SLAS371D – SEPTEMBER 2002 – REVISED AUGUST 2004
Table 15. PDN Bit Operation
PDN
Value
Description
0
Internal reference is powered at all times
1
Internal reference is powered down between conversions.
(default)
Note that the PDN bit, in concert with the INT bit, creates a few possibilities for reference behavior. These are
detailed in Table 16.

0
Internal reference used, always powered up
1
Internal reference used, powers up during conversions
and then powers down.
Bit 0 — RFV
Reference Voltage Control. This bit selects the internal reference voltage, either 1.2 V or 2.5 V. The default value
is 1.2 V. This bit is the same whether reading or writing.
