The OPA129UE4 is an ultra-low bias current Difet? Operational Amplifier, using advanced geometry dielectrically-isolated FET (Difet?) inputs, this monolithic amplifier achieves a high performance level. Difet? fabrication eliminates isolation-junction leakage current, the main contributor to input bias current with conventional monolithic FETs. This reduces input bias current by a factor of 10 to 100. Very low input bias current can be achieved without resorting to small-geometry FETs or CMOS designs which can suffer from much larger offset voltage, voltage noise, drift and poor power supply rejection. The OPA129 special pin-out eliminates leakage current that occurs with other op-amps. Pins 1 and 4 have no internal connection, allowing circuit board guard traces.
