Analog output<br />
The following table and Figure 66 show the relationship between the digital input code and analog output.<br />
800000 (–FS) 000000 (BPZ) 7FFFFF (+FS)<br />
IOUTN [mA] –2.3 –6.2 –10.1<br />
IOUTP [mA] –10.1 –6.2 –2.3<br />
VOUTN [V] –1.725 –4.650 –7.575<br />
VOUTP [V] –7.575 –4.650 –1.725<br />
VOUT [V] –2.821 0 2.821<br />
NOTE: VOUTN is the output of U1, VOUTP is the output of U2, and VOUT is the output of U3 in the<br />
measurement circuit of Figure 36.<br />
