TI’s customers are responsible for determining suitability of components for their purposes. Customers should validateandtesttheirdesignimplementationtoconfirmsystemfunctionality. 9.1 Application Information The LF347 has four independent amplifiers that have very low input bias current which allow using higher resistance resistors in the feedback network. The upper input common mode range typically goes to the positive supply rail. The lower common mode range does not include the negative supply rail; it must be at least 4-V greater.Outputresistanceis200 Ω toprotectthedevicefromaccidentalshorts. 9.2 Typical Application Atypicalapplicationforanoperationalamplifierisaninvertingamplifier.Thisamplifiertakesapositivevoltageon the input, and makes it a negative voltage of the same magnitude. In the same manner, it also makes negative voltagespositive. RF Vsup+ RI V OUT + V IN Vsup- Figure6. InvertingAmplifier 9.2.1 DesignRequirements The supply voltage must be chosen such that it is larger than the input voltage range and output range. For instance, this application scales a signal of ±0.5 V to ±1.8 V. Setting the supply at ±12 V is sufficient to accommodatethisapplication. 9.2.2 DetailedDesignProcedure Determinethegainrequiredbytheinvertingamplifier: VOUT A = V VIN (1) 1.8 A = =-3.6 V -0.5 (2) Whenthedesiredgainisdetermined,chooseavalueforRIorRF.ChoosingavalueinthekΩ rangeisdesirable because the amplifier circuit uses currents in the milliamp range.

Place the 0.1-μF bypass capacitors close to the power-supply pins to reduce errors coupling in from noisy or high-impedance power supplies. For more detailed information on bypass capacitor placement, see Layout Example. 11 Layout 11.1 Layout Guidelines Forbestoperationalperformanceofthedevice,usegoodPCBlayoutpractices,including: • Noise can propagate into analog circuitry through the power pins of the circuit as a whole, as well as the operational amplifier. Bypass capacitors are used to reduce the coupled noise by providing low impedance powersourceslocaltotheanalogcircuitry. – Connect low-ESR, 0.1-μF ceramic bypass capacitors between each supply pin and ground, placed as close to the device as possible. A single bypass capacitor from V+ to ground is applicable for single supplyapplications. • Separate grounding for analog and digital portions of circuitry is one of the simplest and most-effective methods of noise suppression. One or more layers on multilayer PCBs are usually devoted to ground planes. A ground plane helps distribute heat and reduces EMI noise pickup. Make sure to physically separate digital and analog grounds, paying attention to the flow of the ground current. For more detailed information, see the chapterextract,CircuitBoardLayoutTechniques (SLOA089). • To reduce parasitic coupling, run the input traces as far away from the supply or output traces as possible. If it is not possible to keep them separate, it is much better to cross the sensitive trace perpendicular as opposedtoinparallelwiththenoisytrace. • Place the external components as close to the device as possible.
