Global Mixed-mode Technology Inc.
Rail-to-Rail I/O OP Amp
General Description
G1212
Features
ꢀSingle-Supply Operation: 2.0V to 5.5V
ꢀLow Supply Current: 700 µA
ꢀWide Bandwidth: 3 MHz
ꢀSlew Rate: 1 V/µs
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.
ꢀNo Phase Reversal
ꢀUnity Gain Stable
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.
ꢀSmall, 5-Pin SOT23-5 Package available
Applications
ꢀBattery-Powered Instruments
ꢀPortable Equipment
ꢀAudio Signal Conditioning
ꢀMultimedia Audio
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.
