Specifications subject to change without notice.
Measured using internal R
Guaranteed and not tested.
Gain TC is measured from +25 C to T
Absolute Temperature Coefficient is approximately +50 ppm/ C.
From 50% of digital input to 90% of final analog output current. V
WR, LDAC = 0 V; DB0–DB7 = 0 V to V
Settling time is measured from 50% of the digital input change to where the output settles within 1/2 LSB of full scale.
See Timing Diagram.
These limits apply for the commercial and industrial grade products.
These limits also apply as typical values for V
