1. The product of C4and RT have a direct effect on gain and therefore directly

affect temperature compensation.

2. C4 Range; 20 pF to 0.2 µF.

3. R4 Range; 100 kΩ to 500 kΩ.

4. The IC must be protected from transients above 60 V and reverse battery conditions.

5. Additional filtering on the FREQIN lead may be required.

6. Gauge coil connections to the IC must be kept as short as possible (≤ 3.0 inch)

for best pointer stability.
