AD5662WARMZ-1REEL7 is a digital-to-analog converter (DAC) designed to provide highly accurate voltage and current outputs. It is ideal for applications requiring low power consumption and where low output offset and drift are important, such as in industrial, automotive, and medical applications.

Application Fields: The AD5662WARMZ-1REEL7 is suitable for many industrial applications including motor control, digital control systems, and factory automation. It is also suitable for automotive applications such as engine control, exhaust gas monitoring, and emission control. Additionally, it is well suited for use in medical devices, such as electrocardiogram and pulse oximetry systems.

Working Principle: The AD5662WARMZ-1REEL7 is a voltage/current output DAC, which uses a 12-bit precision current-steering architecture. This architecture provides high resolution and output accuracy, enabling it to achieve conversion linearity within 1 LSB total unadjusted error. The AD5662WARMZ-1REEL7 features an on-chip DAC reference, allowing the user to apply a reference voltage between 0.5 V and 5 V. The output voltage and current range of the ADC can be adjusted using an external programming voltage, allowing the user to customize the output range. Additionally, the on-board temperature sensor ensures that the output is stable over temperature.

The DAC offers low noise performance (typically 0.9µVrms across a 0-2.0V output range) and low power consumption. The low power consumption is enabled by a precise shutdown control for low standby current, as well as the use of a low voltage supply that can vary from 2.3 to 5.0V.

In addition to its low power consumption and high accuracy, the DAC is optimized for long term stability. It features a 0.005%/V supply voltage drift, a 0.2µV/°C temperature coefficient, and a ±10 ppm/year output drift. This makes it ideal for applications such as motor control and digital control systems, which require precise and stable performance over extended periods of time.

Furthermore, the AD5662WARMZ-1REEL7 features an integrated fault detection circuit, which provides a warning in the event of an over-voltage, under-voltage, or over-temperature condition. This eliminates the need for external protection circuitry, simplifying the design, and reducing board size and component count.

The AD5662WARMZ-1REEL7 is a highly integrated, low power, and highly accurate DAC, designed to meet the needs of a wide range of industrial, automotive, and medical applications. It has the accuracy and performance to handle even the most demanding applications, and its low power consumption and integrated fault detection circuit make it an ideal choice for low power and compact designs.
