Fig.9 Equivalent AC impedance between LN and VEE.
The equivalent impedance connected between LN and
VEE is illustrated in Fig.9.
Where:
• LEQ = REQ × CREG × RSLPE
• REQ = 40 kΩ
• ZSET = 1⁄10ZSIMP.
Remark: a resistor R (REG-VEE) connected between REG
and VEE (to lower the regulated voltage) changes REQ into
REQ // R (REG-VEE), whereas a resistor RREG-SLPE
connected between REG and SLPE (to increase the
regulated voltage) has no effect on REQ.
Dynamic limiter of the microphone channel: pin DLS
The dynamic limiter in the microphone channel of the
TEA1096/TEA1096A prevents clipping of the microphone
signal, and limits the transmitted signal on LN to a
maximum value of typically 3.65 V (4.4 dBm).
Clipping on the microphone channel is prevented by
rapidly reducing the gain when the output stage starts to
saturate. The time in which the gain reduction is effected
(clipping attack time) is approximately a few milliseconds.
The microphone channel stays in the reduced gain mode
until the peaks of the signal no longer cause saturation.
The gain of the microphone channel then returns to its
normal value within the clipping release time.
Both attack and release time are proportional to the value
of the capacitor CDLS. The THD (Total Harmonic
Distortion) of the microphone amplifier in the reduced gain
mode stays below 2% up to 10 dB of input voltage
overdrive [provided that VMICP, VMICM is below 10 mV
(RMS)].
The dynamic limiter of the TEA1096/TEA1096A also
provides a microphone mute (secret function) when pin
DLS is short-circuited to VEE. The microphone gain is then
80 dB lower. The release time after a microphone mute is
approximately 10 ms.
