Description
The XPT2291(E) is a high precision,ultra-low power...
CMOS op-amp featuring a maximum supply current
of 900 nA with an ultra-low typical input bias current
of 1 fA. Analog trim and calibration routine reduce
input offset voltage to below 600 μV, and the
precision temperature compensation technique
makes offset voltage temperature drift at 0.4 μV/°C,
which allowing use of the XPT2291(E) in systems
with high gain without creating excessively large
output offset errors.
The XPT2291(E) is unity gain stable with a constant
18 kHz GBWP, 10 mV/μs slew rate, which make
them appropriate for low frequency applications,
such as battery current monitoring and sensor
conditioning. The XPT2291(E) can operate from a
single-supply voltage of +1.8V to +6.0V or a
dual-supply voltage of ±0.9V to ±3.0V. Beyond the
rails input makes it very prominent in low voltage (<
3V) rail-to-rail input applications.
The combined features make the XPT2291(E) an
ideal choice for battery-powered applications
because it minimize errors due to power supply
voltage variations over the lifetime of the battery and
maintain high CMRR even for a rail-to-rail input
op-amp. Mobile accessories, wireless remote
sensing, backup battery sensors, and single-Li+ or
2-cell NiCd/Alkaline battery powered systems can
benefit from the features of the XPT2291(E) op-amp.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any Absolute Maximum
Rating condition for extended periods may affect device reliability and lifetime.
Note 2: The inputs are protected by ESD protection diodes to each power supply. If the input extends more than 500mV beyond the power supply, the input
current should be limited to less than 10mA.
Note 3: A heat sink may be required to keep the junction temperature below the absolute maximum. This depends on the power supply voltage and how many
amplifiers are shorted. Thermal resistance varies with the amount of PC board metal connected to the package. The specified values are for short traces
connected to the leads.
