The AD7892BRZ-3 is part of the Analog to Digital Converters (ADC) family of products by Texas Instruments. It is a monolithic CMOS, 10-bit continuous-time Σ-Δ A/D converter that has been developed for applications requiring a high level of system performance.

The AD7892BRZ-3 provides a single-ended analog input that gives a wide-range of resolutions from 8 bits to 10 bits, making the AD7892BRZ-3 ideal for highly accurate, low- to mid-resolution, data analysis applications. It also features a low power consumption and a fast data conversion speed.

The AD7892BRZ-3 is designed for applications such as energy metering, medical endoscopy, automotive automotive systems, robotics, industrial control, and audio recording and playback. With its excellent performance, the AD7892BRZ-3 can also be used in a variety of analog measurements, such as voltage, current, temperature, and pressure.

The working principle of the AD7892BRZ-3 is that it has a single-ended input consisting of 3 channels. The input is sampled at a user-defined rate and converted to a digital output. The ADC also features a programmable reference voltage, allowing the user to specify the voltage range to be measured.

The AD7892BRZ-3 is also capable of performing a “power-on” self-calibration, which allows it to connect to an analog sensor and automatically calibrate itself according to the external specifications. Once the calibration is finished, the ADC is ready for data acquisition.

The total conversion time for the 10-bit resolution is 27.6 μs, making it suitable for higher speed applications. Additionally, the converter is capable of providing up to 155μA low-current power consumption, making it ideal for portable applications.

To enable the flexibility of the converter, the AD7892BRZ-3 offers an I²C or SPI interface along with an external reset pin. With the I²C or SPI interface, the user can easily configure the AD7892BRZ-3 or retrieve the conversion result.

Overall, the AD7892BRZ-3 is an excellent A/D converter for applications requiring excellent performance and low power consumption, such as energy metering, medical endoscopy, automotive automotive systems, robotics, industrial control, and audio recording and playback.
