AD704AR-16-REEL: 运算放大器SOIC-16封装
The AD704 is a quad, 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. It utilizes Super-beta bipolar input transistors to achieve picoampere input bias current levels (similar to FET input amplifiers at room temperature), while its IB typically only increases by 5× at +125°C (unlike a BiFET amp, for which IB doubles every 10°C resulting in a 1000× increase at +125°C). Furthermore the AD704 achieves 75 µV offset voltage and low noise characteristics of a precision bipolar input op amp.
Since it has only 1/20 the input bias current of an AD OP07, the AD704 does not require the commonly used "balancing" resistor. Furthermore, the current noise is 1/5 that of the AD OP07 which makes the AD704 usable with much higher source impedances. At 1/6 the supply current (per amplifier) of the AD OP07, the AD704 is better suited for today's higher density circuit boards and battery powered applications.
The AD704 is an excellent choice for use in low frequency active filters in 12- and 14-bit data acquisition systems, in precision instrumentation, and as a high quality integrator. The AD704 is internally compensated for unity gain and is available in five performance grades. The AD704J and AD704K are rated over the commercial temperature range of 0°C to +70°C. The AD704A and AD704B are rated over the industrial temperature of -40°C to +85°C. The AD704T is rated over the military temperature range of -55°C to +125°C and is available processed to MIL-STD-883B, Rev. C.
