RA and RB currents not included. 3. VSUPPLY =20V;RA and RB =10kΩ,f ≅ 10kHz nominal; can be extended 1000 to 1. See Figures 5A and 5B. 4. 82k Ω connected between pins 11 and 12, Triangle Duty Cycle set at 50%. (Use RA and RB.) 5. Figure 1, pins 7 and 8 connected, VSUPPLY = ±10V. See Typical Curves for T.C. vs VSUPPLY. 6. Not tested, typical value for design purposes only. Electrical Specifications VSUPPLY = ±10V or +20V, TA =25 oC, R L =10kΩ, Test Circuit Unless Otherwise Specified (Continued) PARAMETER SYMBOL TEST CONDITIONS ICL8038CC ICL8038BC ICL8038AC UNITS MIN TYP MAX MIN TYP MAX MIN TYP MAX Test Conditions PARAMETER RA RB RL CSW1 MEASURE Supply Current 10k Ω 10k Ω 10k Ω 3.3nF Closed Current Into Pin 6 Sweep FM Range (Note 7) 10k Ω 10k Ω 10k Ω 3.3nF Open Frequency at Pin 9 Frequency Drift with Temperature 10k Ω 10k Ω 10k Ω 3.3nF Closed Frequency at Pin 3 Frequency Drift with Supply Voltage (Note 8) 10k Ω 10k Ω 10k Ω 3.3nF Closed Frequency at Pin 9 Output Amplitude (Note 10) Sine 10k Ω 10k Ω 10k Ω 3.3nF Closed Pk-Pk Output at Pin 2 Triangle 10k Ω 10k Ω 10k Ω 3.3nF Closed Pk-Pk Output at Pin 3 Leakage Current (Off) (Note 9) 10k Ω 10k Ω 3.3nF Closed Current into Pin 9 Saturation Voltage (On) (Note 9) 10k Ω 10k Ω 3.3nF Closed Output (Low) at Pin 9 Rise and Fall Times (Note 11) 10k Ω 10k Ω 4.7k Ω 3.3nF Closed Waveform at Pin 9 Duty Cycle Adjust (Note 11) Max 50k Ω ~1.6k Ω 10k Ω 3.3nF Closed Waveform at Pin 9 Min ~25k Ω 50k Ω 10k Ω 3.3nF Closed Waveform at Pin 9 Triangle Waveform Linearity 10k Ω 10k Ω 10k Ω 3.3nF Closed Waveform at Pin 3 Total Harmonic Distortion 10k Ω 10k Ω 10k Ω 3.3nF Closed Waveform at Pin 2 NOTES: 7. The hi and lo frequencies can be obtained by connecting pin 8 to pin 7 (fHI) and then connecting pin 8 to pin 6 (fLO). Otherwise apply Sweep Voltageat pin8(2/3 VSUPPLY +2V) ≤ VSWEEP ≤ VSUPPLY where VSUPPLY is the total supply voltage. In Figure 5B, pin 8 should vary between 5.3V and 10V with respect to ground. 8. 10V ≤ V+ ≤ 30V, or ±5V ≤ VSUPPLY ≤±15V. 9. Oscillation can be halted by forcing pin 10 to +5V or -5V. 10. Output Amplitude is tested under static conditions by forcing pin 10 to 5V then to -5V. 11. Not tested; for design purposes only. ICL8038 |
