Description
The XPTEK XPT2231/2/4 low-power chopper stabilized
operational amplifiers provide input offset voltage
correction for very low offset and offset drift over time
and temperature. The devices operate with a single
supply voltage as low as 1.8V, while drawing 34μA per
amplifier of quiescent current with a gain bandwidth
product of 350kHz. They are unity gain stable, have no
1/f noise, have good Power Supply Rejection Ratio
(PSRR) and Common Mode Rejection Ratio (CMRR),
and feature rail-to-rail input and output swing.
The devices were designed using an advanced CMOS
process. The XPT2231 (single version) is available in
SC70-5, SOT23-5 and SO-8 packages. The XPT2232
(dual version) is offered in MSOP-8 and SO-8 package.
The XPT2234 (quad version) is available in TSSOP-14
and SOIC-14 package. All versions are specified for
operation from -40°C to 125°C.

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.
