MAX9945AUA+T - Brand New Maxim Integrated Instrumentation OpAmps
-
Description
The MAX9945AUA+T is an instrumentation operational amplifier that offers low operating power with a combination of low input voltage noise. The device supports low input bias currents and input current noise and features MOS inputs. The MAX9945AUA+T accepts a wide range of supply voltages, ranging from 4.75V to 38V, and has a quiescent current of 400µA. Additionally, it is unity-gain stable and can support rail-to-rail output voltage swing. The MAX9945AUA+T is ideal for portable medical and industrial applications that require a low noise analog front-end for high-performance applications such as photodiode transimpedance and chemical sensor interface circuits.
