Data Sheet

5V Operation

5 Electrical Characteristics

5.1 5V Operation

VCC = 5V, GND = 0V, SHDN = VCC, SHDM = GND, RIN = RF = 10k

Ω (AS1702), TAMB = +25°C, CBIAS = 0.1µF, no load.

Typical values are at TAMB = +25°C (unless otherwise specified). All specifications are 100% tested at TAMB = +25°C

(unless otherwise specified). Specifications over temperature (TAMB = TMIN to TMAX) are guaranteed by design, not

production tested.

Supply Current 1

1. Quiescent power supply current is specified and tested with no load. Quiescent power supply current depends

on the offset voltage when a practical load is connected to the amplifier. Guaranteed by design.
