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.
The MAX9914–MAX9915 (single) and MAX9916–MAX9917 (dual) operational amplifiers are CMOS devices optimized for battery‑powered applications. They operate from a single 1.8 V to 5.5 V supply, provide rail‑to‑rail input and output ranges, and consume only 20 µA typical supply current.
A low‑power shutdown input reduces the supply current to about 1 nA and places the outputs in a high‑impedance state. The devices are unity‑gain stable with a 1 MHz gain‑bandwidth product and feature an ultra‑low 1 pA input bias current, making them suitable for portable medical equipment, test instruments, and wireless handsets.
