Proper care in changing voltage gain
An external resistor can be connected in series with the feedback capacitor at pin 3 to reduce the voltage gain.
(See RNF-VG characteristic.)
Proper cares in using IC
1. Maximum ratings
If the IC is used in the vicinity of the maximum ratings, even a slight variation in conditions may cause the
maximum ratings to be exceeded, thereby leading to breakdown. Allow an ample margin of variation for supply
voltage, etc. and use the IC in the range where the maximum ratings are not exceeded.
2. Pin-to-Pin short
If power is applied when the space between pins is shorted, breakdown or deterioration may occur. When mounting
the IC on the board or applying power, make sure that the space between pins is not shorted with solder, etc.
3. Radio applications
For use in radio applications, keep a good distance between IC and bar antenna.
4. Printed circuit pattern
When designing the printed circuit pattern, make the power supply, output, and ground lines thicker and shorter and
determine the pattern and parts placement so that no feedback loop is formed between input and output. Place power
capacitor C6, oscillation blocking capacitor C3 as close to the IC pin as possible to prevent oscillation from
occurring. See the sample printed circuit pattern.
