Description

The MAX40018 is a dual operational amplifier that consumes only 400nA supply current (per channel). At such low power consumption, the device is ideal for battery-powered applications such as portable medical equipment, portable instruments and wireless handsets.

The MAX40018 operates from a single 1.7V to 5.5V supply, allowing the device to be powered by the same 1.8V, 2.5V, or 3.3V nominal supply that powers the microcontroller. The MAX40018 features rail-to-rail outputs and is unity-gain stable with a 9kHz gain bandwidth product (GBP).

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

The MAX40018 is available in a tiny, 8-bump, 1.63mm x 0.91mm wafer-level package (WLP), with a bump pitch of 0.4mm, as well as in an 8-pin 3mm x 3mm TDFN package. The device is specified over the -40°C to +125°C, automotive temperature range.
