NOTES:
1. All voltages are referenced to ground.
2. Resistor inputs cannot exceed VB - 0.5V in the negative direction.
3. Capacitance values apply at 25
°C.
4. Absolute linearity is used to determine wiper voltage versus expected voltage as determined by wiper
position. Device test limits
±1.6 LSB.
5. Relative linearity is used to determine the change in voltage between successive tap positions. Device
test limits
±0.5 LSB.
6. Typical values are for tA = 25
°C and nominal supply voltage.
7. -3 dB cutoff frequency characteristics for the DS1868 depend on potentiometer total resistance:
DS1868-010; 1 MHz, DS1868-050; 200 kHz; and DS1868-100; 80 kHz.
8. Cout is active regardless of the state of RST .
9. VREF = 1.5 volts.
10. See Figure 9(a), (b), and (c).
11. Noise < -120 dB/ Hz . Reference 1 volt (thermal).
12. Supply current is dependent on clock rate (see Figure 11).
13. See Figure 10.
14. Standby currents apply when RST , LLIC, DQ are in the low-state.
15. When biasing the substrate minimum VB = -3.0V
±10% and maximum V
CC = 3.0V
±10%.
16. Valid at 25
°C only.
