LMV751
Low Noise, Low Vos, Single Op Amp
General Description
The LMV751 is a high performance CMOS operational am-
plifier 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 SOT23-5 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.
