TA2047N / F
TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TENTATIVE TA2047N,TA2047F
Filter IC For NICAM
The TA2047N, TA2047F is an analog filter IC for NICAM.
Using the TA2047N, TA2047F in combination the TB1212N,
TB1212F (single chip NICAM system), it is possible to construct a
NICAM decoder system with less external parts.
Features
· Builtin CR for LPFs and output (differential) amplifiers for
the left and right channel.
· Builtin audio SW and possible to FM signal input dynamic
range up. (VCC = 9V)
· It is possible to apply an analog deemphasis circuit.
· 2Vrms output. (VCC = 9V)
· 6dB up SW. (9V operation)
· Builtin analog mute circuit.
· 9V power supply operation. (5V, 12V possible)
