NOTES

1Test Method complies with EIAJ Standard CP-307.

2The signal-to-noise measurement includes noise contributed by the SE5534A op amp used in the test fixture but does not include the noise contributed by the low

pass filter used in the test fixture.

Specifications in boldface are tested on all production units at final electrical test.

Specifications subject to change without notice.
