The EK37 evaluation board is a high-performance evaluation tool that can accurately measure the static and dynamic characteristics of op amps for various applications. The EK37 board set includes a comprehensive set of test instruments and associated accessories, such as a power supply, signal generator, test oscilloscope, and test jigs. This evaluation board is suitable for characterizing a wide range of configurations such as single-, dual-, and quad-channel op amps.

The EK37 evaluation board uses a feedback loop connection to measure op amp responses. This feedback loop consists of an input amplifier and an output amplifier. The input amplifier provides the input signal to the op amp and the output amplifier senses the output of the op amp. By measuring the gain, phase and drift of the feedback loop, the op amp’s response can be accurately determined.

The EK37 evaluation board can measure a variety of parameters for op amps, such as supply voltage, common-mode rejection ratio, output polarity, offset voltage, open-loop gain, and bandwidth. In addition, it can also measure the power consumption, temperature drift, and frequency response of the op amp. The board has two dedicated inputs to measure the power consumption and temperature drift of the op amp.

The EK37 evaluation board also has the capability to measure the distortion of an op amp under various conditions, such as sine wave, square wave, triangular wave, and other waveforms. For each waveform, the EK37 evaluation board has dedicated inputs to measure the distortion of the op amp. By measuring the distortion, designers can gain insight into the performance of the op amp under various operating conditions.

The EK37 evaluation board can also be used to characterize linearization, noise, and power supply rejection. Linearization refers to the ability of the op amp to operate linearly over its input and output range, while noise refers to any unwanted signals present in the system. Power supply rejection is the ability of the op amp to reject any perturbations in the power supply. By measuring these parameters, designers can optimize the performance of the op amp for their applications.

The EK37 evaluation board is a powerful and versatile tool to characterize op amps for various applications. With its comprehensive set of test instruments and associated accessories, the board provides engineers with a reliable platform to analyze the performance of op amps. By measuring parameters such as linearization, noise, and power supply rejection, designers can understand the performance of the op amp under different conditions and optimize it for their applications.
