NOTES

1.

LSB means Least Significant Bit. For SP85XX Series, 1LSB = 2.44mV for

±5V range, 1 LSB =

4.88mV for

±10V range.

2.

All specifications in dB are referred to a full-scale input, either

±10V or ±5V.

3.

For full-scale step input, 12-bit accuracy attained in specified time.

4.

Recovers to specified performance in specified time after 2 x F
