Key Differentiators
- High-temperature rating up to 210°C (vs ADS8320)
- Ceramic package for reliability (vs ADS8320)
- Micropower operation (vs ADS7816)
Design Notes
Ensure proper decoupling of the VCC and VREF pins with 0.1µF and 10µF capacitors placed close to the device. This maintains reference stability and reduces noise, which is critical for 16-bit accuracy.
The ceramic package is designed for high-temperature operation, but thermal management is still important. Ensure adequate heat sinking or airflow when operating near 210°C to prevent thermal stress and maintain accuracy.
For noisy industrial environments, consider isolating the SPI interface using digital isolators such as ISO1540D. This prevents ground loops and electromagnetic interference from corrupting the serial data.
Compliance Information
Compliance information not provided in the verified data. The ADS8320-HT is a high-temperature variant, likely lead-free, but this is not confirmed.
