DESCRIPTION
The LMV751 is a high performance CMOS
operational amplifier intended for applications
requiring low noise and low input offset voltage. It
offers modest bandwidth of 4.5MHz for very low
supply current and is unity gain stable.
The output stage is able to drive high capacitance, up
to 1000pF and source or sink 8mA output current.
It is supplied in the space saving SOT-23-5 Tiny
package.
The LMV751 is designed to meet the demands of
small size, low power, and high performance required
by cellular phones and similar battery operated
portable electronics.
