AD7868BNZ is a high-performance, low-power, 8-bit, 10-channel analog-to-digital converter that operates from a 2.0V to 5.5V supply and includes an internal voltage reference. It is specially designed for light sensing applications such as general purpose and medical imaging devices. This device is based on successive approximation principle and is characterized by high resolution, good linearity and low power. The resolution of the device is 8 bits and it can measure a 0.75V or 1V full-scale differential input. It has a 10-bit resolution channel and 10 channels of analog inputs including 8 single ended and 2 differential inputs.

The AD7868BNZ is an ideal analog-to-digital converter for applications that need high speed, low power, and accuracy. It has an auto-zero reference and an internal clock that can be programmed and adjusted to the user’s desired speed. This converter has an over-range status flag which allows the detection of invalid conversions. It also has an array of digital output formats, including serial SPI and parallel outputs. An on-chip temperature sensor is also integrated for use in correction of analog data.

The main features of AD7868BNZ are its low power consumption of typically 4.5 mW, its very small 4mm × 5mm × 0.3mm package and its 10 adaptable input channels that cover a wide range of applications. Its extended input voltage range from 2.0V to 5.5V makes it suitable for use in 1.8V systems as well. The converter also has an industry-standard SPI control and data interface, which makes it easy to use. This allows an accurate and fast responses even in demanding applications such as medical imaging and industrial sensing.

The ADC has a wide temperature operating range and is suitable for use in harsh environments. The device works with a single current system and can operate over a wide range of supply voltages. It also has an integration time ranging from 40μs to 230μs. The device is programmed by a serial interface that can be used to read and write code blocks, which sets the analog front-end for the desired range of measurements.

The AD7868BNZ is highly reliable and can replace existing ADCs as it meets most of the industry requirements. It has very low power consumption and is a highly integrated device supporting a full range of input ranges and gain selections. The 8-bit resolution results in high accuracy and with its low noise level it is an ideal device for high-frequency signals. The device also has excellent linearity and no missing codes. In addition, it has internal self-test capabilities and auto-zero capabilities to ensure reliability.
