NOTES:
1. Internal Power Dissipation may limit Output Current below 160mA.
2. 3V Step, 50% duty cycle, 200ns period.
3. 3V Step, measured from 50% of input to ±1% of reference value at 50ns.
4. VHIGH = 2.6V, VLOW = 2.3V, VCC = 9V to 10V, VEE = -4.2V to -5.2V
5. Minimum/maximum output swing will vary with supply voltage.
6. 5V Step, 50% duty cycle, 100ns period.
7. For VHIGH = 0V to 5V, For VLOW = 0V to 5V, Fullscale = 5V, 0.1% = 5mV.
8. For VHIGH = -1.5V to 7V, For VLOW = -2.0V to 6.5V, Fullscale = 8.5V, 0.1% = 8.5mV
9. Shorting the output to a voltage outside the specified range may damage the output.
10. VCC = 9.9V, VEE = -5.1V.
11. VHIGH to VLOW Interaction is measured as the change in VOUT (the active channel) due to a change in the inactive channel. VHIGH
Interaction at 250mV is measured as the deviation from 1V as VLOW is changed from 0V to 750mV (Referred to VOUT). VLow Interaction at
250mV is measured as the deviation from 0V as VHIGH is changed from 1V to 250mV (Referred to VOUT).
12. 0V to 3V Step, 200ns period, Pulse Width is varied from 5ns to 195ns.
13. End Point Gain Deviation is the percent deviation of Gain calculated in 0.5V steps at the extremes of output voltage range. For example in the
VHIGH range 5.7V to 6.7V, Gain is calculated for VHIGH = 5.7V to 6.2V (Note 15) and VHIGH = 6.2V to 6.7V (Note 15) the difference in gain is
calculated and converted to a percentage. The voltage ranges tested are: VHIGH = -1.5V to -0.5V (Note 15) and 5.7V to 6.7V (Note 15), VLOW
= -2.0V to -1.0V (Note 15) and 5.5V to 6.5V (Note 15).
14. VHIGH End Point Gain Error is the VOUT absolute error from ideal for a VHIGH change from 6.7V to 7.0V (Note 15).
15. Input voltages VHIGH and VLOW are corrected for Offset Voltage and 7.5V Full Scale Gain Error.
16. Minimum Pulse Width is measured 50% to 50% of specified amplitude with pulse peak at 90% of amplitude.
17. Test is performed into a 50Ω load with a 3V step. Measurement is made from the 50% of input to 50% of output.
18. Dynamic Output Resistance will be higher (typical 48.5Ω) than DC Output Resistance.
