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.
