The MAX9945EVKIT+ from Maxim Integrated Products is an evaluation kit for MAX9945 low noise, MOS input, low power op-amp. The MAX9945 operational amplifier features an excellent combination of low operating power and low input voltage noise. In addition, MOS inputs enable the MAX9945 to feature low input bias currents and low input current noise. The EV kit provides a proven design to evaluate the MAX9945 op amp in an 8-pin FMAX package. Various test points are provided for easy evaluation. The EV kit circuit is preconfigured as a transimpedance amplifier (TIA) but can easily be adapted to act as a noninverting, inverting or differential amplifier by changing a few components. MOS input bias currents, low input voltage noise and rail to rail output stage make this device ideal for photodiode transimpedance amplifiers, piezo buffers and audio line out applications. The components have pads that accommodate 0805 packages, making them easy to solder and replace.
