TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA2025P,TA2025F
TA2025P / F
Low Noise Preamplifier For Autoreverse Car Stereo
The TA2025P, TA2025F contains dual amplifier, forward, reverse
control switches and metal, normal tape equalizer control
switches.
Feature
· High voltage gain
: GVO = 100dB (typ.) (VCC = 9V, f = 1kHz)
· No input coupling capacitor
· Low noise (equivalent noise voltage)
: VNI = 0.6µVrms (typ.) (VCC = 9V, Rg = 620
BW = 20Hz~20kHz, NAB EQ)
· Low distortion: THD = 0.01% (typ.)
· Operating supply voltage range: VCC (opr.) = 6~16V

(2) The recommended forward, reverse
select circuit is shown in Fig.2.
TA2025P / F
(3) I3 (in Fig.1)
I3 = 12µA (max., Ta = 25°C)
2. Equalizer control switch
Pin(15) is coupled to the base of Q2 (PNP-Tr) as shown in Fig.3.
The emitter potential of Q2 is 3.9V (DC).
Threshold voltage (pin(15)) = 2.8V
Metal
Normal
3.2~16V
0~2.4V
3. C2 / C3 / C4 / C5
Capacitor C2~C5 may be required for preventing a instability caused
by the pattern layout or interference of external high frequency signal.
