AD8618ARU

Precision 20 MHz CMOS Rail-to-Rail Input/Output Operational Amplifiers Preliminary Technical Data AD8615/AD8616/AD8618 FEATURES Low Offset Voltage: 80µV typ. 300 µV max Single-Supply Operation: 2.7 to 6 Volts Low Noise: 8 nV/√Hz Wide Bandwidth: 20 MHz Slew Rate: 12 V/µs Low Distortion No Phase Reversal Low Input Bias Currents Unity Gain Stable APPLICATIONS Barcode Scanners Battery Powered Instrumentation Multi-pole Filters Sensors ASIC Input or Output Amplifier Audio Photodiode amplification GENERAL DESCRIPTION The AD8615, AD8616 and AD8618 are single, dual and quad rail-to-rail input and output single supply amplifiers featuring very low offset voltage, wide signal bandwidth, and low input voltage and current noise. These amplifiers use a patented trimming technique that achieves superior precision without laser trimming. All are fully specified to operate from +3V to +5V single supply. The combination of low offsets, low noise, very low input bias currents, and high speed make these amplifiers useful in a wide variety of applications. Filters, integrators, photo-diode amplifiers 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. Applications for these amplifiers include Portable and looppowered instrumentation, audio amplification for portable devices, portable phone headsets, bar code scanners, and multi-pole filters. The ability to swing rail-to-rail at both the input and output enables designers to buffer CMOS ADCs, DACs, ASICs and other wide output swing devices in single supply systems. The AD8615, AD8616 and AD8618 are specified over the extended industrial (-40° to +125°C) temperature range. The AD8615, single, is available in the tiny 5-lead SOT-23 package. The AD8616, dual, is available in the 8-lead microSOIC and narrow SOIC surface mount packages. The REV. PrA Information furnished by Analog Devices is believed to be accurate and reliable.
