TSL2540 − Application Information

Schematic

Figure 37:

Typical Application Circuit

Note(s):

1. The value of the I²C pull up resistors RPU should be based on the 1.8V bus voltage, system bus speed and trace capacitance.

2. The bulk capacitor can affect the stability of a regulated supply output and should be chosen with the regulator characteristics in

mind.

3. VSS and PGND should be connected to the same solid ground plane as close to the device as possible.
