... For additional power conserva- tion, the MAX4245/MAX4247 offer a low-power shutdown mode that reduces supply current to 50nA, and puts the amplifiers’ outputs in a high-impedance state. These devices are unity-gain stable with a 1MHz gain-band- width product driving capacitive loads up to 470pF ...

... Reducing input DD capacitance or placing a small capacitor across the feedback resistor improves response in this case. The MAX4245/MAX4246/MAX4247 family’s inputs are protected from large differential input voltages by inter- nal 5.3kΩ series resistors and back-to-back triple-diode stacks across the inputs (Figure 2). For differential- input voltages much less than 2 ...

... The MAX4245/MAX4246/MAX4247 output typically set- tles within 4µs after power-up. Figure 4 shows the out- put voltage on power-up and power-down. The MAX4245/MAX4247 feature a low-power shutdown mode. When SHDN_ is pulled low, the supply current drops to 50nA per amplifier, the amplifier is disabled, and the output enters a high-impedance state. Pulling ...

... R divider with the R . LOAD Power-Supply Bypassing and Layout The MAX4245/MAX4246/MAX4247 family operates from either a single +2.5V to +5.5V supply or dual ±1.25V to ±2.75V supplies. For single-supply operation, bypass the power supply with a 100nF capacitor to V case GND). For dual-supply operation, both the V ...
