Analog to Digital Converters (ADC) are used to convert a continuously varying “analog” signal into a numerical form that can be used by digital systems. One of the most commonly used analog to digital converters is the AD7893BNZ-2, which is a single-channel, high-precision, low power device that is manufactured by Analog Devices. This device is primarily used in a variety of portable medical and industrial applications, such as glucose monitoring, medical implantable devices, and pressure sensors. In this article, we will discuss the application field and working principle of the AD7893BNZ-2.

The AD7893BNZ-2 is specifically designed for high resolution analog to digital conversion. It offers a wide range of input voltage levels, programmable gain selections, and a high speed serial output. This device is well-suited for use in low-power, battery powered applications that require accurate measurements of temperature, pressure, and other physical parameters. The AD7893BNZ-2 is also capable of digitizing signals with a range of ±10 VDC, eliminating the need for additional signal range limitations. Furthermore, the device is designed to provide the highest level of accuracy and performance in the harsh conditions of a wide range of medical and industrial environments.

The AD7893BNZ-2 features an on-chip 8-bit Digital/Analog Converter (DAC). This DAC is capable of accurately encoding a voltage or current input signal into a digital data format. The ADC is also equipped with an on-chip analog-to-digital converter that is used to convert the analog signal into a digital format. The ADC also includes a low power reference voltage for accurate and stable data measurements. Furthermore, the device includes a precision voltage reference for linearity and temperature stability over the full operating temperature range.

The AD7893BNZ-2 is also designed with a variety of output modes to ensure that it can easily integrate with a wide range of systems. The device utilizes a Serial Peripheral Interface (SPI) with a parallel output; this allows the data to be quickly transmitted over a serial bus. The device also has a range of digital filters to reduce noise and provide a constant data rate. Additionally, the device supports a wide range of power saving schemes, including power-down and sleep modes, which greatly reduce the operating power of the system.

The AD7893BNZ-2 is also capable of handling very wide input ranges. The ADC includes an analog input range of up to ±20V, allowing it to detect minute changes in the signal. Furthermore, the ADC can handle a maximum differential input range of ±1.25V, ensuring that it can accurately capture small changes in the signal. The ADC also includes an input offset voltage adjustment option for further accuracy.

The AD7893BNZ-2 is an ideal choice for applications that require high accuracy, low power operation, and a wide range of input ranges. It is an excellent solution for use in portable medical and industrial devices, such as glucose monitoring, medical implantable devices, and pressure sensors. It is designed to provide the highest level of accuracy and performance in harsh conditions, and its SPI interface and digital filters make it easy to integrate into existing systems.
