GENERAL DESCRIPTION

The AD8603/AD8607/AD8609 are, single/dual/quad micro-
power rail-to-rail input and output amplifiers, respectively, that
features very low offset voltage as well as low input voltage and
current noise.
These amplifiers use a patented trimming technique that
achieves superior precision without laser trimming. The parts
are fully specified to operate from 1.8 V to 5.0 V single supply
or from ±0.9 V to ±2.5 V dual supply. The combination of low
offsets, low noise, very low input bias currents, and low power
consumption make the AD8603/AD8607/AD8609 especially
useful in portable and loop-powered instrumentation.
The ability to swing rail to rail at both the input and output
enables designers to buffer CMOS ADCs, DACs, ASICs, and
other wide output swing devices in low power single-supply
systems.
The AD8603 is available in a tiny 5-lead TSOT-23 package. The
AD8607 is available in 8-lead MSOP and SOIC packages. The
AD8609 is available in 14-lead TSSOP and SOIC packages.

Table 4. Package Characteristics


1 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.
2 Absolute maximum ratings apply at 25°C, unless otherwise noted. θJA is specified for the worst-case conditions, i.e., θJA is specified for device
soldered in 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 these parts feature
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.
