• Manufacturer Part Number: IL8190N
• Description: Precision Air-Core Tach/Speedo Driver with Return to Zero
• Manufacturer: IKSEMICON [IK Semicon Co., Ltd]

Speedo Input
GND
Battery
Notes:
1. C2 (> 2000 µ F) is needed if return to zero function is required.
2. The product of C4 and R
3. Ccp Range: 20 pF to 0.2 µ F.
4. R4 Range; 100 k Ω to 500 k Ω .
5. The IC must be protected from transients above 60 V and reverse battery conditions.
6. Additional filtering on the FREQ
7. Gauge coil connections to the IC must be kept as short as possible (≤ 3.0 inch) for best pointer
stability.
