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 RLOAD at IOUT1 and IOUT2, fCLK = 50 MSPS and fOUT = 20 MHz.
