Evaluation and Demonstration Boards and Kits are becoming ever more important for technology-driven fields. In particular, PGA2500EVM has been a particularly successful product given that its application fields and working principle have enabled greater innovation within the equipment markets and product development. As such, this article will discuss the PGA2500EVM boards, its possible application fields, and provide some insight into its working principle.

PGA2500EVM are equipped with dual-map 8KCMOS Programmable Gain Amplifiers and allow for extremely varied applications, such as mixed signal, audio, industrial, automotive, medical and military/aerospace processing of signals. These boards feature excellent input and output protection (up to 40V/25A) and a wide power supply range (from 4V to 24V). In addition, the amplifier can be quickly configurated whilst using the popular Texas Instruments\' Eval Software, this allows for the user to either access an uncomplicated GUI or to use command-line functions to modify features in the board.

It offers three output range amplifiers (3.0V, 5.0V, and 10V). Moreover, these boards have excellent sound quality and are able to achieve high performance levels - the headroom of the amplifier is extra wide at + 36 dB for a given input. Furthermore, the amplitude tracking of the gain stages of PGA2500EVM board is highly precise at 0.001%.

The amplifier has often been praised for its unit size; the entire package is only 51mm2 in area. This incredible size not only makes shipping of the board less expensive, but it also enables greater versatility when manufacturers look to use their product either for smaller or bulkier build-outs. The amplified signal is also surprisingly high fidelity, often surprising industry experts in their listening test.

Moving on to the working principle of the board, it is easy to understand with a little bit of explanation. The device is configured using the popular Texas Instruments’ Eval Software; PGA2500EVM boards are powered with a 5V supply voltage. During operation, the 5V energizes the internal resistor which acts as the gain element within the device. As the amplifier receives an input signal, it moves from one gain stage to the other. This usually means that the voltage level is proportionally increased as the output is dependent on the input signal. This amplification process enables manufacturers to amplify signals much more easily and quickly.

PGA2500EVM boards also incorporates features such as temperature control and programmable output drive levels. This allows the board to respond to any environmental variance and to maintain peak accuracy. In addition, the board contains on-chip protection circuitry which prevents any short-term disturbances in the signal. Lastly, the advantages of the amplifier are enable accurately reproduce the low-frequency elements of the signal as well as controlling the non-linear resonance common in many high-frequency elements.

In conclusion, PGA2500EVM boards are incredibly versatile products, able to respond to a number of application fields such as mixed signal, audio, industrial, automotive, medical and military/aerospace processing of signals. They are small in size, provide excellent sound quality, and can be easily configured through the popular Texas Instruments\' Eval Software. Additionally, the boards contain on-chip protection circuitry, temperature control, and enables accurately reproduce the low-frequency elements of the signal. All these factors point to PGA2500EVM boards being a highly successful product.
