Exposure to such conditions may adversely impact product reliability and result in failures not covered by warranty. NOTE: 9. θ JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details. Analog Characteristics Operating Conditions over recommended industrial (2.7V) unless otherwise specified.

Coefficient ±20 ppm/°C CH/CL/CW Potentiometer Capacitances See Macro model 10/10/25 pF NOTES: 10. Absolute linearity is utilized to determine actual wiper voltage versus expected voltage as determined by wiper position when used as a potentiometer. 11. Relative linearity is utilized to determine the actual change in voltage between two successive tap positions when used as a potentiometer. It is a measure of the error in step size. 12. MI = RTOT / 255 or (RH - RL)/255, single pot 13. During power-up VCC > VH, VL, and VW. 14. n = 0, 1, 2,....,255; m = 0, 1, 2,...., 254. X9279 |
