NOTES
1_{LSB means Least Significant Bit. With a ± 10 V input, one LSB is 305 µV.}
2_{Typical rms noise at worst case transitions and temperatures.}
3_{Measured with fixed resistors as shown in Figures 11, 12 and 13. Adjustable to zero. Tested at room temperature.}
4_{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}
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.
5_{External 2.5 V reference connected to REF.}
6_{fIN = 20 kHz, 0.5 dB down unless otherwise noted.}
7_{All specifications in dB are referred to a full scale ± 10 V input.}
8_{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.}
9_{Recovers to specified performance after a 2 × FS input overvoltage.}
Specifications subject to change without notice.
