Analog Outputs

The SPT5240 provides differential current outputs which

provide an output level based on the value of RSET at

maximum output code (see Figure 3). The required value of

RSET may be calculated using the formulas:

LSB = IFS/1023

Then:

RSET = 1.111 – (1000 • LSB)

4 • LSB

Where IFS is the desired full-scale current output.

Each output requires a minimum 5Ω load to analog ground.

The typical circuit utilizes 50Ω loads to develop voltage for

the output transformer (refer to EB5240 data sheet).

X indicates either data state.
