Resumen del producto
MAX9939AUB+T is a general-purpose, SPI programmable-gain amplifier with input VOS trim and output op-amp. It features programmable differential gains from 0.2V/V to 157V/V, input offset-voltage compensation, and an output amplifier that can be configured either as a high-order active filter or to provide a differential output. It is ideal for conditioning a variety of wide dynamic range signals such as those found in motor current-sense, medical instrumentation and sonar data acquisition applications. Precision resistor matching provides extremely low gain tempco and high CMRR. Output amplifier is designed for high bandwidth and low-bias currents, making it ideal for use in multiple feedback active filter topologies that offer much higher Qs and stopband attenuation than Sallen-Key architectures. Applications include sensorless motor control, differential to single-ended conversion, differential-i/p, differential-o/p signal amplification, sensor interface and signal processing.
