Note 1: INL and DNL are measured with RL referenced to ground. Nonlinearity is measured from the first code that is greater than or
equal to the maximum offset specification to code FF hex (full scale). (See DAC Linearity and Voltage Offset section.)
Note 2: Output settling time is measured from the 50% point of the rising edge of CS to 1/2LSB of the final value of VOUT.
Note 3: Guaranteed by design, not production tested.
Note 4: If LDAC is activated prior to the rising edge of CS, it must remain low for tLDAC or longer after CS goes high.
Note 5: When DOUT is not used. If DOUT is used, fCLK (max) is 4MHz due to SCLK to DOUT propagation delay.
Note 6: Serial data is clocked-out at SCLK’s rising edge (measured from 50% of the clock edge to 20% or 80% of VDD).
Note 7: Serial data is clocked-out at SCLK’s falling edge (measured from 50% of the clock edge to 20% or 80% of VDD).
