ADL5562-EVALZ is an evaluation board specifically designed to evaluate the performance of the ADL5562 dual-channel, high-dynamic-range amplifier. It has many applications in audio and speech signal processing. In this article, we will discuss the application field and working principle of the ADL5562-EVALZ evaluation board.

The ADL5562-EVALZ evaluation board is ideal for use in low-power, high-dynamic-range amplifier applications, such as bridged or Differential-Input-Capable stereo systems. The board features a stereo power amplifier output and can be used to quickly and easily test the performance of the ADL5562 dual-channel, high-dynamic-range amplifier to make sure it meets or exceeds the requirements of the application.

The ADL5562-EVALZ evaluation board operates with a supply voltage range of 2.7V to 5V, and features on-board power-up sequencing, shutdown control, and fault monitoring capabilities. Additionally, this board offers adjustable gain and band-killing features, allowing the user to tailor the amplifier’s response to the specific application. The board also has a built-in power supply rejection, making it particularly well-suited for applications that require low noise performance.

The board also features a 6-pin Digital Control interface, allowing the user to easily set the gain, current limit, and other settings via an external control system. The ADL5562-EVALZ is also capable of operating in low-noise, low-power shutdown mode, which allows the amplifier to consume very low standby power when the signal is not present.

In addition to its audio and speech signal processing applications, the ADL5562-EVALZ evaluation board can also be used to evaluate other applications including robotics, telecommunications, and medical devices. The board is also well-suited for automotive and industrial environments, as it operates in temperatures ranging from -40° C to +85° C.

The working principle of the ADL5562-EVALZ evaluation board relies on the application of two, electrically-isolated, single-supply operational amplifiers. These amplifiers are capable of delivering 240 mW per channel of output power, with up to a 120 dB dynamic range and 117 dB SNR, depending on the gain settings. The amplifiers can be configured as either a bridge or differential-input configuration, with the bridge design providing up to six times the output current.

In summary, the ADL5562-EVALZ evaluation board is a powerful tool for evaluating the performance of the ADL5562 dual-channel, high-dynamic-range amplifier. Its stereo power amplifier output, adjustable gain and band-killing features, and 6-pin Digital Control Interface allow the user to quickly and easily test the amplifier’s performance for a variety of applications. Additionally, the ADL5562-EVALZ evaluation board has a wide range of application fields, making it an ideal choice for audio and speech signal processing, as well as robotics, telecommunications, and medical devices.
