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.
