The AD698SQ is a low-cost, high-performance mixed-signal analog front-end (AFE) IC for data acquisition and control applications. It features a 12-bit A/D converter, 16-bit pulse-width modulator (PWM) output, a 12-channel programmable analog input multiplexer, and five internal signal conditioning blocks to condition signals and extract features. The AD698SQ is ideal for applications in data acquisition and control, such as industrial touch panels, pressure sensors, and high speed data acquisition systems.

The AD698SQ belongs to Interface - Sensor and Detector Interfaces, which are used to interface to analog sensors, detectors and converters with a digital signal processor or microcontroller. The major application areas of such an interface are industrial control, consumer electronics, automotive electronics, military and aerospace. With respect to the versatile functionalities of the AD698SQ, the device is well suited for applications found in these industries.

The working principle of the AD698SQ is quite simple. It has 16 analog input channels connected to an Analog-to-Digital Converter (ADC) via a multiplexer. The ADC converts the analog values across these channels into digital values. The output from the ADC is sent to a Digital Signal Processor (DSP) or a microcontroller. The DSP or the microcontroller can then use the digital values to control or monitor a system or process. The AD698SQ also has the capability to output the digital values collected by the ADC as Pulse Width Modulated (PWM) pulses. This feature allows for precise control of external components such as motors and actuators.

Furthermore, the AD698SQ has a number of internal signal conditioning blocks. These blocks enable the device to condition signals and extract features. For example, the ADC can be connected to a motion sensor to detect motion changes and convert them into digital signals. The signal conditioning blocks can then be used to extract features such as acceleration or velocity. Other features can be used to determine the orientation or direction of movement. The AD698SQ also has analog output capabilities, allowing it to control external components such as motors or relays.

In summary, the AD698SQ is an ideal solution for a variety of applications in industrial control, consumer electronics, automotive electronics, military, and aerospace. Its 12-bit A/D converter, 16-bit PWM output, 12-channel programmable analog input multiplexer, and five internal signal conditioning blocks enable the user to effectively condition signals and extract features. Its PWM output feature can be used to accurately control external components, such as motors. The AD698SQ is a versatile Interface - Sensor and Detector Interfaces that makes it easy to acquire, monitor, and control signals from sensors and detectors in a wide variety of applications.
