TA7540F

The TA7540F is a programmable monolithic precision micro-power operational amplifier that can be used either in signal or dual supply operation.A signal external bias current setting resistor programs the input bias current,input offset current,quiescent power consumption,slew rate,and the gain-bandwidth product.Features of the TA7540F are:(1)very low power consumption; (2)programmbale supply current:25~85A(Typ.); (3)wide power supply range:single supply 3~36V;dual supplies±1.5~±18V; (4)input common-mode voltage range includes groud; (5)low input offset voltage:1mV(Typ.); (6)low input offset current:0.5nA(Typ.); (7)no frequency compensation required; (8)programmable electrical characteristics; (9)offset voltage nulling capability.

The absolute maximum ratings of the TA7540F can be summarized as:(1)supply voltage:±18V or 36V; (2)differential input voltage:±36V; (3)input voltage:-0.3~36 V (4)power dissipation:240mW; (5)operating temperature:-40~85; (6)storage temperature:-55~125.

The electrical characteristics(Ta=25) of the TA7540F can be summarized as:(1)input offset voltage:1mV TYP. 5mV MAX.; (2)input offset current:0.5nA TYP.  30nA MAX.; (3)input bias current:6nA MIN. 100nA MAX.; (4)common mode input voltage:VEE MIN. VCC-1.5 MAX.If you want to know more information such as the electrical characteristics ,please download the datasheet in www.seekdatasheet.com .
