Analog-to-digital converters are one of the key elements of modern day analog signal processing. The AD7466BRTZ-R2 is an advanced and versatile analog-to-digital converter (ADC) specifically designed for precision signal acquisition and embedded control applications. The wide input common-mode range, high level resolution, low cost, and small size make it suitable for a variety of embedded control applications.

Application Fields of AD7466BRTZ-R2

The AD7466BRTZ-R2 is a single channel, 16-bit, low power, and low noise analog-to-digital converter that has a wide input common-mode range. This makes it useful in applications such as:

• Robotics – sensors such as gyroscopes, pressure transducers and cameras can be interfaced to robot control systems that can respond to changing conditions with precise accuracy.
• Automotive – the AD7466BRTZ-R2 can be used in automotive systems to digitize analog signals from vehicle sensors such as engine temperature, spark or exhaust pressure.
• Data Acquisition – the AD7466BRTZ-R2 can acquire precise analog data from a wide variety of applications, such as medical, industrial and scientific.
• Power Management – the AD7466BRTZ-R2 can be used to monitor and control power in consumer, telecom, and industrial applications.

The AD7466BRTZ-R2 is designed to operate down to 1.8 V and up to 4.9 V. Thus it is suitable for embedded control applications where low power and precise control is a necessity.

Working Principle of AD7466BRTZ-R2

The AD7466BRTZ-R2 is optimized for low power operation and high performance. It accomplishes this through its low noise internal analog-to-digital converter. The AD7466BRTZ-R2 utilizes a differential switch architecture combined with an internal Digital-to-Analog Converter (DAC) for low noise and low power operations. The differential switch architecture helps reduce self-heating and power consumption, while the internal DAC minimizes the need for an external reference. In addition, an integrated differential input stage helps reduce the noise and improve the common-mode rejection ratio.

The AD7466BRTZ-R2 also offers different modes of operation, such as pulse-width modulation (PWM), analog input, and digital input. In PWM mode, the ADC operates by sequentially switching the inputs between two predetermined levels. This mode allows for variable control of the input accuracy and power consumption. In analog input mode, the ADC compares the input signal to an internal reference voltage. This mode yields more accurate results, but consumes more power.

The AD7466BRTZ-R2 supports both single-ended and differential input signals. When using differential signals, the differential outputs are used to compare the input signal against the reference voltage. This helps reduce distortion, as well as increase accuracy. The AD7466BRTZ-R2 also supports output coding options, such as sign/magnitude and offset binary coding. Moreover, the ADC can sample inputs of up to 10kHz.

The AD7466BRTZ-R2 is a great choice for precision data acquisition, embedded control applications, and power management. With its low power, wide common-mode range, high resolution and small size, it is suitable for a variety of applications.
