General-Purpose I/O 1. Register controllable using SPI.
General-Purpose I/O 2. Register controllable using SPI.
General-Purpose I/O 3. Register controllable using SPI.
Ground. Ground reference for analog and digital circuitry.
Differential Reference Positive Input. REFP must be more positive than REFN. Connect REFP to a voltage
between AVDD and GND.
Differential Reference Negative Input. REFN must be more negative than REFP. Connect REFN to a
voltage between AVDD and GND.
Negative Fully Differential Analog Input
Positive Fully Differential Analog Input
Analog Supply Voltage. Connect a supply voltage between +2.7V and +3.6V with respect to GND.
Digital Supply Voltage. Connect a digital supply voltage between +1.7V and +3.6V with respect to GND.
Active-Low, Chip-Select Logic Input
Serial-Data Input. Data present at DIN is shifted to the device’s internal registers at the rising edge of
the serial clock at SCLK, when the device is accessed for an internal register write or for a command
operation.
Data Ready Output/Serial-Data Output. This output serves a dual function. In addition to the serial-data
output function, the RDY/DOUT also indicates that the data is ready when the RDY is logic-low. RDY/
DOUT changes on the falling edge of SCLK.
Serial-Clock Input. Apply an external serial clock to SCLK.
External Clock Signal Input. When external clock mode is selected (EXTCLK = 1), provide a 2.4576MHz
or 2.048MHz clock signal at CLK. Other frequencies can be used, but the data rate and digital filter notch
frequencies scale accordingly.
General-Purpose I/O 4. Register controllable using SPI.
