Description

The OPA129UBE4 is an ultra-low bias current monolithic operational amplifier offered in an 8-pin PDIP and SO-8 package. 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. OPA129UBE4 Features • Ultra-low bias current: 100fa max• Low offset: 2mv max• Low drift: 10mv/°c max• High open-loop gain: 94db min• Low noise: 15nv/öhz at 10khz• Plastic dip and soic package OPA129UBE4 Applications • Photodetector preamp• Chromatography• Electrometer amplifiers• Mass spectrometer• Ph probe amplifier• Ion gage measurement
