External resistance (Rext) connection
For Rext, use a 1/2 W or larger metal film or wire-wound type resistor with good
temperature coefficient and small aging effect.
To minimize the influence of noise on the output, use a two-core shielded wire or a
twisted-pair wire to connect the control terminals and Rext. Make the wires as short
as possible. Susceptibility to the effects of noise increases as the wires get longer.
When wires are long, proper operation may be hindered even if a cable with anti-
noise measures is used.
When using a shielded cable, connect the shield to the - (neg.) output terminal.
Pins 21 and 22 of the J1 connector are used.
