(3) (4) (5) (6) (7) 8.2.2.1 amplifier selection linearity over the input range is key for good dc accuracy. the common-mode input range and output swing limitations determine the linearity. in general, an amplifier with rail-to-rail input and output swing is required. bandwidth is a key concern for this design, so the opa2314-q1 device is selected because its bandwidth is greater than the target of 1 mhz. the bandwidth and power ratio makes this device power efficient and the low offset and drift ensure good accuracy for moderate precision applications. 8.2.2.2 passive component selection because the transfer function of vout ? is heavily reliant on resistors (r 1 , r 2 , r 3 , and r 4 ), use resistors with low tolerances to maximize performance and minimize error. this design uses resistors with resistance values of 49.9 k and tolerances of 0.1%. however, if the noise of the system is a key parameter, smaller resistance values (6 k or lower) can be selected to keep the overall system noise low. this ensures that the noise from the resistors is lower than the amplifier noise. 8.2.3 application curves figure 40. v out+ vs input voltage figure 41. v out ? vs input voltage copyright ? 2011 ? 2015, texas instruments incorporated submit documentation feedback 23 product folder links: opa314 opa2314 opa4314 287 287 cm ref v v 1 v v 2 2 ? ? 1 diff in ref v 2 v v u 287 5() ,1 v v v 2 4 2 ',)) 287 287 ,1 5() 1 3 4 1 r r r v v v v 1 v 1 r r r r u u u ? ? ? ? 1 ? 1 ? 1 out in v v 0.00 0.50 1.00 1.50 2.00 2.50 0.00 0.50 1.00 1.50 2.00 2.50 vout+ (v) input voltage (v) c027 0.00 0.50 1.00 1.50 2.00 2.50 0.00 0.50 1.00 1.50 2.00 2.50 vout- (v) input voltage (v) c027
