Introduction

The DAC8501E/250 is a low-cost Digital to Analog Converter (DAC) designed to convert an 8-bit digital word to an output voltage. The device is a single channel, 8-bit monolithic DAC, with a 250 kHz data input rate with a serial output. The DAC8501E/250 is provided as a compact surface-mount package.

Application Fields

The DAC8501E/250 is used in data acquisition and control systems where a digital to analog conversion is required. Typical applications include implementing antilog amplifiers, precision DACs, analog-to-digital converters, voltage references and DAC buffers.Due to its low noise level and accurate 8-bit resolution, the DAC8501E/250 is suitable for applications in medical instrumentation and imaging, industrial process control and control systems. The device is also ideal for a wide range of consumer and automotive applications, including instrumentation and audio systems.

Working Principle

The DAC8501E/250 works by converting an 8-bit digital word into an analog voltage. The device can receive data at a rate of up to 250 kHz and can produce an analog output voltage between 0V and 4.096V.To achieve this, the device uses a low-pass RC filter which integrates the digital word into an analog voltage. This is followed by an output amplifier which buffers the analog voltage.The device also includes an internal reference voltage which is used to determine the conversion accuracy for the device. The reference voltage is internally-generated and is stable over temperature.

Benefits of using the DAC8501E/250

The DAC8501E/250 is designed to offer excellent accuracy, low noise, and fast settling time. Thermal drift and power supply rejection ratio are excellent. The output amplifier and reference voltage are low-power and can provide a stable, low-noise output over a wide range of temperatures.The device is also designed for ease of use and quick implementation. The 8-bit parallel and serial data inputs make implementing the device in a system simple and quick.

Conclusion

The DAC8501E/250 is an ideal choice for a wide range of applications. The device is low cost, low power and offers excellent accuracy and fast settling time. It can receive data at a rate of up to 250 kHz and can produce an analog output voltage between 0V and 4.096V. By incorporating an internal reference voltage, the device ensures excellent conversion accuracy and stability over temperature.
