Precision CMOS Rail-to-Rail Input/Output Operational Amplifiers Preliminary Technical Data AD8615/AD8616/AD8618
FEATURES Offset Voltage: 80µV typ. Single-Supply Operation: Volts Noise: nV/Hz Wide Bandwidth: Slew Rate: V/µs Distortion Phase Reversal Input Bias Currents Unity Gain Stable APPLICATIONS Barcode Scanners Battery Powered Instrumentation Multi-pole Filters Sensors ASIC Input Output Amplifier Audio Photodiode amplification GENERAL DESCRIPTION AD8615, AD8616 AD8618 single, dual quad rail-to-rail input output single supply amplifiers featuring very offset voltage, wide signal bandwidth, input voltage current noise. These amplifiers patented trimming technique that achieves superior precision without laser trimming. fully specified operate from single supply. combination offsets, noise, very input bias currents, high speed make these amplifiers useful wide variety applications. Filters, integrators, photo-diode amplifiers high impedance sensors benefit from combination performance features. Audio other applications benefit from wide bandwidth distortion. Applications these amplifiers include Portable looppowered instrumentation, audio amplification portable devices, portable phone headsets, code scanners, multi-pole filters. ability swing rail-to-rail both input output enables designers buffer CMOS ADCs, DACs, ASICs other wide output swing devices single supply systems. AD8615, AD8616 AD8618 specified over extended industrial (-40° +125°C) temperature range. AD8615, single, available tiny 5-lead SOT-23 package. AD8616, dual, available 8-lead microSOIC narrow SOIC surface mount packages. REV.

CAUTION
(electrostatic discharge) sensitive device. Electrostatic charges high 4000 readily accumulate human body test equipment discharge without detection. Although this device features proprietary protection circuitry, permanent damage occur devices subjected high-energy electrostatic discharges. Therefore, proper precautions recommended avoid performance degradation loss functionality.
