Table 8-1 explains how to compute the total current, I_TOTAL, when the CTSD, along with associated modules, are used. See Section 8.8.14.2 for a similar table for the OA. A "yes" means it must be included in computing I_TOTAL. Here is an example current calculation for CTS16D in rail-to-rail input mode (CTSD16RRI = 1) using the internal reference (CTSD16REFS = 1) and OA0 and OA1 enabled in rail-to-rail input modes, OARRI = 1.

As an example, assume that the application uses the CTS16D in rail-to-rail input mode (CTSD16RRI = 1) with the internal reference (CTSD16REFS = 1) and OA0 and OA1 are enabled in rail-to-rail input modes, OARRI = 1. The total current, I_TOTAL, would be computed as follows:

Equation 1. I_TOTAL = I_CTSD16 + I_CTSD16CLK+ I_CP + I_REFBG + 2 × I_OA

Table 8-1 CTSD16, Current Calculation

USE CASE NAME	USE CASE DETAILS	I_CTSD16	I_CTSD16CLK ⁽¹⁾	I_CP ⁽²⁾	I_REFBG ⁽³⁾	I_REF ⁽⁴⁾
CTSD16		yes	yes	no	yes if CTSD16REFS = 1 no if CTSD16REFS = 0	yes
CTSD16 rail-to-rail inputs	CTSD16RRI = 1	yes	yes	yes	yes if CTSD16REFS = 1 no if CTSD16REFS = 0	yes

(1) Count this only once no matter how many modules use it. OA can also use this when rail-to-rail input is selected.

(2) Count this only once no matter how many modules use it. OA also uses this. This current is listed in Section 8.8.14.1.

(3) Count this only once no matter how many modules use it. DAC can use this as well as internal reference when it is available externally, REFOUT = 1. This current is listed in Section 8.8.12.1.

(4) Count this only once no matter how many modules use it. This current is listed in Section 8.8.14.1. If I_REFBG is used that includes I_REF current.

Section 8.8.11.2 lists the characteristics of the CTSD16 external voltage reference.
