Digital data acquisition has become increasingly popular as technology advances, and analog-to-digital converters (ADC\'s) are essential components in the process. ADC 08832IM is a Monolithic signal conditioning Analog-to-Digital converter. In this article, we will discuss the application field and the working principle of ADC 08832IM, and how it can be used in data acquisition.

Application Field

The ADC 08832IM is an integrated signal conditioning Analog-to-Digital converter, designed to provide a high level of integration. It consists of a low offset, low drift operational amplifier, a precision 5-bit counter and a fast CMOS-based switching matrix. This ADC is suitable for applications that require low power consumption and high accuracy. Examples of applications include:

• Industrial Control
• Medical Instrumentation,
• Automated Test Equipment,
• Data Acquisition Systems,
• Voltage-to-Current Conversion.

The ADC 08832IM is ideal for applications that require the conversion of voltage or current signals with four or more bit resolution. It is capable of converting input signals ranging from 1 mV to 15V.

Working Principle

The ADC 08832IM is based on a five-bit binary-weighted voltage divider architecture, with each bit corresponding to a different voltage division. The input signal is applied to the low-offset, low-drift operational amplifier, which buffers and amplifies the signal. The amplified signal is then divided into five output signals, each one corresponding to a different voltage division. These output signals are then compared to the reference voltage, and the closest matching division is determined.

The output of the switching matrix is then sent to the 5-bit counter, which counts up from 0 until the comparison is made. The output of the counter is then used to generate the digital result represented as a four-bit binary word. This four-bit word is then converted to either a decimal or ASCII code, depending on the application.

The ADC 0882 IM provides a high level of integration of signal conditioning and analog-to-digital conversion in a single component. This allows the converter to be used in a wide range of applications, including industrial control, medical instrumentation, automated test equipment, and data acquisition systems. The ADC 0882 IM also provides a low power consumption and a high resolution, making it an ideal choice for applications that require accurate and reliable data conversion.
