NOTES: (1)

±1/2 LSB = ±0.012% of Full Scale. (2) All grades are monotonic to 12-bits over temperature. (3) Using internal feedback resistor. (4) Applies to I

OUT; All

digital inputs = 0V. (5) Guaranteed by design and not tested. (6) I

OUT Load = 100Ω, CEXT = 13pF, digital input = 0V to VDD or VDD to 0V. Extrapolated to 1/2 LSB:

t

S = propagation delay (tPD) + 9τ where τ = measured time constant of the final RC decay. (7) VREF = +10V, all digital inputs = 0V. (8) Absolute temperature coefficient

is less than

±50ppm/°C. (9) Digital inputs are CMOS gates: I

IN is typically 1nA at +25°C. (10) VREF = 0V, all digital inputs = 0V to VDD or VDD to 0V. (11) All digital

inputs = 0V. (12) Calculated from worst case R

REF: IZSE (in LSBs) = (RREF X ILKG X 4096)/VREF. (13) Calculations from en = √4K TRB where: K = Boltzmann constant,

J/

°K, R = resistance, Ω. T = Resistor temperature, °K, B = bandwidth, Hz. (14) Tested at V

IN = 0V or VDD.
