(1) Pin numbers represent the PDIP package. The SOIC package pin numbers differ from that of the PDIP package.
(2) If R
L
= R
L
within ±0.05%, output is symmetrical about ground.

(1) Pin numbers represent the PDIP package. The SOIC package pin numbers differ from that of the PDIP package.
(2) For complementary output (operation as negative logic DAC), connect inverting input of op amp to I
O
(pin 2), connect
I
O
(pin 4) to ground.

(1) Pin numbers represent the PDIP package. The SOIC package pin numbers differ from that of the PDIP package.
(2) For complementary output (operation as a negative logic DAC) connect non-inverting input of op am to I
O
(pin 2);
connect I
