NSC LMV751M5, LMV751MWC Datasheet

LMV751 Low Noise, Low Vos, Single Op Amp

General Description

The LMV751 is a high performance CMOS operational amplifier intended for applications requiring low noise and low input offset voltage.It offers modestbandwidth 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.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.Electrical specifications do not apply when operating the device beyond its rated operating conditions.

Note 2: All limits are guaranteed by testing or statistical analysis Note 3: Human body model, 1.5kΩ in series with 100pF. Machine model, 200Ω in series with 1000pF. Note 4: The maximum power dissipation is a function of T
