AD7789BRMZ, or Analog-to-Digital Converters (ADCs) are used to convert analog signals—such as audio or sound waves—into a digital representation of the signal’s voltage levels or amplitudes. The AD7789BRMZ is an integrated, high-speed, low-power, low-functional-noise, CMOS successive-approximation ADC. It converts analog input signals into 16-bit digital words with a wide dynamic range of 78 dB and a signal-to-noise-and-distortion ratio of 89 dB.

The AD7789BRMZ has an integrated voltage reference and multiple low-noise linear-amplification stages to improve signal-to-noise ratios and reduce the total power needed to drive the signal chain. It is designed for use in portable and embedded designs, where small size and low power are key features. Its features include an integrated voltage reference, low-noise amplifiers, and an integrated anti-aliasing filter.

The AD7789BRMZ operates over a wide range of input frequencies from DC to 1 MHz. The signal-to-noise ratio is better than 89 dB. This is an operational amplifier (op amp) ADC that performs the conversion in a single-ended mode. Its low power consumption, fast conversion speed, and low power requirements make it ideal for applications such as mobile phones, portable medical instruments, and battery-powered test equipment.

The working principle of the AD7789BRMZ involves the use of a charge-redistribution technique. In this technique, the input signal is converted to digital words without any prior knowledge about the conditions of the analog input signal. The charge-redistribution algorithm works by taking the differences between the successive approximations and the analog input signal, and then generating a corresponding digital code.The AD7789BRMZ is capable of achieving resolution up to 16 bits, depending on the digital system design and integration. This facilitates seamless integration into digital systems that require higher resolutions and trustworthiness.

The AD7789BRMZ has a variety of potential applications in the data acquisition industry. It can be used to measure electrical currents and voltages in remote locations, as well as in audio and video recording and playback, process control, and communication systems. It can also be used in automotive and medical instrumentation, instrument navigation, and other instrumentation applications, as well as industrial and consumer electronics. Moreover, due to its low-power consumption and excellent SNR, it is suitable for applications that require frequent readings.
