gradient =–0.1% C>
When the intermediate resistor values (D4, D3, D2, D1,
D0) = (1, 0, 0, 0) are selected from the electronic vol-
ume, the following is given by expression B-1 since
15 and V
If you select 5 A for the current conducted to Ra' and
When using external resistors (When using vari-
able resistors in stead of the built-in V
adjusting resistors)
Adding external variable resistors to the above mentioned
external resistors allows you to select an LCD drive volt-
age V
too, using the electronic volume function permits you to
control an LCD voltage through the command and, thus,
adjust contrast of the LCD display.
You can determine the V
expression when fine adjustment of Ra' and Rb' is done
