Data acquisition describes the process of sampling signals that measure real-world phenomena and converting the data into digital numeric values that can be manipulated by a computer. Data acquisition systems enable us to create more effective and efficient designs, products and processes. Digital to analog converters (DACs) are often used in data acquisition systems to convert digital signals into analog signals. The DAC7513E/2K5 is one such device covered in this article that is used to convert digital signals into analog outputs.

Overview

The DAC7513E/2K5 is a single channel, 8-bit digital to analog converter that consists of 256 levels of these 8-bit data inputs. It is a low-cost, low-power device that is often used in industrial data acquisition and control applications. The device also includes a serial port for programming the gain and offset parameters along with some other functions. It operates on a single +5 V supply and is able to produce a full-scale output voltage range of between zero and 4.095V. It also has an operating temperature range from -40 to +85°C.

Working Principle

The DAC7513E/2K5 provides an 8-bit digital input that is used to store the 8-bit data values. When the input data is valid and the device is enabled, the output voltage is determined by the current value of the digital input. The voltage output is determined by the eight bit value and the reference voltage. For example, if the input has a value of FFh, the output voltage will be 4.095V, while if the input has a value of 00h, the output voltage will be zero volts.

Features

The DAC7513E/2K5 has a number of features, including:

• 8-bit resolution for use in precision control and data acquisition systems.
• High linearity across the full scale output range.
• Able to operate on a single +5V supply.
• Low-power operation with a power dissipation of only 30 mW.
• Compact 14-pin SOIC package.
• Compatible with standard interfaces such as SPI, I²C, and UART.

Applications

The DAC7513E/2K5 provides a high dynamic range and excellent signal-to-noise ratio, and is suitable for a range of industrial applications including:

• Data acquisition systems.
• Precision control and monitoring.
• Analog signal conditioning.
• Motor control.
• Industrial instrumentation.
• Power supply and system protection systems.
• Sensor and actuator control.

Conclusion

The DAC7513E/2K5 is a low-power, 8-bit digital to analog converter suitable for a range of data acquisition and control applications. It features 256 level of resolution setting with a linear output that produces full-scale outputs of 0–4.095V. It is able to operate on a single +5V supply and is available in a compact 14-pin SOIC package. The device is also compatible with standard interfaces such as SPI, I²C, and UART, making it an ideal solution for industrial applications requiring precision control and monitoring.
