AD8605 utilizes patented DigiTrim technology to achieve superior precision without laser trimming. The combination of very high performance features makes these amplifiers useful in a wide variety of applications. Filters, integrators, photo-diode amplifiers and high impedance sensors all benefit from the performance of the AD8605. Audio and other AC applications benefit from the wide bandwidth and low distortion. Applications for these amplifiers include laser diode control loops and optical sensing, portable and loop-powered instrumentation, audio amplification for portable devices and ASIC input/output amplifiers. The AD8605ACB is specified over the extended industrial (-40° to +125°C) temperature range. The AD8605ACB is available in the tiny 5-bump MicroCSP package and offers the smallest available footprint for any surface-mountable operational amplifier. MicroCSP versions are available in tape and reel only. Refer to the AD8605/AD8606/AD8608 family datasheet for the released AD8605 version in SOT package and for dual/quad versions.
