3.1 Analog Outputs
The output pins are low-impedance voltage sources.
3.2 Analog Inputs
The non-inverting and inverting inputs are high-
impedance CMOS inputs with low bias currents.
3.3 Power Supply (V_SS and V_DD)
The positive power supply (V_DD) is 1.8V to 5.5V higher
than the negative power supply (V_SS). For normal
operation, the other pins are between V_SS and V_DD.
Typically, these parts are used in a single-(positive)
supply configuration. In this case, V_SS is connected to
ground and V_DD is connected to the supply. V_DD will
need a local bypass capacitor (typically 0.01 µF to
0.1 µF) within 2 mm of the V_DD pin. These parts can
share a bulk capacitor (typically 1 µF to 100 µF) with
other nearby analog parts; it needs to be within 100 mm
of the V_DD pin.
