Specifications subject to change without notice.
(1) Measured differentially across IOUT1 and IOUT2 into 50 .
(2) Nominal full-scale current, IOUTFS, 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 DAC5674 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 integral nonlinearity.
(4) Use an external buffer amplifier with high impedance input to drive any external load.
