NOTES

1The max/min specifications are guaranteed over this range. The max/min values are typical over 4.75 V to 5.25 V.

2Temperature range TMIN to TMAX: 0°C to +70°C.

3Full drive into 37.5␣ Ω doubly terminated load.

4Minimum drive current (used with buffered/scaled output load).

5Power measurements are taken with Clock Frequency = 27 MHz. Max T J = 110°C.

6IDAC is the total current (min corresponds to 5 mA output per DAC, max corresponds to 37 mA output per DAC) to drive all four DACs. Turning off individual

DACs reduces IDAC correspondingly.

7ICCT (Circuit Current) is the continuous current required to drive the device.

8Total DAC current in Sleep Mode.

9Total continuous current during Sleep Mode.

Specifications subject to change without notice.
