The MAX40007ANT+T is a single-channel CMOS op-amp from the nanoPower series. It draws 700 nA supply current with a 15 kHz gain-bandwidth product and rail-to-rail output.
The headline 700 nA supply current is the reason to pick this part. In a battery-powered design that spends most of its life in a low-duty-cycle sense-and-sleep loop, that quiescent draw is comparable to the leakage of a few ceramic capacitors. It lets you leave the op-amp powered continuously without draining a coin cell in weeks. The 15 kHz gain-bandwidth is enough for DC-accurate measurements — thermocouple amplifiers, photodiode front-ends, battery voltage dividers — but not for audio or high-speed control loops. If you need more bandwidth, you will trade supply current; this part optimises for the battery side of that trade.
Package and handling — the 6-WLP reality
The 6-WLP (1.08x0.73 mm) package is a wafer-level chip-scale package with solder bumps directly on the die. The package is surface mount only.
It is RoHS3 compliant.
