AD8601

Data Sheet Precision CMOS, Single-Supply, Rail-to-Rail, Input/Output Wideband Operational Amplifiers AD8601/AD8602/AD8604 FEATURES Low offset voltage: 500 µV maximum Single-supply operation: 2.7 V to 5.5 V Low supply current: 750 µA/Amplifier Wide bandwidth: 8 MHz Slew rate: 5 V/µs Low distortion No phase reversal Low input currents Unity-gain stable Qualified for automotive applications APPLICATIONS Current sensing Barcode scanners PA controls Battery-powered instrumentation Multipole filters Sensors ASIC input or output amplifiers Audio GENERAL DESCRIPTION The AD8601, AD8602, and AD8604 are single, dual, and quad rail-to-rail, input and output, single-supply amplifiers featuring very low offset voltage and wide signal bandwidth. These amplifiers use a new, patented trimming technique that achieves superior performance without laser trimming. All are fully specified to operate on a 3 V to 5 V single supply. The combination of low offsets, very low input bias currents, and high speed make these amplifiers useful in a wide variety of applications. Filters, integrators, diode amplifiers, shunt current sensors, and high impedance sensors all benefit from the combination of performance features. Audio and other ac applications benefit from the wide bandwidth and low distortion. For the most cost-sensitive applications, the D grades offer this ac performance with lower dc precision at a lower price point. Applications for these amplifiers include audio amplification for portable...
