Set impedance

In the audio frequency range, the dynamic impedance is mainly determined by the RCC resistor. The

equivalent impedance of the circuit is illustrated in Fig.5.

Microphone amplifier (pins MIC+ and MIC-)

The UTC TEA1110A has symmetrical microphone inputs. The input impedance between pins MIC+ and MIC-

is 64 kΩ ( 2 × 32 kΩ). Automatic gain control is provided on this amplifier for line loss compensation.

Receiving amplifier (pins IR, GAR and QR)

The receiving amplifier has one input (IR) and one output (QR). The input impedance between pin IR and pin

VEE is 20 kΩ. The voltage gain from pin IR to pin QR can be decreased by connecting an external resistor RGAR

between pins GAR and QR; the adjustment range is 14 dB. Two external capacitors CGAR

(connected between GAR and QR) and CGARS (connected between GAR and VEE) ensure stability. The CGAR

capacitor provides a first-order low-pass filter. The cut-off frequency corresponds to the time constant CGAR ×(RGARint

// RGAR). RGARint is the internal resistor (connected between pins GAR and QR) which sets the gain with a typical

value of 125 kW. The condition CGARS = 10 ×CGAR must be fulfilled to ensure stability.

The output voltage of the receiving amplifier is specified for continuous wave drive. The maximum output

swing depends on the DC line voltage, the RCC resistor, the ICC current consumption of the circuit, the IP current

consumption of the peripheral circuits and the load impedance.
