WAFER TEST LIMITS

For proper operation, a 1 μF capacitor is required between the output pins and the GND pin of the REF19x. Electrical tests and wafer

probe to the limits are shown in

Table 23

. Due to variations in assembly methods and normal yield loss, yield after packaging is not guaranteed for standard product dice.

Consult factory to negotiate specifications based on dice lot qualifications through sample lot assembly and testing.
