(*1)

Supply an equal voltage to both DVDD and AVDD.

(*2)

A volume control resistor of approx. 500 W is recommendable for adjusting the output

current. When a DA converter analog output is terminated with a 37.5 W load, Riadj

= approx. 192 W.

(*3)

Indicates the value when Riadj = 385 W (typical value).
