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
