*Assumes Z_o = Z_NB = 600Ω, Gain 2 - 4 = -1dB, Gain 4 - 2 = -1dB.
Decoupling capacitors, (1uF, 100V, 20%), can be added to V_DD, V_EE, V_BAT and V_RLY to provide improved
PSRR performance.

PR1 = This device must always be fitted to ensure damage does not occur from inductive loads.For
simple applications, PR1 can be replaced by a single TVS, such as 1.5KE220C, across tip and ring. For
applications requiring lightning and mains cross protection further circuitry will be required and the following
protection devices are suggested: P2353AA, P2353AB (Teccor), THBT20011, THBT20012, THBT200S (SGS-
Thomson), TISP2290, TSSP8290L (T.I.)
