ADC, or analog to digital converter, is an electric circuit used for encoding analog signals into digital signals. The ADS8555SPMR is a low-power, 16-bit, mid-speed, successive Apparoximation register (SAR) ADC, boasting the most advanced features including channel based parallel processing, channel-specific end-of-scan interrupts and power management. Used in a variety of applications, the ADS8555SPMR enables improved performance and greater flexibility in data acquisition.
Applications
The ADS8555SPMR can be used in a range of applications and markets, including industrial, automotive, healthcare, communications and consumer fields. Most common application areas include: sensor-based systems such as temperature, pressure, flow and humidity measurements, ground scanning, radar and ultrasound imaging, and motor control. The device can also be used in application involving small cell phone batteries, where low-power operation is important, and in low-power, accurate AD converters for short-term product integration.
Design
The ADS8555SPMR design includes many features that enable efficient system design. The device includes a wide dynamic range of 16 bits and 64dB, along with enhanced digital filter for noise reduction and attenuation of out of band signals. It operates over a 1.2V to 3.6V single-supply voltage range and additionally, an integrated bandgap reference provides an ultra low-noise signal, suitable for even the most sensitive analog input signals. The device also offers low power operation, consuming only 150mW at 3.6V.
Features
The device features many features that are attractive for data acquisition applications. It includes a self-calibration feature and a 0.25 LSB offset error. Additionally, the device includes a programmable gain amplifier (PGA) that allows adjustment of the gain and dynamic range of the signal. It also includes integrated channel-based parallel processing for accelerated read times and a channel-specific end-of-scan interrupt to alert of acquisition completion. As well, the device features built-in power management, allowing for optimal performance and operation depending on the application.
Working Principle
The working principle of the ADS8555SPMR is based on the successive Apparoximation register (SAR) ADC architecture. In this architecture, the digital and analog components are combined into a single structure. The analog input signal is applied to a track-and-hold circuit, which is used to store the sample of the signal. An analog to digital converter is then used to transfer the signal into a digital form. The output of the SAR ADC is a digital code, which is then sent to the digital processing total.
Conclusion
The ADS8555SPMR is a low-power, 16-bit, mid-speed, successful Apparoximation register (SAR) ADC, boasting the most advanced features. The device can be used in various applications, offering features such as enhanced digital filter for noise reduction, an integrated bandgap reference providing an ultra low-noise signal, and low power consumption. These features, along with its low-power and flexible design, make the ADS8555SPMR an ideal solution for a wide range of data acquisition applications.
