The document introduces the characteristics of the AD704 product, including high precision, low offset voltage, low offset voltage drift, low input bias current, low noise and low power consumption.
The AD704 is a quad, low power bipolar op amp designed to offer the low input bias current of a BiFET amplifier combined with significantly lower input offset voltage drift over temperature. It utilizes Super-beta bipolar input transistors to achieve picoampere input bias current levels while maintaining precision bipolar characteristics.
| Input Offset Voltage (Max) | 75 µV |
|---|---|
| Input Bias Current (Max) | 150 pA |
| Supply Current per Amplifier (Max) | 600 µA |
| Operating Temperature Range (AD704J/K) | 0°C to +70°C |
| Operating Temperature Range (AD704T) | -55°C to +125°C |
| Unity Gain Crossover Frequency | 0.8 MHz |
The AD704 is suitable for industrial/process controls, weighing scales, ECG/EKG instrumentation, low frequency active filters, and precision instrumentation.
No, because it has only 1/20 the input bias current of an AD OP07, it does not require the commonly used 'balancing' resistor.
Yes, it is available in Tape and Reel in accordance with EIA-481A Standard.
