The single MAX9910/MAX9911 and dual MAX9912/MAX9913 operational amplifiers (op amps) feature a maximized ratio of gain bandwidth (GBW) to supply current and are ideal for battery-powered applications such as portable instrumentation, portable medical equipment, and wireless handsets. These CMOS op amps feature an ultra-low input-bias current of 1pA, rail-to-rail inputs and outputs, low supply current of 4µA, and operate from a single 1.8V to 5.5V supply. For additional power conservation, the MAX9911/MAX9913 feature a low-power shutdown mode that reduces supply current to 1nA, and puts the amplifiers' outputs in a high-impedance state. These devices are unity-gain stable with a 200kHz GBW product. The MAX9910 is available in a 5-pin SC70 package. The MAX9911 is available in tiny 6-bump WLP and a 6-pin SC70 packages. The MAX9912 is available in an 8-pin SOT23 package, and the MAX9913 is available in a 10-pin µMAX® package. All devices are specified over the -40°C to +85°C extended operating temperature range.
