Description
TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8125S
Dual Pre−Amplifier
The TA8125S is dual output preamplifier designed for car or home use.
Features
· High open loop voltage gain
: GVO = 100dB (typ.) at f = 1kHz
· Excellent channel separation and high ripple rejection
: CHsep = 65dB (typ.) (f = 10kHz, Rg = 2.2kΩ, VOUT = 0.775Vrms (0dBm))
: R.R. = 50dB (typ.) (fripple = 100Hz, Rg = 2.2kΩ, VOUT = 0.775Vrms (0dBm))
Weight: 0.92g (typ.)
· Low noise
: VNI = 1.0µVrms (typ.) at Rg = 2.2kΩ, BW = 20Hz~20kHz, NAB EQ
· Wide operating supply voltage range: VCC (opr.) = 6~16V (Ta = 25°C)
