Note 4:
When these pin voltages are taken below V ranges is the worst-case deviation of the last code transition from ideal EE or above VCC, they will be clamped by internal diodes. This product can handle input currents and includes the effect of offset error. of up to 100mA below V
Note 13:
All specifications in dB are referred to a full-scale input in the EE or above VCC without latchup.
Note 5:
When these pin voltages are taken below GND or above V relevant SoftSpan input range, except for crosstalk, which is referred to DD or OV the crosstalk injection signal amplitude. DD, they will be clamped by internal diodes. This product can handle currents of up to 100mA below GND or above V
Note 14:
Temperature coefficient is calculated by dividing the maximum DD or OVDD without latchup. change in output voltage by the specified temperature range.
