TA7795F

The TA7795F is is dual preamplifiers ICs,which are designed for low voltage operation(1.5V,3V).It is especially suitable for a stereo headphone cassette player and for that of auto-reverse type.Features of the TA7795F are:(1)swithover between F/R directional mode is possible with only one-make switch; (2)built-in M/N equalizer drivers,switchover between M/N equalizer mode is possible with only one-make switch.Those drivers are applicable to LED driver for F/R display ,too (VLED2.5V).; (3)low noise (equivalent input noise). Vni=1.3Vrms(Typ.) (VCC=1.5V,Rg=2.2k,BPF=20~20kHz); (4)low supply current.ICC=1.6mA(Typ.)(VCC=1.5V,Ta=25); (5)operating supply voltage range.VCC(opr)=0.9~4.5V(Ta=25).

The absolute maximum ratings of the TA7795F can be summarized as:(1)supply voltage:5V; (2)LED supply voltage:6V; (3)LED driver current:5mA; (4)power dissipation:350mW; (5)operating temperature:-25~75; (6)storage temerature:-55~150.

The electrical characteristics(Ta=25) of the TA7795F can be summarized as:(1)supply current:1.6mA TYP. 2.5mA MAX.; (2)reference voltage:1.0V MIN. 1.1V TYP. 1.2V MAX.; (3)open loop voltage gain:60dB MIN. 66dB TYP. ; (4)closed loop voltage gain:31dB TYP.If you want to know more information such as the electrical characteristics ,please download the datasheet in www.seekdatasheet.com .
