Description

The MAX44244/MAX44245/MAX44248 family of parts provide ultra-precision, low-noise, zero-drift single/quad/ dual operational amplifiers featuring very low-power operation with a wide supply range. The devices incorporate a patented auto-zero circuit that constantly measures and compensates the input offset to eliminate drift over time and temperature as well as the effect of 1/f noise. These devices also feature integrated EMI filters to reduce high-frequency signal demodulation on the output. The op amps operate from either a single 2.7V to 36V supply or dual ±1.35V to ±18V supply. The devices are unity-gain stable with a 1MHz gain-bandwidth product and a low 90µA supply current per amplifier.The low offset and noise specifications and high supply range make the devices ideal for sensor interfaces and transmitters.The devices are available in µMAX®, SO, SOT23, and TSSOP packages and are specified over the -40°C to +125°C automotive operating temperature range.Applications4-20mA and 0 to 10V TransmittersPLC Analog I/O ModulesPortable Medical DevicesSensors InterfacesWeight Scales
