail-to-rail input op amp. This results in excellent
performance for driving Analog-to-Digital (A/D) converters without
degradation of performance. The input common mode range includes
both the negative and positive supplies.
Sensors, handheld instrumentation, precision signal conditioning, and
patient monitors can benefit from the features of the ADA4500.
The ADA4500 is specified for the extended industrial temperature range
(−40°C to +125°C). ADA4500-2 dual amplifiers are available in the
standard 8-lead MSOP and LFCSP.
