High-Output-Drive, Precision, Low-Power, SingleSupply, Rail-to-Rail I/O Op Amps with Shutdown
General Description
The MAX4165MAX4169 family of operational amplifiers combines excellent DC accuracy with high output current drive, single-supply operation, and Rail-to-Rail® inputs and outputs. These devices operate from a sing l e +2.7V to +6.5V supply, or from dual ±1.35V to ± 3. 2 5 V supplies. They typically draw 1.2mA supply current, and are guaranteed to deliver 80mA output current. The MAX4166/MAX4168 have a shutdown mode that r e d u c e s supply current to 38µA per amplifier and places the outputs into a high-impedance state. The M A X 4 1 6 5 M A X 4 1 6 9 ' s precision performance comb i n e d with high output current, wide input/output dynamic range, single-supply operation, and low power c o n s u m p t i o n 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.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
