Note: This voltage should be applied across VDD and V5. The following voltages are output

to the V1, V2, V3A (V3B) and V4 pins:

• 1/4 bias

V1 = {VDD–(VDD–V5)/4} ±0.15V

V2 = V3B= {VDD–(VDD–V5)/2} ±0.15V

V4 = {VDD–3 ¥ (VDD–V5)/4 } ±0.15V

• 1/5 bias

V1 = {VDD–(VDD–V5)/5} ±0.15V

V2 = {VDD–2 ¥ (VDD–V5)/5} ±0.15V

V3A = V3B= {VDD–3 ¥ (VDD–V5)/5} ±0.15V

V4 = {VDD–4 ¥ (VDD–V5)/5} ±0.15V

The voltages at the V1, V2, V3A (V3B), V4 and V5 pins should satisfy

VDD>V1>V2>V3A(V3B)>V4>V5.

* Do not apply short–circuiting across output pins and across an output pin and an

input/output pin or the power supply pin in the output mode.
