MAX5852ETL+T Application Field and Working Principle

Data Acquisition - Digital to Analog Converters (DAC) are electronic components used to change an input signal from digital to analog form. The MAX5852ETL+T is a DAC of this type, and its application field and working principle will be discussed in this article.

Application Field

The MAX5852ETL+T is a sample-and-hold, 16-bit DAC module. It has a specified maximum temperature coefficient of 0.12 ppm/°C and typically offers low distortions over the 0 - 20 kHz range. This makes the device suitable for applications such as audio paging and communication, where precision and low distortion are required. It is also suitable for high-end audio processing, monitoring, VCA and EQ, as well as applications in medical, automotive and aerospace systems.

Working Principle

The MAX5852ETL+T uses a differential-binary (DB) architecture to perform the conversion. It takes a digital input representation of a voltage or current, and converts it to a corresponding analog output. In the DB architecture, the analog output is proportional to the sum of the individual digital input signals, and is highly accurate up to a few degrees of error. The voltage reference is connected to the input pins, allowing for a wide range of input voltages.

The module includes a static spur-canceling technique, which reduces the startup and shutdown glitches on the analog output. This solution provides clean switching response and helps to eliminate any source of harmonic distortion, resulting in higher accuracy. The module also includes an internal voltage reference, which is capable of providing up to 5V at its output. The module is capable of driving up to 500mA of current, making it suitable for drivingpiezo transducers and haptic motors.

Conclusion

The MAX5852ETL+T is a 16-bit, sample-and-hold DAC module suitable for precision applications in audio paging and communication systems, as well as in medical, automotive and aerospace systems. Its differential-binary architecture and static spur-canceling technique provide clean switching performance and improved accuracy. The module is also capable of driving up to 500mA of current, making it capable of powering even the most demanding circuits.
