low input bias current of a BiFET amplifier and offers a significantly lower IB drift over temperature. It uses superbeta bipolar
input transistors to achieve picoampere input bias current levels
(similar to FET input amplifiers at room temperature), while its
IB typically increases only by 5× at 125°C (unlike a BiFET amp,
for which IB doubles every 10°C, resulting in a 1000× increase at
125°C). In addition, the AD704 achieves 150 μV offset voltage and
the low noise characteristics of a precision bipolar input op amp. 14 +IN AD704 Figure 2. 16-Lead SOIC (R) Package 3 +IN1 4 15 –IN 4 NC 8 (Not to Scale) 9 NC Figure 1. 14-Lead Plastic DIP (N) GENERAL DESCRIPTION 18 +IN4 17 NC 16 –VS 15 NC 14 +IN3 NC = NO CONNECT Figure 3. 20-Terminal LCC
