Technical content

The MAX40006 op amp features a maximized ratio of gain bandwidth (GBW) to supply current and is ideal for battery- powered applications such as handsets, tablets, notebooks, and portable medical equipment. This CMOS op amp features an ultra-low input-bias current of 1pA, rail-to- rail input and output, low supply current of 4.5μA, and operates from a single 1.7V to 5.5V supply. For additional power conservation, the IC also features a low-power shutdown mode that reduces supply current to 0.1µA and puts the amplifier’s outputs in a high-impedance state. This device is unity-gain stable with a 300kHz GBW product. The MAX40006 is available in a space-saving, 0.73mm x 1.07mm, 6-bump wafer-level package (WLP), as well as a 6-pin SOT-23 package. The device is specified over the -40°C to +125°C automotive operating temperature range.
