(6) Shorts between pins and misinstallation

When mounting the LSI on a board, pay adequate attention to orientation and placement discrepancies of the

LSI. If it is misinstalled and the power is turned on, the LSI may be damaged. It also may be damaged if it

is shorted by a foreign substance coming between pins of the LSI or between a pin and a power supply or a

pin and a GND.

(7) Operation in strong magnetic fields

Adequately evaluate use in a strong magnetic field, since there is a possibility of malfunction.

(8) The 13 Pin is the reference output terminal, which outputs 1/2 Vcc. Determine the bypass condenser value

in accordance with the desired characteristics. In addition, as the value may oscillate within the 500pF- 1

F,

make sure to set the bypass condenser value of more than 10

F for alternate grounding. Further, as 12 pin is

located in the reference circuit, make sure to use bypass condenser for ac grounding for reference output.

(9) This IC can be stably used in the low grain range (0-2dB). It may oscillate at the capacity load of more than

200pF. [the phase margin 10°Typ.（Ta=85℃, 0dB point）for capacity 200pF] Therefore, caution is required

for using capacity load.

In addition, for using 0db buffer, inserting bias resister of kΩ to minus input will enable stable use against

the capacity load.
