Dual Rail-to-Rail Output Operational Amplifier with Power Select
February 2005
LMV422
Dual Rail-to-Rail Output Operational Amplifier with
Power Select
General Description
The LMV422 dual rail-to-rail output amplifier offers a power
select pin (PS) that allows the user to select one of two
power modes depending on the level of performance de-
sired. This is ideal for AC coupled circuits where the circuit
needs to be kept active to maintain a quiescent charge on
the coupling capacitors with minimum power consumption.
For portable applications, the LMV422 operates in low power
mode consuming only 2 碌A(chǔ) of supply current per channel at
a bandwidth of 27 kHz. This allows the user to reduce the
power consumption of an amplifier while maintaining an
active circuit. For additional bandwidth and output current
drive the amplifier can be switched to full power mode with 8
MHz bandwidth while consuming only 400 碌A(chǔ) per channel.
The LMV422 features a rail-to-rail output voltage swing in
addition to an input common mode range that includes
ground. The LMV422 is designed for closed loop gains of
plus two (or minus one) or greater. The LMV422 is offered in
10-Pin MSOP miniature package to ease the adoption in
applications where board area is at a premium.
