NOTES
11Measured using internal RFB A and RFB B. Both DAC digital inputs = 1111 1111 1111.
12Guaranteed and not tested.
13Gain TC is measured from +25°C to TMIN or from +25°C to TMAX.
14Absolute Temperature Coefficient is approximately +50 ppm/°C.
15From 50% of digital input to 90% of final analog output current. VREF A = VREF B = +10 V; OUT A, OUT B load = 100 Ω, CEXT = 13 pF.
16WR, LDAC = 0 V; DB0–DB7 = 0 V to VDD or VDD to 0 V.
17Settling time is measured from 50% of the digital input change to where the output settles within 1/2 LSB of full scale.
18See Timing Diagram.
19These limits apply for the commercial and industrial grade products.
10These limits also apply as typical values for VDD = +12 V with +5 V CMOS logic levels and TA = +25°C.
