MAX44265 19-5709 Rev 0 12/10 Rail-to-Rail, 200kHz Op Amp with Shutdown in a Tiny, 6-Bump WLP General Description Features The MAX44265 op amp features a maximized ratio of 200kHz GBW gain bandwidth (GBW) to supply current and is ideal for Ultra-Low 4A Supply Current battery-powered applications such as handsets, tablets, notebooks, and portable medical equipment. Single 1.8V to 5.5V Supply Voltage Range This CMOS op amp features an ultra-low input-bias cur- Ultra-Low 1pA Input Bias Current rent of 1pA, rail-to- rail input and output, low supply cur- rent of 4A, and operates from a single 1.8V to 5.5V Rail-to-Rail Input and Output Voltage Ranges supply. For additional power conservation, the IC also features a low-power shutdown mode that reduces sup- Low 200V Input Offset Voltage ply current to 1nA and puts the amplifiers outputs in a Low 0.001A Shutdown Current high-impedance state. This device is unity-gain stable with a 200kHz GBW product. High-Impedance Output During Shutdown It is available in a space-saving, 0.9mm x 1.3mm, Unity-Gain Stable 6-bump WLP package and is specified over the -40C Available in a Tiny, 0.9mm x 1.3mm, 6-Bump WLP to +85C extended operating temperature range.
