MAX4245/MAX4246/ Ultra-Small, Rail-to-Rail I/O with Disable, MAX4247 Single-/Dual-Supply, Low-Power Op Amps General Description Features The MAX4245/MAX4246/MAX4247 family of low-cost op Rail-to-Rail Input and Output Voltage Swing amps offer rail-to-rail inputs and outputs, draw only 320A 50nA (max) Shutdown Mode (MAX4245/MAX4247) of quiescent current, and operate from a single +2.5V 320A (typ) Quiescent Current Per Amplifier to +5.5V supply. For additional power conservation, the MAX4245/MAX4247 offer a low-power shutdown mode Single +2.5V to +5.5V Supply Voltage Range that reduces supply current to 50nA, and puts the ampli- 110dB Open-Loop Gain with 2k Load fiers outputs in a high-impedance state. These devices 0.01% THD with 100k Load are unity-gain stable with a 1MHz gain-bandwidth prod Unity-Gain Stable up to C = 470pF uct driving capacitive loads up to 470pF. LOAD No Phase Inversion for Overdriven Inputs The MAX4245/MAX4246/MAX4247 family is specified from -40C to +125C, making them suitable for use in Available in Space-Saving Packages a variety of harsh environments. The MAX4245 single 6-Pin SC70 or 6-Pin SOT23 (MAX4245) amplifier is available in ultra-small 6-pin SC70 and space- 8-Pin SOT23/SO or 8-Pin MAX (MAX4246) saving 6-pin SOT23 packages. The MAX4246 dual 10-Pin MAX (MAX4247) amplifier is available in 8-pin SOT23, SO, and MAX packages. The MAX4247 dual amplifier comes in a tiny Ordering Information 10-pin MAX package.
