Application Field

The MAX128AEAI+T is most commonly used in applications where accurate, high-speed digital conversion is desired. In applications such as frequency synthesizers and direct digital synthesizers, the MAX128AEAI+T offers very high-performance characteristics. In addition to high-speed digital conversion, the MAX128AEAI+T also offers low-noise and low-change speed. This feature is beneficial in applications where the slightest variations in frequency are not tolerated, such as RF filters and spectrum analysis.

The MAX128AEAI+T is also well-suited for applications needing reliable and accurate temperature measurement. The on-board temperature sensor has a high accuracy, making it suitable for a variety of temperature measurement applications.

Working Principle

The MAX128AEAI+T utilizes gate array technology to perform frequency synthesis and digital-to-analog conversion (DAC). The gate array consists of a plurality of configurable digital blocks, a low-noise high-speed operational amplifier, and an on-board temperature sensor.

To generate a desired frequency, the user programs the gate array with the desired scaling, frequency, and duty-cycle parameters. These parameters are used to program the frequency, low-noise amplifier, and DAC blocks. Once programmed, each block operates in parallel to generate the desired frequency.

The low-noise operational amplifier is especially suited for applications where the slightest variations in frequency cannot be tolerated. Its low noise floor ensures that any small changes in the input signal are accurately reflected in the output signal.

The on-board temperature sensor allows the MAX128AEAI+T to make accurate temperature measurements. The temperature sensor has a high accuracy, allowing it to measure temperatures ranging from -40°C to +125°C with a minimum resolution of 0.0025°C.
