NOTES
1Operating temperature range is as follows: B Version: –40°C to +85°C; typical specifications are at 25؇C
2Guaranteed by Design.
3Applies when REFOUT is sourcing current. The impedance is higher when REFOUT is sinking current.
4Measured with the digital inputs static and equal to 0 V or DVDD.
Specifications subject to change without notice. There is 95% test coverage of the digital circuitry.
