NOTES

11The max/min specifications are guaranteed over this range. The max/min values are typical over 3.0 V to 3.6 V.

12Temperature range T

MIN to TMAX: 0°C to +70°C.

13Guaranteed by characterization.

14All digital input pins except pins

RESET, OSD0 and CLOCK.

15Excluding all digital input pins except pins

RESET, OSD0 and CLOCK.

16Full drive into 75

Ω load.

17DACs can output 35 mA typically at 3.3 V (R

SET = 150 Ω and RL = 75 Ω), optimum performance obtained at 18 mA DAC current (R SET = 300 Ω and RL = 150 Ω).

18Minimum drive current (used with buffered/scaled output load).

19Power measurements are taken with Clock Frequency = 27 MHz. Max T

J = 110°C.

10I

DAC is the total current (min corresponds to 5 mA output per DAC, max corresponds to 38 mA output per DAC) to drive all three DACs. Turning off individual

DACs reduces IDAC correspondingly.

11I

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

Specifications subject to change without notice.

REF = 1.235 V, RSET = 300
