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 TMIN 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␣ load.
17DACs 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 ).
18Minimum drive current (used with buffered/scaled output load).
19Power measurements are taken with Clock Frequency = 27 MHz. Max T J = 110°C.
10IDAC 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.
11ICCT (Circuit Current) is the continuous current required to drive the device.
Specifications subject to change without notice.
