General Description
The G1212 is a rail-to-rail input and output sin-
gle-supply amplifiers. This high output current makes
these amplifiers excellent for driving either resistive or
capacitive loads. AC performance is very good with
3.0MHz bandwidth.
The very low input bias currents enable the G1212 to
be used for integrators and diode amplification and
other applications requiring low input bias current. The
supply current is only 700µA per amplifier at 3.0V,
allowing low current applications to control high cur-
rent loads.
Applications include audio amplification for computers,
sound ports, sound cards and set-top boxes. The
G1212 is very stable and capable of driving 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 sin-
gle-supply systems.
Applications
Battery-Powered Instruments
Portable Equipment
Audio Signal Conditioning
