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.
