175°C, Wide Supply 2.
5V Precision Voltage
Reference DESCRIPTION
The LT®6654BX is a 2.
5V precision voltage reference that is rated for operation up to 175°C junction temperature.
The LT6654BX operates from voltages up to 36V and is fully specified from –40°C to 175°C.
A buffered output ensures both sourcing and sinking output current, with low output impedance and precise load regulation.
These features, in combination, make the LT6654BX well positioned for high temperature environment applications.
Low thermal hysteresis ensures high accuracy and 1.
5ppmP-P noise minimizes measurement uncertainty.
Since the LT6654BX can also sink current, it can operate as a low power negative voltage reference with the same precision as a positive reference.
The typical performance characteristics and the application information of the standard LT6654BH applies to the LT6654BX as well.
See the LT6654 data sheet for more information.
The LT6654BX reference is offered in an 8-lead MSOP package.
