The AD8605, AD8606, and AD86081 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-lead 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-lead TSSOP package and  
a narrow 14-lead 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.
