Converter Characteristics

The following specifications apply for RD mode (pin 7 = 0), VCC = 5V, VREF(+) = 5V,and VREF(−) = GND unless otherwise

specified. Boldface limits apply from TMIN to TMAX; all other limits TA = Tj = 25°C.

Sensitivity

(1)

Typicals are at 25°C and represent most likely parametric norm.

(2)

Tested limits are ensured to TI's AOQL (Average Outgoing Quality Level).

(3)

Design limits are specified but not 100% tested. These limits are not used to calculate outgoing quality levels.

(4)

Total unadjusted error includes offset, full-scale, and linearity errors.
