  • Product introduction

The OPA129 is an ultralow bias current monolithic operational amplifier in 8-pin PDIP and SO-8 packages. Advanced geometric dielectrically isolated FETs（Difet®）input, this monolithic amplifier achieves a high level of performance.

DifetA major contributor to the manufacture of isolated junction leakage currents, input bias current FETs are monolithic to conventional monoliths. This will reduce the input bias from the current 10x to 100. Very low input bias currents can be achieved without resorting to small geometry FET or CMOS designs that can withstand greater offset voltage, voltage noise, drift, and poor power supply rejection.

The OPA129 is specially pinout to eliminate leakage current, which occurs with other op amps
