(1) Measured differentially through 50 Ω to AGND.
(2) Nominal full-scale current, I_OUTFS, equals 32× the IBIAS current.
(3) The lower limit of the output compliance is determined by the CMOS process. Exceeding this limit may result in transistor breakdown,
resulting in reduced reliability of the DAC5662 device. The upper limit of the output compliance is determined by the load resistors and
full-scale output current. Exceeding the upper limit adversely affects distortion performance and intergral nonlinearity.
(4) Use an external buffer amplifier with high impedance input to drive any external load.
