AD8608 Op Amp IC Chip

AD8608(Precision, Low Noise, CMOS, Rail-to-Rail,Input/Output Operational Amplifiers)

Introduction

The AD8605, AD8606. and AD8608 are single, dual, and quad rail-to-rail input and output, single-supply amplifiers. They feature very low offset voltage,low input voltage and current noise, and wide signal bandwidth. They use the Analog Devices, Inc. patented DigiTrim® trimming technique, which achieves superior precision without laser trimming.

The combination of low offsets, low noise, very low input bias currents, and high speed makes these amplifiers useful in a wide variety of applications. Filters, integrators, photodiode 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 optical control loops, portable and loop-powered instrumentation, and audio amplification for portable devices.

The AD8605, AD8606, and AD8608 are specified over the extended industrial temperature range (-40°C to +125°C). The AD8605 single is available in 5-1ead SOT-23 and 5-ball WLCSP packages. The AD8606 dual is available in an 8-lead MSOP, an 8-ball WLSCP, and a narrow SOIC surface-mounted package.The AD8608 quad is available in a 14-1ead TSSOP package and a narrow 14-1ead SOIC package. The 5-ball and 8-ball WLCSP offer the smallest available footprint for any surface-mounted
operational amplifier. The WLCSP, SOT-23, MSOP,and TSSOP versions are available in tape-and-reel only.
