MAX9914MAX9917 1MHz, 20A, Rail-to-Rail I/O Op Amps with Shutdown General Description Features The single MAX9914/MAX9915 and dual MAX9916/ High 1MHz GBW MAX9917 operational amplifiers feature maximized ratio Ultra-Low 20A Supply Current of gain bandwidth to supply current and are ideal for Single 1.8V to 5.5V Supply Voltage Range battery-powered applications such as portable instru- mentation, portable medical equipment, and wireless Ultra-Low 1pA Input Bias Current handsets. These CMOS op amps feature an ultra-low Rail-to-Rail Input and Output Voltage Ranges 1pA input bias current, rail-to-rail inputs and outputs, Low 200V Input Offset Voltage low 20A supply current, and operate from a single 1.8V Low 0.001A Shutdown Current to 5.5V supply. For additional power conservation, the MAX9915/MAX9917 feature a low-power shutdown mode High-Impedance Output During Shutdown that reduces supply current to 1nA, and puts the amplifier (MAX9915/MAX9917) outputs in a high-impedance state. These devices are Unity-Gain Stable unity-gain stable with a 1MHz gain-bandwidth product. Available in Tiny SC70, SOT23, and MAX Packages The MAX9914 and MAX9915 are available in 5-pin and 6-pin SC70 packages, respectively. The MAX9916 is avail- Ordering Information able in an 8-pin SOT23 package, and the MAX9917 in a 10-pin MAX package. All devices are specified over the PIN- TOP PART TEMP RANGE -40C to +85C extended operating temperature range.
