NOTES

ENC differentially.

× referenced to 2.0 V crossing; digital output levels referenced to 0.8 V and 2.0 V crossings; all outputs with 10 pF load.

°C specification is valid from 25°C to 85°C. The Full temperature specification includes cold temperature extreme and

covers the entire range, –40

°C to +85°C.

Specifications subject to change without notice.
