DAC5675IPHPG4

The DAC5675IPHPG4 is a monolithic integrated device for data acquisition and digital to analog conversions, which is used in various applications and industries. The device has two power supply options that provide galvanic isolation between the digital and analog sections, allowing for a true differential output.

The DAC5675IPHPG4 is a true differential output, current-mode Digital to Analog Converter (DAC). It has 18-bit resolution and provides a 12-bit differential output current range. It uses a proprietary architecture to achieve a very high linearity and dynamic range, with a high degree of immunity to digital and analog noise. The output current range of the DAC5675IPHPG4 can be adjusted from ±2.5 µA to ± 625 µA.

The DAC5675IPHPG4 is most commonly used for applications such as communications, process control, motor control, medical imaging, and medical instrumentation. The device can also be used in industrial control systems, digital image processing, aerospace and defense applications, and in other applications where a high level of precision, accuracy, and linearity is required.

The working principle of the DAC5675IPHPG4 is based on the concept of generating a differential output current based on the digital input code. The device consists of a controller, a high speed digital-to-analog (DAC) converter and a ratio-metric amplifier.

The controller translates the digital input data into a corresponding analog signal code. This code is fed to the high speed DAC, which then converts the signal into an analog voltage. This voltage is then amplified and buffered by the ratio-metric amplifier, to generate the desired differential output current.

The DAC5675IPHPG4 also features a wide bandwidth, with a settling time of 2µs for 10-bit resolution and 50µs for 18-bit resolution. The device has a low power consumption of typically 288 mW, and a low temperature drift of 20ppm/ºC.

In conclusion, the DAC5675IPHPG4 is an ideal device for applications that require high-speed, high-linearity and accuracy. Its versatility and ease of use make it a suitable choice for both industrial and consumer applications.
