DAC DC SPECIFICATIONS

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

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

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

Common-Mode Output Voltage (VCMOUT)

AC Coupling

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 VCMOUT = 0 V,

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

IOUTFS = 20 mA

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

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