1B41: Isolated RTD Signal Conditioner
Product Description
The 1B41 is a precision, isolated, RTD signal conditioner that incorporates a circuit design utilizing transformer based isolation and automated surface mount manufacturing technology. It provides an unbeatable combination of versatility and performance in a compact plastic package. Designed for measurement and control applications, it is especially suited for harsh environments with extremely high common mode interference. Unlike expensive solutions that require separate dc/dc converters, each 1B41 generates its own floating current excitation, providing true low cost channel-to channel isolation.

CloseThe model number is a specific version of a generic that can be purchased or sampled.
Status indicates the current lifecycle of the product. This can be one of 4 stages:
- Pre-Release: The model has not been released to general production, but samples may be available.
- Production: The model is currently being produced, and generally available for purchase and sampling.
- Last Time Buy: The model has been scheduled for obsolescence, but may still be purchased for a limited time.
- Obsolete: The specific part is obsolete and no longer available. Other models listed in the table may still be available (if they have a status that is not obsolete).
The package for this IC (i.e. DIP, SOIC, BGA). An Evaluation Board is a board engineered to show the performance of the model, the part is included on the board.
