Data acquisition refers to the process of collection, storage and interpretation of data from a given set of conditions. Digital to analog converters (DAC) are a type of device that can convert a digital signal into an analog signal. The DAC7718SRGZR is an integrated circuit (IC) designed for many applications using a high precision, low power, 16-bit voltage-output DAC. This IC provides excellent dynamic performance for integration and loop stability, interface and applications using analog circuitry.

The DAC7718SRGZR is suitable for a wide variety of applications in industrial settings including motor speed and torque control, test instrumentation, and waveform synthesis. It is also well suited for automotive applications such as power supply voltage and current control, engine control, and vehicle powertrain control. Additionally, it also may be used in medical devices, audio/video systems and defense electronics systems such as battlefield radar.

At the heart of the DAC7718SRGZR is the 16-bit DAC core. The 16-bit DAC core includes a low noise power supply, high speed reference input buffer, one DAC output channel, and a full-scale adjustment pin. This integrated circuit features high precision, low leakage, and low dynamic power consumption. The reference input buffer provides an interface for the analog-to-digital converter (ADC) as well as for an external reference voltage. The DAC output channel provides a voltage output with a resolution of 16-bit and a full scale accuracy of 0.2%. The full scale adjustment pin allows for the user to adjust the output voltage range from 0 to 5.5V.

The DAC7718SRGZR has a two-wire communication interface for setting and reading the DAC output voltage levels. This two-wire interface is compatible with the industry standard I2C protocol. The DAC7718SRGZR also features internal registers that control the DAC output and the various features of the DAC core. The internal registers have programmable options for soft start, power save mode, and limiting currents.

In addition to the DAC core, the DAC7718SRGZR IC contains a latch, an 8-bit digital-to-analog converter (DAC), and a control interface. The 8-bit DAC provides no less than 26dB signal-to-noise ratio (SNR). The latch is used to provide SPI or I2C compatible interface for set up of the output voltage level. The latch is also used to reduce the power consumption in the system. Last but not least, the control interface is used to provide interrupts when the DAC output voltage level reaches a certain threshold.

The DAC7718SRGZR is fabricated in a process of submicron CMOS technology enabling low power consumption, superior thermal/DC performance and improved system reliability. Operating on power supply voltage of 1.8 to 5.5 volts, the DAC7718SRGZR is specified over the industrial temperature range of -40°C to +85°C.

To conclude, the DAC7718SRGZR is an integrated circuit designed for many applications using a high precision, low power, 16-bit voltage-output DAC. It is suitable for a wide variety of industrial, automotive, medical, audio/video, and defense electronics applications. The 16-bit DAC core provides a low noise power supply, high speed reference input buffer and one DAC output channel with a full-scale accuracy of 0.2%. The integrated circuit also contains digital-to-analog converters, and multiple control interfaces for setting and reading DAC output voltage levels. Operating on power supply voltage of 1.8 to 5.5 volts, the DAC7718SRGZR is specified over the industrial temperature range of -40°C to +85°C.
