Analog-to-digital converters have existed since 1908, and since then have become increasingly integral in various electronics. One of the latest offerings in the world of analog-to-digital converters is the AD2S80ATD/B, a special purpose converter designed specifically to be used in motor control systems.

The AD2S80ATD/B is an 8-bit ADC that is able to convert a motor speed input signal into a digital feedback signal. With the ability to sample at a rate of up to 1 MHz and an operating voltage of 2.7 - 5.25 V, the AD2S80ATD/B is a suitable acquisition system for a wide variety of motor control applications.

The AD2S80ATD/B’s application fields include high accuracy motor speed control, position and speed servo loop control, and high resolution digital shaft encoders. The AD2S80ATD/B is also capable of converting a wide variety of signals, making it ideal for a variety of motor control systems. Examples of compatible signals include tachogenerators, resolvers, encoders, and various others.

The AD2S80ATD/B is able to achieve such a wide variety of applications due to its unique working principle. The AD2S80ATD/B is a variable-gain incremental ADC with a variable-gain preamplifier. As the motor speed input signal is converted, the amplifier’s gain is dynamically adjusted, aiding in the preservation of signal integrity. The gain is further enhanced by a differential output architecture, which allows for the highest accuracy of the output signal.

The AD2S80ATD/B is further enhanced with a programmable reference voltage in order to control the overall circuit power, aiding in power savings and efficiency. Additionally, the converter has a built-in comparator, allowing the output signal to be directly compared to an external reference voltage in order to generate a current feedback signal. The AD2S80ATD/B also has programmable digital thresholds, allowing users to set the output signal’s range to a predetermined voltage range.

Another significant feature of the AD2S80ATD/B is its low power requirements; the entire device can be powered by a single supply voltage between 2.7 and 5.25 V. This further enhances the device’s capabilities as a motor control system as it can be used in a variety of applications, from low voltage automotive systems to high voltage industrial systems.

In conclusion, the AD2S80ATD/B is a high-accuracy, low-power analog-to-digital converter that is an ideal choice for a variety of motor control applications. With its unique variable-gain preamplifier, programmable reference voltage, and comparator, the AD2S80ATD/B is able to provide an accurate, low-power feedback signal that allows for precise control of the motor. Additionally, its low voltage requirements allow for use in automotive and industrial systems alike, making it an excellent choice for motor control systems.
