MAX9914–MAX9917
1MHz, 20μA, Rail-to-Rail
I/O Op Amps with Shutdown
General Description
Features
● High 1MHz GBW
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 instru-
mentation, 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.
● Ultra-Low 20μA Supply Current
● Single 1.8V to 5.5V Supply Voltage Range
● Ultra-Low 1pA Input Bias Current
● Rail-to-Rail Input and Output Voltage Ranges
● Low ±200μV Input Offset Voltage
● Low 0.001μA Shutdown Current
● High-Impedance Output During Shutdown

● Available in Tiny SC70, SOT23, and μMAX Packages
The MAX9914 and MAX9915 are available in 5-pin and
6-pin SC70 packages, respectively. The MAX9916 is avail-
able in an 8-pin SOT23 package, and the MAX9917 in a
