ADA4500-2ARMZ Datasheet PDF - ADI

●The ADA4500-2ARMZ is a low power dual Operational Amplifier with rail-to-rail input and output swings. 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.
