nanoPower Op Amp in Ultra-Tiny WLP and SOT23 Packages

The MAX40007 is a single operational amplifier that provides a maximized ratio of gain bandwidth (GBW) to supply current and is ideal for battery-powered applications such as portable instrumentation, portable medical equipment, and wireless handsets.

This CMOS op amp features an ultra-low supply current of only 700nA (typ), ground-sensing inputs, and rail-to-rail outputs; operating from a single 1.7V to 5.5V supply, allowing the amplifier to be powered by the same 1.8V, 2.5V, or 3.3V nominal supply that powers the microcontroller. The MAX40007 amplifier is unity-gain stable with a 20kHz GBW product.

The ultra-low supply current, low operating voltage, and rail-to-rail output capabilities make this operational amplifier ideal for use in single lithium ion (Li+), two-cell NiCd or alkaline battery systems.

The MAX40007 is available in a 6-pin SOT23 package and an ultra-tiny 6-bump, 1.1mm x 0.76mm wafer-level package (WLP) with a bump pitch of 0.35mm. The amplifier is specified over the -40°C to 125°C operating temperature range.
