TA2016FN

TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA2016FN 1.5V Buffer Amplifier TA2016FN The TA2016FN is dual buffer amplifier IC, which is developed for 1.5V headphone stereo. Features · Output impedance can be changed by mode switch. H mode ...... 230Ω (typ.) MID mode .... 750Ω (typ.) OFF mode .... high impedance · Built−in two switching transistors, which are synchronized with mode switch. · Low quiescent current (VCC = 1.2V, Vin = 0, Ta = 25°C) H mode ...... ICCQ1 = 2mA (typ.) MID mode .... ICCQ2 = 1mA (typ.) OFF mode .... ICCQ3 = 0.8mA (typ.) · Operating supply voltage range (Ta = 25°C) VCC (opr) = 0.95~2.2V Marking Weight: 0.04g (typ.) 1 2002-10-30 Block Diagram TA2016FN Operation Mode Characteristic Mode SW H MID OFF Impedance [Ω] (Typ.) 230 750 High impedance SW Tr OFF ON ON Terminal Explanation Terminal Voltage: Typical Terminal Voltage with Test Circuit at no Signal.
