Description

The MAX44291/MAX44292/MAX44294 are single/dual/quad low-noise, precision operational amplifiers. The low offset and low noise specifications and high supply range make the MAX44291/MAX44292/MAX44294 ideal for sensor interfaces, loop-powered systems, and various types of medical and data acquisition instruments.The MAX44291/MAX44292/MAX44294 operate with a wide supply voltage range from a 4.5V to 36V single supply or dual ±2.25V to ±18V supplies, and consume only 1.2mA/channel (typ). The MAX44291 features a shutdown input that reduces the supply current to 1µA/channel (typ) when in shutdown mode.The rail-to-rail output swing maximizes the dynamic range when driving high-resolution ADCs even with low supply voltage. These devices achieve 10MHz of gain-bandwidth product.The MAX44291/MAX44292/MAX44294 are available in an 8-pin µMAX® (single), 8-pin SO (dual), and 14-pin SO (quad) packages and are specified over the -40°C to +125°C automotive temperature range.ApplicationsInstrumentationPortable Logic ControllersSensor InterfacesTest and Measurement Systems
