LSB means Least Significant Bit. With a ± 10 V input, one LSB is 305 µV.
Typical rms noise at worst case transitions and temperatures.
Measured with fixed resistors as shown in Figures 11, 12 and 13. Adjustable to zero. Tested at room temperature.
Full-Scale Error is expressed as the % difference between the actual full-scale code transition voltage and the ideal full scale transition voltage, and includes the effect of offset
External 2.5 V reference connected to REF.
f
All specifications in dB are referred to a full scale ± 10 V input.
Full-Power Bandwidth is defined as full-scale input frequency at which Signal-to-(Noise+Distortion) degrades to 60 dB, or 10 bits of accuracy.
Recovers to specified performance after a 2 × F
error. For bipolar input ranges, the Full-Scale Error is the worst case of either the –Full Scale or +Full Scale code transition voltage errors. For unipolar input ranges, Full-Scale
Error is with respect to the +Full-Scale code transition voltage.
