The MAX4165MAX4169 family of operational ampli- fiers combines excellent DC accuracy with high output current drive, single-supply operation, and Rail-to-Rail®inputs and outputs. These devices operate from a sin- gle +2.7V to +6.5V supply, or from dual ±1.35V to ±3.25V supplies. They typically draw 1.2mA supply current, and are guaranteed to deliver 80mA output current.
The MAX4166/MAX4168 have a shutdown mode that reduces supply current to 38µA per amplifier and places the outputs into a high-impedance state. The MAX4165MAX4169's precision performance com- bined with high output current, wide input/output dynamic range, single-supply operation, and low power consumption makes them ideal for portable audio applications and other low-voltage, battery-powered systems. The MAX4165 is available in the space-saving 5-pin SOT23 package.
