Manufacturer profiles associated with Resistor Network / Current Source Array.
Explore company information and manufacturing capabilities, then discuss the scope of your project with a relevant supplier.
Ask for use case, specification boundaries, supplier type, and RFQ preparation information for this product.
The resolution typically ranges from 8 to 16 bits, as listed in the reference parameters. Higher resolution requires more precise resistor matching. Confirm the exact resolution for your specific model with the manufacturer.
The resistor network's matching and tolerance directly influence integral nonlinearity (INL) and differential nonlinearity (DNL). Lower INL and DNL values indicate better linearity. For example, INL is typically ±0.5 to ±2 LSB, and DNL is ±0.5 to ±1 LSB. Verify these parameters for your application.
The reference operating temperature range is -40 to 85 °C. Extended ranges may be available for industrial applications. Always check the datasheet for the specific model to ensure it meets your environmental requirements.
The only standard listed is IEC 60068-2-78 for humidity testing (non-condensing, 5–95% RH). This standard is a reference for verification, not a certification. Confirm compliance with the manufacturer for your specific part.
