Power Up and Down Requirements
There are no restrictions on the power-up or power-down conditions of VCC and the voltages applied to the potentiometer pins
provided that VCC is always more positive than or equal to VH, VL, and VW, i.e., VCC ≥ VH, VL, VW. The VCC ramp rate spec is
always in effect.
A.C. Timing
NOTES:
8. Typical values are for TA = +25°C and nominal supply voltage.
9. MI in the A.C. timing diagram refers to the minimum incremental change in the VW output due to a change in the wiper position.
10. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
DC Electrical Specifications
Over recommended operating conditions unless otherwise specified. Boldface limits apply over the
operating temperature range, -40°C to +85°C or 0°C to +70°C.
