Unit

Total Power Dissipation

Total power dissipation of 2 V and 1 V supplies

DAC DC SPECIFICATIONS

Nominal supplies with DAC output full-scale current (I_OUTFS) = 26 mA, unless otherwise noted. ADC setup in 6 GSPS, full bandwidth mode (all

digital downconverters bypassed). For the minimum and maximum values, T_J= −40°C to +120°C, and for the typical values, T_A= 25°C, which

corresponds to T_J= 80°C, unless otherwise noted.

Bias each output to GND across a shunt inductor

DC Coupling

Bias each output to a negative voltage rail across a 25

Ω to 200 Ω resistor, selected such that VCM_OUT= 0 V,

VCM_OUT= 0.3 V is with a 25 Ω resistor to GND and

I_OUTFS= 20 mA

Differential Resistance

For dc-coupled applications, the maximum full-scale output current is limited by the maximum VCM_OUTspecification.

The actual measured full-scale power is frequency dependent due to DAC sinc response, impedance mismatch loss, and balun insertion loss.
