DESCRIPTION
The OPA369 and OPA2369 are new low-power,
low-voltage operational amplifiers from Texas
Instruments designed especially for battery-powered
applications.
The OPAx369 operates on a supply voltage as low as
1.8V and has true rail-to-rail operation that makes it
useful for a wide range of applications. The
zero-crossover
feature resolves the problem of input
crossover distortion that becomes very prominent in
low voltage (< 3V), rail-to-rail input applications.
In addition to
microsize
packages and very low
quiescent current (1μA, max) the OPAx369 features
12kHz bandwidth, low offset drift (1.75μV/°C, max),
and low 0.1Hz to 10Hz noise (3.6μV
PP
).
The OPA369 (single version, available Q4 2007) is
offered in an SC70-5 package. The OPA2369 (dual
version) comes in both MSOP-8 and SOT23-8
packages.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may
degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond
those specified is not supported.
Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.5V beyond the supply rails should
be current limited to 10mA or less.
