General Description
The G1211 is a rail-to-rail input and output sin-
gle-supply amplifiers featuring 100mA output drive
current. This high output current makes these amplifi-
ers excellent for driving either resistive or capacitive
loads. AC performance is very good with 3.0MHz
bandwidth; 4.0V/µs slew rate and low distortion. All
are guaranteed to operate from a +4 to +6 volt single
supply.
The very low input bias currents enable the G1211 to
be used for integrators and diode amplification and
other applications requiring low input bias current. The
100mA high output current and supply current is only
850µA per amplifier at 5 volts, allowing low current
applications to control high current loads.
Applications include audio amplification for computers,
sound ports, sound cards and set-top boxes. The
G1211 is very stable and capable of driving heavy
capacitive loads. The ability to swing rail-to-rail at the
inputs and outputs enables designers to buffer CMOS
ADC/DACs, ASICs or other wide output swing devices
in single-supply systems.
Applications
