THS4062EVM is an evaluation module designed with precision CMOS operational amplifier, THS4062, offering low power consumption and low noise audio operation. The evaluation module allows users to experience low-power audio performance with minimal performance deterioration. This evaluation module provides an ideal platform for evaluating THS4062 in applications including portable instrumentation, line drivers, data converters, and many other audio-related applications.

The THS4062EVM board includes two sections. The first section is devoted to the THS4062 Op Amp. It has two amplifier channels and six user-selectable gains. For adjustable gain applications, use two on-board potentiometers to adjust the gains of both channels independently. Additionally, two pins are available for external gain control. The board also includes two sets of connectors, allowing the user to easily connect an audio source or external load for testing the THS4062. The second section is devoted to power management. It incorporates two 3.3V LDOs and four regulators. These provide the user with necessary power for the operation of the THS4062 and other external devices.

The THS4062EVM board enables users to quickly and easily evaluate the performance of the THS4062. The evaluation board is based on the TI TPA025CM op-amp, to ensure the cells’ robustness and accuracy. Inputs to each channel can be driven with a low impedance audio signal source and are DC coupled. The THS4062EVM provides an output impedance of ~20 ohms and a gain of up to 20 dB. The THS4062EVM also provides a high output current capability and low distortion performance. Additionally, it contains synchronous audio compensation, over-temperature monitoring, and power-on reset.

The THS4062EVM also includes special features that permit the user to customize performance to meet specific requirements. These include controlled frequency response, dynamic range, and power consumption. The board includes a dedicated test point for measuring quiescent current and an on-board test signal generator, allowing the user to directly measure the THS4062 performance. Furthermore, the board includes an adjustable power supply voltage, thus allowing the user to increase or decrease the supply voltage and change the output power level. The board also includes a short coding interface for accessing the internal control registers.

The THS4062EVM provides a powerful and cost-effective platform for evaluating the low power, low noise audio performance of the THS4062. Its dedicated features offer the user the flexibility to easily customize performance and design their own applications. The board allows the user to experience the performance of the THS4062 quickly and easily, making the evaluation of new designs and applications simpler and faster.
