Notes:
1. The negative bias voltages specified are generated on-chip using an internal oscillator. Two external capacitors, C
NB
and C
SUB
, of
47nF are required for this purpose.
2. The characteristics are measured using two external reference resistors R
and R
of value 33k
wired from pins R
to
ground. For the ZNBR4000, resistor R
sets the drain current of FETs 1 and 2, resistor R
sets the drain current of FETs 3 and 4.
For the ZNBR6000, resistor R
CAL1
sets the drain current of FETs 1 and 4, resistor R
CAL2
sets the drain current of FETs 2, 3, 5 and 6.
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. C
G
, 4.7nF, are connected between
gate outputs and ground, C
D
, 10nF, are connected between drain outputs and ground.
