AD8605ARTZ-REEL7

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 Analog Devices’ 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 the 5-lead SOT-23 and 5-bump MicroCSP packages. The 5-bump MicroCSP offers the smallest available footprint for any surface-mount operational amplifier. The AD8606 dual is available in an 8-lead MSOP package and a narrow SOIC surface-mount package. The AD8608 quad is available in a 14-lead TSSOP and a narrow 14-lead SOIC package. MicroCSP, SOT, MSOP, and TSSOP versions are available in tape and reel only.
