Key Features
- High Accuracy: The AD767KN maintains linearity errors of ±1/2 LSB over the full temperature range, ensuring high accuracy in analog output.
- Monotonicity: The DAC is monotonic over its full operating temperature range, meaning the output either increases or remains constant for increasing digital inputs.
- Low Digital Input Current: The low digital input current eliminates the need for buffer/drivers, allowing a single low-power Schottky gate to drive several AD767KNs when connected to a common bus.
- Positive-True Binary Input Coding: Uses straight binary coding for unipolar mode and offset binary coding for bipolar mode.
- Wide Temperature Range: Operates over a temperature range of 0°C to +70°C, with storage capabilities from –65°C to +125°C.
Applications
- Industrial Control Systems: Suitable for precision control in industrial environments due to its high accuracy and reliability.
- Medical Devices: Can be used in medical equipment where precise analog output is critical.
- Aerospace and Defense: The AD767KN's robust specifications make it suitable for use in military and aerospace applications.
- Automotive Systems: Used in automotive systems requiring high precision and reliability over a wide temperature range.
