... Additionally, input voltage noise density is 8nV/√Hz while operating from a single +4.5V to +8.0V sup- ply or from dual ±2.25V to ±4.0V supplies. These features make the MAX4265–MAX4270 ideal for use in high-perfor- mance communications and signal-processing applica- tions that require low distortion and wide bandwidth. ...

... The input common-mode voltage ranges from (V 1.6V 1.6V), while the output typically swings CC to within 1.1V of the rails. The MAX4265–MAX4270 use proprietary bipolar tech- nology to achieve minimum distortion in low-voltage systems. This feature is typically available only in dual- supply op amps. Several factors can affect the noise and distortion that a device contributes to the input signal ...

... Choosing Resistor Values Unity-Gain Configurations The MAX4265 and MAX4268 are internally compensat- ed for unity gain. When configured for unity gain, they require a small resistor ( series with the feedback F path (Figure 1). This resistor improves AC response by reducing the Q of the tank circuit, which is formed by parasitic feedback inductance and capacitance ...
