Data Acquisition - Analog to Digital Converters (ADC) is one of the most important components of modern day electronic systems. One of the leading products in this field is the AD7870JNZ, an integrated high performance, low-power 8-bit analog-to-digital converter (ADC). This integrated 8-bit ADC offers very high resolution and is an ideal solution for a variety of precision applications from automotive to industrial applications.

The AD7870JNZ is a fully integrated 8-bit analog to digital converter. It can convert analog signals with a dynamic range of up to 2.5V into 8-bit digital values. This device provides very low power operation, with typical power consumption as low as 0.37mW, and is packaged in a 4mm × 4mm QFN package. Its low power consumption makes it suitable for portable applications and battery operated systems.

The AD7870JNZ is designed with four selectable input channels, enabling simultaneous conversion of four channels with a total conversion time of 10µs. This device also features an integrated internal reference of 2.048V, which provides excellent repeatability, accuracy and low drift. Furthermore, the AD7870JNZ provides excellent linearity, with differential non-linearity (DNL) error of up to ±1 LSD, and Integral non-linearity (INL) error of ±2 LSB max.

The AD7870JNZ works by taking a continuous analog voltage signal as an input and sampling it at predetermined intervals. It then converts this voltage signal into a series of digital values, each one representing a certain value of the input signal. These values are then stored in a memory, ready to be read out when needed. The ADC then goes through the process of converting each sample into a digital word and then storing it in the memory until it has finished all the samples. The series of digital words are then ready to be read out of the memory by whatever system the ADC is integrated into.

Applications of the AD7870JNZ include automotive and industrial applications, where high precision and dynamic range are important. The device can be used in a variety of applications, ranging from motor control, instrumentation and robotics, to data logging and power supply monitoring. Other potential applications include medical and home automation devices, where the low power consumption and high resolution make it suitable for use.

The AD7870JNZ is a highly integrated 8-bit analog to digital converter that offers high precision, low power consumption and excellent dynamic range. Its four selectable input channels make it ideal for a variety of precision applications from automotive to industrial, and its integrated internal reference of 2.048V helps ensure excellent repeatability and accuracy. With these features and more, the AD7870JNZ is an excellent choice for precision data acquisition and conversion.
