Application Circuit
NOTES:

sets the 2-wire to 4-wire gain. R
5
= 150k
then A

= 0dB. R
5
= 75k
then A
2-4
= -6.0dB.
7. Secondary protection diode bridge recommended is a 2A, 200V type.
8. All grounds (AG, BG, and DG) must be applied before V
CC
or V
BAT
. Failure to do so may result in premature failure of the part. If a user wishes
to run separate grounds off a line card, the AG must be applied first.
9. Application shows Ring Injected Ringing, Balanced or Tip injected configuration may be used.
