GENERAL DESCRIPTION
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 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.

Table 2. @ VS = 2.7 V, VCM = VS/2, TA = 25°C, unless otherwise noted.
ABSOLUTE MAXIMUM RATINGS
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those listed in the operational sections
of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.

Table 4. Package Type
θJA is specified for worst-case conditions, i.e., θJA is specified for device in
socket for PDIP packages; θJA is specified for device soldered onto a circuit
board for surface-mount packages.
ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on
the human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.
