• Resolution (bits): 12 b
• Sampling Rate (per Second): 25M
• Data Interface: Serial
• Voltage Supply Source: Single Supply
• Voltage - Supply: 1.7 V ~ 3.6 V
• Operating Temperature: -40°C ~ 85°C

This interface is flexible enough to be controlled by either serial
PROMS or PIC mirocontrollers. This provides the user with
an alternative method, other than a full SPI controller, for
programming the device (see the AN-812 Application Note).

If the user chooses not to use the SPI interface, these pins serve
a dual function and are associated with secondary functions
when the CSB is strapped to AVDD during device power-up.
See the SDIO Pin and SCLK Pin sections for details on which
pin-strappable functions are supported on the SPI pins.
