The recommended power-up sequence is to apply VCC first, followed by VEE. This ensures that the internal circuitry is properly biased and prevents any potential latch-up conditions.
To ensure accurate voltage reference output, it's essential to decouple the input pins (VIN and VREF) with a 10uF capacitor to ground. This helps to filter out any noise and ensures a stable reference voltage.
The AD558KNZ can drive a maximum capacitive load of 100pF. Exceeding this limit may cause oscillations or instability in the output voltage.
To minimize noise and interference, use a ground plane, keep the input and output traces short and away from noise sources, and use shielding if necessary. Additionally, consider using a low-pass filter or a ferrite bead to further reduce noise.
The thermal shutdown temperature of the AD558KNZ is typically around 150°C. If the junction temperature exceeds this limit, the device will shut down to prevent damage.
