... All devices provide a gain-bandwidth product of 750kHz. The MAX4208 provides an adjustable gain with two external resistors or unity gain with FB connected to OUT. The MAX4209 is available with a fixed gain of 100V/V with ±0.03% (typ) accuracy. Both devices include a reference input (REF) to level-shift the output, allowing for bipolar signals in single-supply applications ...

... Output Reference Level. REF sets the OUT voltage for zero differential input. The internal buffer 5 REF sets the voltage at REF when the voltage at REFIN/MODE is between V Feedback Input. Connect FB to the center tap of an external resistive divider from OUT to REF to set the gain for the MAX4208. MAX4209 FB is internally connected to gain-setting resistors. Connect optional capacitor ...

... These two currents are sub- tracted and the result is fed to a loop amplifier with suffi- cient gain to minimize errors (Figures 1 and 2). The MAX4209 has a factory-trimmed gain of 100V/V. The MAX4208 has an adjustable gain, set with an external pair of resistors between OUT, FB, and REF (Figure 1). ...
