Note 1:
All devices are 100% production tested at T
A
= +25°C. All temperature limits are guaranteed by design.
Note 2:
Guaranteed by PSR test.
Note 3:
Guaranteed by OUT Voltage Error test.
Note 4:
Output voltage is internally clamped not to exceed 12V.
Note 5:
Total OUT voltage error is the sum of gain and offset voltage errors.
