TEA1085
FEATURES - Internal supply optimum current split-up - low constant current (adjustable) in transmission IC - nearly all line current available for listening-in adjustable supply voltage - Loudspeaker amplifier dynamic limiter providing low distortion and the highest possible output power SE or BTL drive for loudspeaker volume control by potentiometer and/or logic inputs (e.g. microcontroller drive) fixed gain of 35 d B - Larsen level limiter low sensitivity for own speech due to 3rd-order filter and attack delay adjustable voltage thresholds - Power down input - MUTE input TEA1085/TEA1085A - clickfree switching between listening-in mode and standby mode TEA1085 - toggle function - start-up in standby condition TEA1085A - logic level input ORDERING INFORMATION EXTENDED TYPE NUMBER TEA1085/TEA1085A TEA1085T/TEA1085AT Notes 1.
