PGA5807EVM is an evaluation and demonstration board and kit which is developed by Texas Instruments. It is used to demonstrate the application field and working principle of PGA5807, a precision amplifier that is able to achieve low noise and high precision. This evaluation board is comprised of a VGA5807, some of its related components, and test points for probing and demonstrating the working performance of the amplifier. It supports dual-supply, low-side gain setting, and output range adjustment to ensure superior accuracy.

The primary goal of PGA5807EVM is to evaluate and demonstrate the capabilities of PGA5807. Its application field mainly involves in consumer and automotive audio applications, including audio gain blocks, headphones, ADCs, and microphones. It also offers many performance advantages, such as low distortion and low noise, high gain accuracy, high supply voltage tolerance, low total harmonic distortion, and low offset voltage.

The working principle of PGA5807EVM is based on its main component, the PGA5807. This is a precision amplifier which is capable of achieving low noise and high precision. It is designed to be operated in either single-end mode or differential-end mode. In single-end mode, the input signal is connected to one of the inputs. The output is taken from the other input. In differential-end mode, the inputs are connected to the two ends of a differential signal, and the output is taken from the center of the differential signal. It features low-side gain setting and output range adjustment that allows adjustment of gain by setting the voltage at the low-side gain setting pin, and of the output range by setting the voltage at the output range adjustment pin.

The PGA5807EVM evaluation board features a test point labeled “Output Range Adjust,” which can be used to adjust the range of the output signal. It also has a test point labeled “Low-side Gain Setting,” which allows adjustment of the gain of the amplifier. It features an easy-to-use user interface and a high input signal range of ±12V. Additionally, it supports a wide supply voltage range of ±15V. Moreover, it includes protection circuits, such as an over-temperature protection circuit, a short-circuit protection circuit, and an overload protection circuit, that can protect the amplifier from damage.

In summary, the PGA5807EVM is an evaluation and demonstration board and kit from Texas Instruments. It is primarily used to evaluate and demonstrate the application field and working principle of PGA5807. This evaluation board is comprised of a PGA5807, some of its related components, and test points for probing and demonstrating the working performance of the amplifier. It features an easy-to-use user interface, a wide supply voltage range, high input signal range, and protection circuits. Thus, it is highly suitable for consumer and automotive audio applications.
