The single MAX9914/MAX9915 and dual MAX9916/MAX9917 operational amplifiers feature maximized ratio of gain bandwidth 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 1pA input bias current, rail-to-rail inputs and outputs, low 20µA supply current, and operate from a single 1.8V to 5.5V supply. For additional power conservation, the MAX9915/MAX9917 feature a low-power shutdown mode that reduces supply current to 1nA, and puts the amplifier outputs in a high-impedance state. These devices are unity-gain stable with a 1MHz gain-bandwidth product.The MAX9914 and MAX9915 are available in 5-pin and 6-pin SC70 packages, respectively. The MAX9916 is available in an 8-pin SOT23 package, and the MAX9917 in a 10-pin µMAX®package. All devices are specified over the -40°C to +85°C extended operating temperature range.ApplicationsCellular HandsetsCordless PhonesData-Acquisition EquipmentDigital Cameras (DIGICAMs)Glucose MetersGPS SolutionsIP CameraLaptopsMP3 and Portable Media PlayersPortable Medical DevicesPortable Test EquipmentRF Tags
