Product specification
TEA1113
The preferred value for RSLPE is 20 Ω. Changing RSLPE will affect more than the DC characteristics; it also influences the
microphone and DTMF gains, the LED supply current characteristic, the gain control characteristics, the sidetone level
and the maximum output swing on the line.
