• Manufacturer Part Number: TEA1062AN-D16-T
• Description: LOW VOLTAGE TELEPHONE TRANSMISSION CIRCUIT WITH DIALLER INTERFACE
• Manufacturer: UTC [Unisonic Technologies]

TEA1062N/TEA1062AN
curve (a) is valid when the receiving amplifier is not driven or when MUTE =LOW (UTC TEA1062N is HIGH) .curve(b)
is valid when MUTE=HIGH(UTC TEA1062N is LOW) and the receiving amplifier is driven;
Vo(rms)=150mV,RL=150Ω.The supply possibilities can be increased simply by setting the voltage drop over the
circuit VLN to a high value by means of resistor RVA connected between REG and SLPE.
(a) Magnetic or dynamic microphone. The resistor marked(1) may be connected to decrease the terminating
impedance.
(b) Electret microphone.
(c) Piezoelectric microphone.
