The l denotes the specifications which apply over the full operating temperature

range, otherwise specifications are at TA = 25°C. AVDD18, DVDD18 = 1.71V to 1.89V, AVDD33, DVDD33 = 3.135V to 3.465V, SVDD = 1.71V

to 3.465V, RFSADJ = 500Ω, output load 50Ω double terminated, unless otherwise specified.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device

reliability and lifetime.

Note 2: All voltages are with respect to GND.

Note 3: Guaranteed by design and not production tested.

Note 4: Digital inputs at 0V or SVDD.

Note 5: Latency is the delay from a transition on DCKIP/N until the CKP/N

transition which causes the sample on DAP/N or DBP/N to appear at the

DAC output IOUTP/N, as measured in DAC sample clock (CKP/N) cycles.
