Ultra-Low Power Op-Amp Devices

Ultra-Low Power Op-Amp Devices

The MAX40018 dual operational amplifiers, from Maxim Integrated, consume only 400nA supply current per channel. This makes these devices, based on the company’s nanoPower technology, highly suitable for portable battery-powered and wearable applications. Each operates from a single 1.7V to 5.5V supply and is powered by the same 1.8V, 2.5V, or 3.3V nominal supply as the system microcontroller. These op-amps feature rail-to-rail outputs and are unity-gain stable with a 9kHz gain bandwidth product. They are housed in 1.63mm x 0.91mm x 0.5mm WLP-8 packages with a 0.4mm pump pitch. An operational temperature range of -40°C to +125°C is supported.
