(1)

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings

only and functional operation of these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

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 DAC5672 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.
