Notes: 1. To disable FET stages 3 and 6, pin RCAL2 must be set to 3V or above and pin RCALM should be open circuit.

2. The characteristics are measured using up to three external reference resistors, RCAL1, RCAL2 and RCALM,

wired from pins RCAL1/2/M to ground. Resistor RCAL1 sets the drain current of FETs 1 and 4. If RCALM is not

present, resistor RCAL2 sets the drain currents of FETs 2, 3, 5 and 6. If RCALM is present, resistor RCAL2 sets

the drain currents of FETs 2 and 5 and RCALM sets the drain currents of FETs 3 and 6.

3. The negative bias voltages are generated on-chip using an internal oscillator. Two external capacitors,

CNB and CSUB of value 47nF are required for this purpose.

4. The QFN-20(4×4) package exposed pad must either be connected to Csub or left open circuit.

5. Noise voltage measurements are made with FETs and gate and drain capacitors of value 10nF in place.

Noise voltages are not measured in production.

6. ESD sensitive, handling precautions are recommended.
