AD706 is a dual-channel 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 AD706 is a dual, low power, bipolar op amp that combines the low input bias current of a BiFET amplifier with significantly lower input offset voltage drift over temperature. It utilizes superbeta bipolar input transistors to achieve picoampere input bias current levels while maintaining microvolt offset voltage and low noise characteristics typical of precision bipolar amplifiers.
| Input Offset Voltage (Max) | 50 µV |
|---|---|
| Offset Drift (Max) | 0.6 pV/°C |
| Input Bias Current (Max) | 110 pA |
| Voltage Noise (0.1 Hz to 10 Hz) | 0.5 pV p-p |
| Supply Current (Typical) | 750 pA |
| Unity Gain Crossover Frequency | 0.8 MHz |
| Slew Rate | 0.15 V/µs |
The AD706 is offered in five performance grades, including commercial (AD706J/K) and industrial (AD706A/B) temperature ranges.
The device is available in 8-Lead Plastic Mini-DIP, Hermetic Cerdip, and Surface Mount (SOIC) packages.
No, because it has only 1/20 the input bias current of an OPO7, it does not require the commonly used “balancing” resistor.
