NOTES

1.

LSB means Least Significant Bit. For SP86xx Series, 1LSB = 1.22mV for 5V range, 1 LSB =

2.44mV 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 FS input overvoltage.
