The AD7984BCPZ-RL7 is a high-accuracy, ultra-low power, 3 MSPS, 12-Bit, Sigma-Delta ADC with an integrated, low-noise, voltage reference. It is highly suitable for portable systems requiring high performance, low power consumption, and high reliability. This device is capable of directly converting two simultaneous analog input voltages to digital outputs asynchronously.

The application field of the AD7984BCPZ-RL7 is widely used in various industrial and automotive applications, such as pressure and temperature sensors, weight measurements, and battery monitoring. In addition, the device has features like adjustable output voltage range, wide supply voltage range, above-normal input voltage range, self-calibration, and receive-only mode, which make it ideal for use in various biomedical and communications systems.

The working principle of the AD7984BCPZ-RL7 is based on a differential delta-sigma structure that consists of a loop filter, which is the main controllable element of the chip. The filter provides high conversion accuracy, even at low input frequencies. The device also has an on-chip reference and temperature sensor for high accuracy and stability. The temperature sensor is used to adjust the reference voltage offset to reduce fluctuation in the output over temperature.

There are two inputs that facilitate two analog-to-digital conversions. The analog inputs are connected to the differential inputs of the delta-sigma converter, which converts the input signals into digital codes. The input range is 0.9 to 3.6 V. The digital output can be programmed to be either a 12 or 10-bit result. The differential outputs are filtered through the programmable loop filter, and the outputs are synchronized to the clock applied at the start of each conversion.

The AD7984BCPZ-RL7 also includes an on-chip temperature sensor, so the reference offset can be adjusted to minimize errors due to temperature changes. The device is also capable of high speed operation up to 3 MSPS with fast settling time. It is compatible with a wide range of common microcontroller interfaces, such as SPI, I2C and UART. The device can be powered from a single 1.8V to 3.6V supply and provides ultra-low power consumption.

Overall, the AD7984BCPZ-RL7 is a high-performance, low-power, 12-bit sigma-delta ADC with an integrated, low-noise, voltage reference for applications requiring precision instrumentation, sensor measurement, and medical device applications. It has excellent performance, comprehensive features, and ease of integration, so it can be used with a wide range of microcontrollers.
