Electrical Characteristics (continued)

All specifications are for AVDD = 1.8 V, DVDD = 1.8 V, VREF = 5 V, and fDATA = 2.5 MSPS, unless otherwise noted.

All minimum and maximum specifications are for TA = –40°C to +125°C, unless otherwise noted.

All typical values are at TA = 25°C.

UNIT

(4)

All specifications expressed in decibels (dB) refer to the full-scale input (FSR) and are tested with an input signal 0.1 dB below full-scale,

unless otherwise specified.

(5)

Calculated on the first nine harmonics of the input frequency.

(6)

As per the JESD8-7A standard. Specified by design; not production tested.
