Refer to the PDF data sheet for device specific package drawings
The device includes a precision 2.5-V bandgap reference with a maximum temperature drift of 10 ppm/°C. The internal reference is in power-down mode by default.
The internal reference voltage is available at the VREFIO pin and can source up to 5 mA. To filter noise, place a minimum 150-nF capacitor between the reference output and ground.
External reference operation is also supported. The external reference is applied to the VREFIO pin. If using an external reference, power down the internal reference.
