Notes:
1. The two Vcc pins are internally connected, only one of the pins needs to be powered for the device to function. See applications section for further
information.
2. ESD sensitive, handling precautions are recommended.
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 package (QFN1633) exposed pad must either be connected to Csub or left open circuit.
5. The characteristics are measured using two external reference resistors RCAL1 and RCAL2 of value 39k , wired from pins RCAL1/2 to ground. Resistor RCAL1
sets the drain current of FETs 1 and 3, resistor RCAL2 sets the drain currents of FETs 2 and 4.
6. Noise voltage measurements are made with FETs and gate and drain capacitors of value 10nF in place. Noise voltages are not measured in production.
