MAX40018
EVALUATION KIT AVAILABLE
Dual nanoPower Op Amps
in Tiny WLP and TDFN Packages
General 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.
