The OPA2335 CMOS operational amplifier uses auto-zeroing techniques to simultaneously provide very low offset voltage (5 µV max), and near-zero drift over time and temperature. This high-precision, low quiescent current amplifier offers high input impedance and rail-to-rail output swing. Single or dual supplies as low as 2.7 V (±1.35 V) and up to 5.5 V (±2.75 V) may be used. This op amp is optimized for low-voltage, single-supply operation.

The OPA2335 is available in a CDIP-8 package and is specified for operation from -55°C to 125°C.
