† _{Measured at IOUT1 in virtual ground configuration.}
‡ _{Nominal full-scale current IOUTFS equals 32X the IBIAS current.}
§ _{Use an external buffer amplifier with high impedance input to drive any external load.}
¶ _{Reference bandwidth is a function of external cap at COMP1 pin and signal level.}
# _{Measured at fCLK = 50 MSPS and fOUT= 1 MHz.}
|| _{Measured for 50 Ω RLOAD at IOUT1 and IOUT2, fCLK = 50 MSPS and fOUT = 20 MHz.}
