bandgap voltage and bias generation

The ONET3301PA limiting amplifier is supplied by a single 3.3-V

±10% supply voltage connected to the VCC

and VCCO pins. This voltage is referred to ground (GND).

An on-chip bandgap voltage circuitry generates a supply voltage independent reference from which all other

internally required voltages and bias currents are derived.

package

For the ONET3301PA, a small footprint 3 mm

× 3 mm 16-pin QFN package is used with a lead pitch of 0,5 mm.

The pin out is shown in Figure 2.
