TA8125S

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) Block Diagram TA8125S 1 2002-10-30 Maximum Ratings (Ta = 25°C) TA8125S Characteristic Symbol Rating Unit Supply voltage Power dissipation Operating temperature Storage temperature (Note) VCC PD Topr Tstg 16 700 -30~80 -55~150 V mW °C °C (Note) Derated above Ta = 25°C in the proportion of 5.6mW / °C.
