The DS30EA101SQ/NOPB, is an interface circuit that combines an integrated 10-bit digital-to-analog converter with a high-performance voltage level translator. It is specialized to interface between systems operating at different logic and power-supply levels with a wide operating supply range, making it a versatile tool in various application fields.

Features

The DS30EA101SQ/NOPB has a unique feature of an adaptive offset-correction loop that adjusts the offset ‘on-the-fly’. This ensures that the Digital-to-Analog output remains perfectly calibrated over temperature and time. Another useful feature of the converter is its programmable current limit and power down mode that allows for easy configuration of the current limit for complying with the different system requirements. This feature makes the DS30EA101SQ/NOPB highly power efficient, giving it the versatility to work with consumer and commercial products alike.

Applications

The DS30EA101SQ/NOPB is specialized for interfacing between different logic levels, so it can be used in bus level conversion in digital audio, consumer electronics, medical diagnostics, test & measurement and like systems with ADC and DAC levels up to 5.0V. Data processors, industrial and automotive control systems, and other systems that require bi-directional logic level conversion can also benefit from the DS30EA101SQ/NOPB voltage level manipulator. Owing to its low power consumption and high performance, it can also be used in portable and battery operated products.

Working Principle

The DS30EA101SQ/NOPB is equipped with dual 5.0V output transistors and operates using a single supply voltage ranging from 5.0V to 30.0V. A symmetric bidirectional level transmitter is used to convert the TTL logic levels to CMOS logic levels. In addition, the device can also accept inputs from as low as TTL levels and drive output loads up to 50mA. The internal adaptive offset-correction loop adjusts the offset ‘on-the-fly’, ensuring that the output Digital-to-Analog output remains perfectly calibrated over temperature and time.

Conclusion

The DS30EA101SQ/NOPB Interface circuit is specialized to interface between systems operating at different logic and power-supply levels with a wide operating supply range, making it a versatile tool in various application fields. With its unique adaptive offset-correction loop, programmable current limit and power down mode, it is power efficient and highly reliable. It can be used in a wide range of application fields such as consumer electronics, medical diagnostics, data processors, automotive control systems, portable products and more.
