Description

The OP15EJ is an electronic component model belonging to the IC Chips product category. It is part of the ADI-JFET input series of devices that offer advantages over industry-generic devices in terms of cost and performance. These devices have offset voltages as low as 0.5 mV with temperature coefficient of voltage offset (TCVOS) guaranteed to be 5 μV/°C. The OP15EJ features a unique input bias cancellation circuit that reduces the input bias current (IB) by a factor of 10 compared to conventional designs. ADI specifies the IB and input offset current (IOS) with the devices warmed up and operating at 25°C ambient temperature.
