Description
Power Supply Pin for the Digital Sigma-Delta (Σ-Δ) Modulator. This pin should be the same voltage as AVDD.
Decoupling capacitors to the ground plane are to be placed as close as possible to this pin.
Digital Σ-Δ Modulator Ground. Ground return path for the Σ-Δ modulator.
Connecting a resistor between this pin and GND sets the charge pump output current. The nominal voltage
bias at the RSET pin is 0.48 V. The relationship between ICP and RSET is
I CP = 23.7
R SET
where:
RSET = 5.1 kΩ.
ICP = 4.65 mA.
The exposed pad must be connected to GND.
