Product Specification
Speech and listening-in IC
TEA1096; TEA1096A
The function of the current switch TR1-TR2 is to reduce
distortion of large line signals. Current ISUP is supplied to
VBB via TR1, when VSLPE is higher than VBB + 0.4 V. When
VSLPE is lower, this current is shunted to VEE via TR2. All
excess line current, not used for internal supply is
consumed in the VBB stabilizer or directly shunted to VEE.
To reduce the current consumption during pulse dialling,
the TEA1096/TEA1096A are provided with a power-down
(PD) input. The PD input has a pull-down structure. When
the voltage on PD is HIGH, the current consumption from
VDD capacitor CVDD is 100 µA and from the VBB supply
point 350
µA. The capacitors CVDD (100 µF) and CVBB
(470
µF) are sufficient to power theTEA1096/TEA1096A
during pulse dialling/flash.
VBB voltage adjustment: pin VBA (TEA1096 only)
A resistor connected between pins VBA and VEE can be
used to increase the VBB voltage, whereas a resistor
connected between pins VBA and VBB will decrease the
VBB voltage. When adjusting the VBB voltage to a higher
value, care should be taken that VSLPE is at least 0.4 V
higher than VBB (VBB supply efficiency).
Sending channel: pins MICP, MICM, DTMF, GAS, OSP,
LN, MUTE, DLS and AGC
The TEA1096/TEA1096A has symmetrical microphone
inputs MICP, MICM with an input resistance of 64 k
between MICP and MICM (2
× 32 kΩ). In the speech mode
(MUTE = LOW), the overall gain from MICP-MICM to LN
can be adjusted from 33 dB to 52 dB to suit specific
requirements. The gain is proportional to the value of RGAS
and equals 52 dB with RGAS = 90.9 kΩ and Iline = 20 mA. A
capacitor CGAS connected in parallel with RGAS can be
used to provide a first-order low-pass filter.
Automatic gain control (AGC) is provided for line-loss
compensation as well as dynamic limitation for reduction
of the distortion of the transmitted signal on the line. The
microphone amplifier can be disabled by short-circuiting
pin DLS to VEE (secret function) and can be muted into
DTMF mode by applying a HIGH level on pin MUTE.
The TEA1096/TEA1096A has an asymmetrical DTMF
input with an input resistance of 20 k
Ω. In the DTMF mode,
the overall gain from DTMF to LN is proportional to RGAS,
and is 26.5 dB less than the microphone amplifier gain.
Switch-over from one mode to the other is click-free.
