TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC The TA2016FN is dual buffer amplifier IC, which is developed for 1.5V Headphone stereo.

FEATURES

@ Output impedance can be changed by mode switch. S$ HUE’ OFF MODE .... High impedance @ Built-in two switching transistors, which are synchronized with mode switch. SSOP10-P-0.65 ©@ Low quiescent current (Vcc = 1.2V, Vin =0, Ta = 25°C) Weight : 0.04g (Typ.) ©@ Operating supply voltage range (Ta = 25°C) Vec (opr) =0.95~2.2V MARKING HHoOng hanod DHAaG Hoooo 961001EBA2 @ TOSHIBA is continually working to improve the quality and the reliability of its products, Nevertheless, semiconductor devices in general can malfunction or fall due to thei inherent electrical sensitivity and, vulnerability to physical stress. itis the responsibilty of the buyer, when utlizing TOSHIBA products, to observe standards of safety, and to avoid situations in which a malfunction or failure of a TOSHIBA product could cause loss of human life, bodily injury or damage to property In developing. your, designs, please ensure that TOSHIBA. products are, used within specified Operating ranges as set forth in the most recent products specifications.

IND : OFF MODE G Ol fe) io OFF gH } ¥cc Lan APPLICATION NOTE (1) VREF Vrer circuit should be stabilized, because this IC operate on Vref voltage. (2) Input stage The resistor between input terminal (Pin@, @) and Veer terminal (Pin®) should be 33kQ or less. In case that this resistance is larger than 33k, this IC doesn’t operate normally. Because, voltage drop at this resistor is increased and constant current source of input stage is saturated. (3) MODE SW In case of MID mode, care should be taken to operate normally. There is a possibility that this IC doesn’t operate normally, because switch condition is open.
