TA8187AFN
TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8187AFN
1.5V Dual FM IF
The TA8187AFN is dual FM IF system IC, developed for
headphone stereo etc.
It is built in dual FM IF systems, dual buffer amplifiers and soft
muting function etc.
Features
· Built−in dual FM IF systems
· Built−in dual buffer amplifiers
· Built−in soft muting function (only dual IF mode)
ATT = 21dB (typ.)
· Low supply current (VCC = 1.2V, Ta = 25°C)
Single IF mode: 2.8mA (typ.)
Dual IF mode: 3.2mA (typ.)
· Built−in mode switch
· Output of buffer amplifier is high−impedance in power off mode.
· Operating supply voltage range (typ.)
VCC (opr) = 0.95~2.2V
Weight: 0.09g (typ.)
