Overview
UNISONIC TECHNOLOGIES CO.
, LTD TEA1110A LINEAR INTEGRATED CIRCUIT LOW VOLTAGE VERSATILE TELEPHONE TRANSMISSION CIRCUIT WITH DIALLER INTERFACE SOP-14  DESCRIPTION The UTC TEA1110A is a versatile telephone transmission circuit providing full speech and line interface functions in electronic telephone sets.
This device works at a line voltage which can be as low as 1.
6V DC (with reduced performance) to enable parallel connection of telephone sets.
It also realizes electronic switching between speeches and dialling.
The UTC TEA1110A is ideal for applications, such as line powered telephone sets, cordless telephones, and fax machines, answering machines.
 FEATURES * Low DC line voltage; operates down to 1.
6V (excluding voltage drop over external polarity guard) * Voltage regulator with adjustable DC voltage * Provides a supply for external circuits * Symmetrical high impedance inputs (64kΩ) for dynamic, magnetic or piezo-electric microphones * Asymmetrical high impedance input (32...
