(1)
Measured differential across IOUTA1 and IOUTA2 or IOUTB1 and IOUTB2 with 25
each to AVDD.
(2)
Nominal full-scale current, IOUTFS , equals 32× the IBIAS current.
(3)
The upper 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 DAC5687 device. The lower limit of the output compliance is determined by the load resistors and
full-scale output current. Exceeding the limits adversely affects distortion performance and integral nonlinearity.
(4)
Use an external buffer amplifier with high impedance input to drive any external load.
