Key Differentiators
- Military-grade processing (vs ADS774JU)
- Ceramic LCC package (vs AD574ATD/883B)
- Internal reference and clock (vs ADS774JU)
Design Notes
The AD574ATE/883B requires multiple supply voltages: +5V for logic, and Β±12V or Β±15V for the analog section. Ensure that these supplies are well-regulated and decoupled with 0.1uF ceramic capacitors close to the VCC, VEE, and VLOGIC pins. A 10uF tantalum capacitor on each supply is recommended for low-frequency noise filtering.
For optimal performance, use a ground plane and separate analog and digital ground areas, connecting them at a single point near the ADC. Keep analog input traces short and shielded from digital signals to minimize noise coupling. The LCC package has exposed pads; ensure proper soldering to the PCB for mechanical stability and thermal dissipation.
Do not exceed the absolute maximum ratings for supply voltages, as this can damage the device. Ensure that the analog input voltage does not exceed the specified range (0-10V or 0-20V depending on configuration). The internal reference is trimmed at the factory; avoid loading the REF OUT pin with low-impedance circuits, as this can degrade accuracy.
Compliance Information
Military-grade component, not RoHS compliant due to hermetic ceramic package.
