1 The max/min specifications are guaranteed over this range. The max/min values are typical over 3.0 V to 3.6 V.
2 Temperature range TMIN to TMAX: 0°C to 70°C.
3 Guaranteed by characterization.
4 All digital input pins except pins RESET, OSD0, and CLOCK.
5 Excluding all digital input pins except pins RESET, OSD0, and CLOCK.
6 Full drive into 75 load.
7 DACs can output 35 mA typically at 3.3 V (RSET = 150 and RL = 75 ), optimum performance obtained at 18 mA DAC current (RSET = 300 and RL = 150 ).
8 Minimum drive current (used with buffered/scaled output load).
9 Power measurements are taken with clock frequency = 27 MHz. Max TJ = 110°C.
10 IDAC 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.
11 ICCT (circuit current) is the continuous current required to drive the device.
