The AD705 is a low power bipolar op amp that has the low input bias current of a BiFET amplifier but which offers a significantly lower IB drift over temperature.
The AD705 is a low power bipolar op amp designed for precision applications such as low frequency active filters, precision instrumentation, and high quality integrators. It combines the low input bias current characteristics of BiFET amplifiers with the low drift and noise performance of bipolar amplifiers using superbeta bipolar input transistors.
| Input Bias Current (Max) | 600 pA |
|---|---|
| Offset Voltage Drift (Max) | 0.6 mV/8C |
| Power Supply Current (Max) | 600 mA |
| Unity Gain Crossover Frequency | 800 kHz |
The AD705 is available in 8-Pin Plastic Mini-DIP, Hermetic Cerdip, and Surface Mount (SOIC) packages.
Yes, due to its picoampere input bias currents, it can be used with much higher source impedances while providing DC precision.
