Application Information

9.1

Schematic

Figure 57 shows a typical application circuit. Digital and analog grounds should be routed separately

onto the printed circuit board and must be connected together near the device. The die attach pad (no.

17) of the QFN16 must be connected to analog ground VSSA. Without this contact it can lead to errors

of the sensor.

Typical Application Circuit

Please make sure that all specified components within the application circuit work according to their

operating range and to the parameters in the data sheet. For example, voltage regulators (workspace

load current, separated analog and digital or decoupled power supplies based on a common regulator)

need special treatment to avoid noise or deviations during operation.

9.2

External Components

The AS73211 and its external components for references and/or power supply (e.g. reference resistor

REXT) should be placed on the same PCB side.
