Data Sheet - Electrical Characteristics

6 Electrical Characteristics

All specifications are 100% tested at TAMB = +25ºC.

5V Operation

VDD = 5V, RL = ∞, CBIAS = 0.1µF to GND, SHDN = GND, TAMB +25ºC (unless otherwise specified).

1. Quiescent power supply current is specified and tested without loads on the outputs. Quiescent power supply

current depends on the offset voltage when a practical load is connected to the device.

2. Common-mode bias voltage is the voltage on pin BIAS and is nominally VDD/2.

3. Guaranteed by design.

3V Operation

VDD = 3V, RL = ∞, CBIAS = 0.1µF to GND, SHDN = GND, TAMB +25ºC (unless otherwise specified).
