section. These parameters are centered on nominal values, which depend on the mode. In Warp mode, nominal zero error and

nominal gain error are centered around 0 LSB. In Normal and Impulse modes, nominal zero error is +375 LSB, and nominal gain error is +0.273% of FSR. These

specifications are the deviation from these nominal values. These specifications do not include the error contribution from the external reference but do include the

error contribution from the reference buffer, if used.
