General Purpose, Low Voltage, Rail-to-Rail Output Operational Amplifiers

General Purpose, Low Voltage, Rail-to-Rail Output Operational Amplifiers - LMV321-N
 

Recommended alternative parts

  • LMV301  -  Higher Performance, Lower Supply Voltage
  • LMV651  -  Lower Current Consumption( 0.1mA), Higher Bandwidth(12Mhz), Lower Input Offset (Vos)(0.9mV), Lower I

Description

The LMV358-N and LMV324-N are low-voltage (2.7 V to 5.5 V) versions of the dual and quad commodity op amps LM358 and LM324 (5 V to 30 V). The LMV321-N is the single channel version. The LMV321-N, LMV358-N, and LMV324-N are the most cost-effective solutions for applications where low-voltage operation, space efficiency, and low price are important. They offer specifications that meet or exceed the familiar LM358 and LM324. The LMV321-N, LMV358-N, and LMV324-N have rail-to-rail output swing capability and the input common-mode voltage range includes ground. They all exhibit excellent speed to power ratio, achieving 1 MHz of bandwidth and 1-V/µs slew rate with low supply current.

The LMV321-N is available in the space saving 5-Pin SC70, which is approximately half the size of the 5-Pin SOT23. The small package saves space on PC boards and enables the design of small portable electronic devices. It also allows the designer to place the device closer to the signal source to reduce noise pickup and increase signal integrity.

The chips are built with Texas Instruments's advanced submicron silicon-gate BiCMOS process. The LMV321-N/LMV358-N/LMV324-N have bipolar input and output stages for improved noise performance and higher output current drive.
