D.C. OPERATING CHARACTERISTICS

(VCC = 5V ±10%, TA = Full Operating Temperature Range unless otherwise stated)

ENDURANCE AND DATA RETENTION

(VCC = 5V ±10%, TA = Full Operating Temperature Range)

Notes: (1) Absolute linearity is utilized to determine actual wiper voltage versus expected voltage = [V(RW(n)(actual))–V(RW(n)(expected))]/MI

V(RW(n)(expected)) = n(V(RH)-V(RL))/99 + V(RL), with n from 0 to 99.

(2) Relative linearity is a measure of the error in step size between taps = [V(RW(n+1))–(V(RW(n)) – MI)]/MI

(3) 1 Ml = Minimum Increment = [V(RH)–V(RL)]/99.

(4) Typical values are for TA = 25°C and nominal supply voltage.

(5) Guaranteed by device characterization.

(6) Ratiometric temperature coefﬁcient = (V(RW)T1(n)–V(RW)T2(n))/[V(RW)T1(n)(T1–T2) x 10

6], with T1 & T2 being 2 temperatures,

and n from 0 to 99.

(7) Measured with wiper at tap position 31, RL grounded, using test circuit.
