MAX4483：Single/Dual/Quad, Low-Cost, Single-Supply, Rail-to-Rail Op Amps with Shutdown

The MAX4480–MAX4483 low-cost, general-purpose op amps offer rail-to-rail outputs, draw only 50µA of quiescent current, and operate from a single +2.5V to +5.5V supply. For additional power conservation, the MAX4481 offers a low-power shutdown mode that reduces supply current to 0.5µA (max) and puts the amplifier’s output in a high-impedance state. These devices are unity-gain stable with capacitive loads up to 400pF. The MAX4480–MAX4483 are specified to +125°C, making them suitable for use in a variety of harsh environments. The MAX4480 is a single amplifier offered in a tiny 5-pin SC70 package. The MAX4481 is a single amplifier with a low-power shutdown mode that reduces supply current to < 0.5µA and comes in a 6-pin SC70 package. The MAX4482 is a dual amplifier and comes in the space-saving 8-pin SOT23 or μMAX® package. The MAX4483 is a quad amplifier and comes in a 14-pin TSSOP package. All devices are specified for operation across the -40°C to +125°C automotive temperature range.
