Notes:
1. For 58% Speed Input TMAX ≤ 5.0/fMAX where
TMAX = CCP (R3 + R4)
fMAX = maximum speed input frequency
2. The product of C4 and RT have a direct effect on gain and therefore directly affect temperature compensation.
3. CCP Range; 20 pF to 0.2 mF.
4. RT Range; 100 kW to 500 kW.
5. The Ic must be protected from transients above 60 V and reverse battery conditions.
6. Additional filtering on FREQIN lead may be required.
7. Gauge coil connections to the IC must be kept as short as possible (
≤ 3.0 inch) for best pointer stability.
