Rail-to-Rail Input and Output
General Description
The G1201 is dual 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 3.5MHz
bandwidth, 6.2V/碌s-slew rate and low distortion. All
are guaranteed to operate from a +3 volt single supply
as well as a +5 volt supply.
The very low input bias currents enable the G1201 to
be used for integrators and diode amplification and
other applications requiring low input bias current. Al-
lowing low current applications to control high current
loads.
Applications include audio amplification for computers,
sound ports, sound cards and set-top boxes. The
G1201 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
Multimedia Audio
LCD Driver
ASIC Input or Output Amplifier
Headphone Driver
