The TP2331/TP2332/TP2334 are single/dual/quad, low offset, low noise operational amplifiers with low power consumption and rail-to-rail input/output swing.

Input offset voltage is trimmed to less than 100μV and the CMOS inputs draw less than 0.3pA of bias current. The low offset drift, excellent CMRR, and high voltage gain make it a good choice for precision signal conditioning.

Each amplifier draws only 190μA current on a 3V supply. The micro power, rail-to-rail operation of the TP233x series is well suited for portable instruments and single supply applications.

The TP2331 is single channel version available in 8-pin SOP and 5-pin SOT23 packages. The TP2332 is dual channel version available in 8-pin SOP and MSOP packages. The TP2334 is quad channel version available in 14-pin SOP and TSSOP packages.
