TA2047N

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 · Built−in CR for LPFs and output (differential) amplifiers for the left and right channel. · Built−in audio SW and possible to FM signal input dynamic range up. (VCC = 9V) · It is possible to apply an analog de−emphasis circuit. · 2Vrms output. (VCC = 9V) · 6dB up SW. (9V operation) · Built−in analog mute circuit. · 9V power supply operation. (5V, 12V possible) Weight SDIP24−P−300−1.78 : 1.22g (typ.)
