C
T
- 0.0033μF, +/- 30 PPM/C
D1 - 1A, 600 PIV
D2 - 50V, 500mW Zener
Note 1: For 58% Speed Input
T

where
T
MAX
= C
T
(R3+R4)
f
MAX
= maximum speed input frequency
Note 1: The product of C
T
and R
T
have a direct effect on
gain and therefore directly affect temperature compensation
Note 2: C
T
Range; 20pF to .2μF
Note 3: R
T
Range; 100k to 500k
Note 4: The IC must be protected from transients above 60V and
reverse battery conditions
Note 5: Additional filtering on FREQ
