OPA333A-EP, , OPA2333A-EP SGLS383B – APRIL 2007 – REVISED JUNE 2008 ............................................................................................................................................................ DESCRIPTION/ORDERING INFORMATION The OPA333A series of CMOS operational amplifiers uses a proprietary auto-calibration technique to simultaneously provide very low offset voltage (10 V max) and near-zero drift over time and temperature. These miniature, high-precision, low-quiescent-current amplifiers offer common-mode range 100 mV beyond the rails, and rail-to-rail output that swings within the rails. Single or dual supplies as low as 1.8 V (± ...
