The OPA330AIDBVR from Texas Instruments is a single-channel, 1.8V, 35uA, zero-drift CMOS operational amplifier with 50uV max offset voltage and 0.25uV\/C drift in a SOT-23-5 package. With rail-to-rail I\/O, internal EMI filtering, and near-flat 1\/f noise, it provides precision at the lowest power.<\/p>\n
