6. Calculated from worst case RREF: IZSE (in LSBs) = (RREF x ILKG x 4096)/VREF.

7. Absolute temperature coefficient is less than 300 ppm/°C.

8. IOUT, Load = 100 Ω. CEXT = 13 pF, digital input = 0V to VDD or VDD to 0V. Extrapolated to 1/2 LSB: ts = propagation delay (tPD) +

9t, where t equals measured time constant of the final RC decay.

9. All digital inputs = 0V.

10.VREF = 0V, all digital inputs = 0V to VDD or VDD to 0V.

11. Calculations from en = sqrt(4K* T*R*B) where:

K = Boltzmann constant ((J/K) = 1.38E-23 Juoles/Kelvin), R = resistance Ω (10K for the 8143)

T = resistor temperature (Kelvin 26C ~ 300K), R = bandwidth, Hz

12.Digital input are CMOS gates; IIN typically 1 nA at +25 °C.

13.Measured from active strobe edge (STB) to new data output at SRO; CL = 50 pF.

14.Minimum low time pulsewidth for STB1, STB2, and STB4, and minimum high time pulsewidth for STB3.
