6. Calculated from worst case R_REF: I_ZSE (in LSBs) = (R_REF x I_LKG x 4096)/V_REF.
7. Absolute temperature coefficient is less than 300 ppm/^°C.
8. I_OUT, Load = 100 Ω. C_EXT = 13 pF, digital input = 0V to V_DD or V_DD to 0V. Extrapolated to 1/2 LSB: t_s = propagation delay (t_PD) +
9t, where t equals measured time constant of the final RC decay.
9. All digital inputs = 0V.
10.V_REF = 0V, all digital inputs = 0V to V_DD or V_DD to 0V.
11. Calculations from e_n = 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; I_IN typically 1 nA at +25 ^°C.
13.Measured from active strobe edge (STB) to new data output at SRO; C_L = 50 pF.
14.Minimum low time pulsewidth for STB₁, STB₂, and STB₄, and minimum high time pulsewidth for STB₃.
