The ISLA224P12IRZ is a high-performance integrated analog-to-digital converter (ADC) for use in data acquisition, signal processing and communication applications. With a 12-bit resolution and a sample rate of 500kHz, this ADC offers excellent dynamic performance, a wide range of input ranges and low power consumption. The ISLA224P12IRZ is ideal for applications where precise data acquisition and low noise operation are essential.

Description

The ISLA224P12IRZ is a single-chip, monolithic, laminated CMOS integrated circuit designed to provide a high resolution and low noise analog-to-digital conversion. It offers a 12-bit resolution, 500kHz sampling rate, and a wide range of input ranges. Its low power consumption and low noise performance ensure it can be used for a variety of demanding applications, such as data acquisition, signal processing and communications.

The ADC consists of a single converter block with an integrated 12-bit DAC, three independent multiplexers, and a 12-bit output data latch. It has extended temperature range operation and a wide supply voltage range of 3V to 10V. The converter block provides a direct conversion of an analog signal to a digital representation. The multiplexers provide flexibility by allowing different input ranges to be chosen. In addition, the digitally-controlled switches can be used to select various gain and offset configurations for the sample and hold timing and for the correction of the DAC transfer function. The output data latch is used to store the conversion results during the sampling period.

Working Principle

The ISLA224P12IRZ ADC can convert an analog signal to a 12-bit digital representation with a sample rate of 500kHz. The digital representation is stored in the integrated 12-bit latch, which enables the converter to simultaneously acquire and convert two analog input signals. The multiplexers allow for multiple selectable input ranges; this allows for a wide variety of signal amplitudes and frequencies to be processed.

The ADC module consists of a 12-bit data latch, three multiplexers, and a low-noise, high-resolution ADC. The multiplexers select between the different input ranges, allowing the desired signal to be accurately represented in the digital domain. The low-noise ADC performs the main signal conversion, providing a 12-bit representation of the received signal. The data latch is used to store the converted values until they are read. Once the data has been read, the ADC resumes its conversion of the next sample.

Applications & Advantages

The ISLA224P12IRZ is suitable for a variety of data acquisition, signal processing, and communication applications. It is ideal for applications with demanding noise performance, where low power consumption is required. Its 12-bit resolution allows for accurate reconstruction of signals, and its fast sampling rate ensures that signals can be accurately represented in the digital domain.

The ADC provides advantages in applications where temperature stability is needed. Its wide temperature operating range provides reliable operation in extreme temperature conditions, while stable resolution and low input-referred noise remain intact. Additionally, its low power consumption enables it to be used in battery-powered or portable applications.

Conclusion

The ISLA224P12IRZ ADC is a high-performance, monolithic integrated circuit with 12-Bit resolution and low power consumption. Its wide input range, low noise performance, and extended temperature operation make it suitable for a variety of demanding applications, such as data acquisition, signal processing and communication. Its fast sampling rate of 500kHz and wide temperature operating range allow it to be used in extreme temperature conditions.
