Introduction

The MAX1080BEUP+ is a 3U analog to digital converter (ADC) module which is designed for military, aerospace and industrial applications. It has the capability to sample analog signals up to a frequency of 250MSps and can achieve a maximum resolution of 12-bits. The module’s power consumption is minimized through its low power architecture and high precision performance is maintained through its use of high performance low-noise amplifiers. The MAX1080BEUP+ is a part of the MILSTD-1553 or ARINC 429 serial communication interface packages and provides a cost-effective solution to high-speed data acquisition needs.

Application Fields

The MAX1080BEUP+ is ideal for use in both sideband and single-channel applications such as ground or airborne radar, engine control, avionics and flight control applications. In such applications, the module is used to convert analog signals into digital information. The module can also be used in automated test and measurement systems and in high-performance medical systems where high speed and accurate data acquisition is a necessity. The module is able to sample a single analog channel at rates of up to 250MSps, with a maximum resolution of 12-bits. In addition, the module is suitable for use in applications involving complex and wide bandwidths such as in multi-channel sound encoding and image capturing.

Working Principle

The MAX1080BEUP+ uses a combination of two “local active balancing amplifiers” and an input variable gain amplifier to achieve its high speed performance. The “local active balancing amplifier” is a low-noise voltage diffusor which is optimized for high speed operation. The module uses a low-noise variable gain amplifier to adjust the signal gain to precisely match the levels needed for the analog to digital conversion. This amplifier has the ability to adjust the gain of incoming signals in discrete steps in order to optimize their digital values, while simultaneously providing a stable reference source. This, coupled with the “LBA”s noise canceling abilities, allows the module to achieve excellent accuracy with low noise, significant enhancements of signal-to-noise (SNR) ratios, and allow for high sampling rates of up to 250MSps. The digital values can then be accessed by the application via a serial communication interface such as MIL-STD-1553 or ARINC 429.

Conclusion

The MAX1080BEUP+ is a state-of-the-art analog to digital converter (ADC) module which is designed for use in military, aerospace and industrial applications. Its low power consumption, high speed performance and high precision makes it an ideal choice for data acquisition needs in highly demanding environments. The module is capable of sampling a single analog channel at rates of up to 250MSps and a resolution of 12-bits and due to its use of low-noise amplifiers and a variable gain amplifier, its accuracy is more than adequate for such applications. The digital conversions are accessible over a MIL-STD-1553 or ARINC 429 serial communication interface, making it a cost-effective solution for various applications.
