描述 Description

LMV321 (single channel) is a rail-to-rail input, output voltage feedback, low power consumption operational amplifier. It has wide input common mode voltage and output swing. The minimum working voltage can be up to 2.1V, and the maximum working voltage is recommended to be 5.5V. Used as power amplifier in all kinds of pocket or portable stereo

radio recorders.

LMV321 has the following characteristics:Can provide 1MHz gain bandwidth product. It has an extremely low input bias current (about 10pA TYP) and can be used for integration,photo diode amplifiers and piezoelectric sensors. The Rail to Rail input and output buffers are also used for specific IC designs in single power systems. Applications of this series of amplifiers include safety monitoring, portable devices, batteries and power supplies, supply control, signal processing and interfaces in low power sensor systems.

The LMV321 single is available in Green SC70-5 and SOT23-5 packages. The LMV358 dual is available in Green SOP-8 and

TSSOP-8 packages.The LMV324 Quad is available in Green SOP- 14 and TSSOP-14 packages.
