NOTES:
1.
The negative bias voltages specified are generated on-chip using an internal oscillator. Two external capacitors,
CNB and CSUB, of 47nF are required for this purpose.
2.
The characteristics are measured using an external reference resistor RCAL of value 33k wired from pins RCAL
to ground.
3.
Noise voltage is not measured in production.
4.
Noise voltage measurement is made with FETs and gate and drain capacitors in place on all
outputs.CG,4.7nF,are connected between gate output and ground,CD,10nF,are connected between drain
outputs and ground.
5.
These parameters are linearly related to Vcc.
6.
These parameters are measured using Test Circuit 1
