Maxim Integrated has introduced the MAX40007, a single operational amplifier that provides an optimized gain bandwidth (GBW) to supply current ratio, specially designed for battery-powered systems. The tiny device features an ultra-low supply current of only 700 nA, rail-to-rail output, a stable unity-gain and a 20 kHz GBW product.

It is offered with a broad operating temperature range and in a six-pin SOT23 package, and an ultra-tiny six-bump, 1.1 mm by 0.76 mm wafer-level package (WLP) with a bump pitch of 0.35 mm.
Ideal applications for this device include wearables, mobile phones, portable instrumentation, portable medical equipment and wireless handsets.
Precision specifications for buffer/filter/gain stages:
- Low 300μV input offset voltage
- Rail-to-rail output voltage
- 20kHz BW
- Low 40pA input bias current
- Unity-gain stable
- -40° to 125° C temperature range
