NAME

NO.

DESCRIPTION

IOVDD

Interface power supply

REF-DAC

DAC reference Input

REF-OUT

Internal reference output

RESET

Reset input, active low. A logic low on this pin causes the device to perform a hardware reset.

Serial clock input of the main serial interface. This pin functions as the SPI clock when the SPI/I2C pin is high. This pin

SCLK/SCL

functions as the I2C clock when the SPI/I2C pin is low.

Serial interface data. This pin functions as SDI for the serial peripheral interface (SPI) when the SPI/I2C pin (pin 12) is

SDI/SDA

high. This pin functions as SDA for the I2C interface when the SPI/I2C pin is low.

SDO/A1

SDO for SPI when the SPI/I2C pin is high. Slave address selection A1 for I2C when the SPI/I2C pin is low.

Interface selection pin; digital input. When this pin is tied to IOVDD, the SPI is enabled and the I

2C interface is disabled.

SPI/I2C

When this pin is tied to ground, the SPI is disabled and the I2C interface is enabled.
