詳細說明
The LMV931 Single and LMV932 Dual are CMOS low-voltage op-amps which can operate on single-sided power supplies (1.8 V to 5.0 V) with rail-to-rail input and output swing. Both devices come in small state-of-the-art packages and require very low quiescent current making them ideal for battery-operated, portable applications such as notebook computers and hand-held instruments. Rail-to-Rail operation provides improved signal-to-noise performance plus the small packages allow for closer placement to signal sources thereby reducing noise pickup. The single LMV931 is offered in space saving SC70-5 package. The dual LMV932 is in a Micro8. These small packages are very beneficial for crowded PCBs. Further reduction of power consumption is available with the addition of a shutdown function in the LMV981 Single and LMV982 Dual. All other functions and performance are the same. Shutdown is implemented by driving the SHDN pin LOW.
主要特徵
- Single-supply operation from 2.7 V to 5.5 V

常見問題解答
What is LMV932?
The LMV932 is a dual low-voltage, low-power operational amplifier manufactured by Texas Instruments. It is designed for applications requiring precision signal conditioning and amplification in low-voltage and low-power environments, such as portable electronics, sensor interfaces, and battery-powered devices.
How Does LMV932 Work?
The LMV932 operates as a precision operational amplifier with low offset voltage and low input bias current. It amplifies input signals with high accuracy and stability, making it suitable for precise measurement and signal conditioning applications. The amplifier features rail-to-rail input and output, ensuring maximum signal swing even at low supply voltages.
How Many Pins does LMV932 have and What are the Functions of the Pinout Configuration?
The LMV932 is housed in an 8-pin VSSOP (Very Small Outline Package) package. The pinout configuration includes:
- V+: Positive power supply pin.
- V-: Negative power supply pin.
- IN1+: Non-inverting input pin for channel 1.
- IN1-: Inverting input pin for channel 1.
- OUT1: Output pin for channel 1.
- IN2+: Non-inverting input pin for channel 2.
- IN2-: Inverting input pin for channel 2.
- OUT2: Output pin for channel 2.
What are the Pros and Cons of LMV932?
Pros:
- Low Power Consumption: Operates with very low power, making it ideal for battery-operated devices.
- Precision: Provides low offset voltage and low drift, ensuring accurate signal amplification.
- Rail-to-Rail Input and Output: Maximizes signal swing, enhancing dynamic range.
- Low Input Bias Current: Suitable for applications requiring high input impedance.
- Compact Package: The 8-pin VSSOP package is space-efficient, suitable for compact designs.
Cons:
- Limited Bandwidth: May not be suitable for high-frequency applications.
- External Components: May require additional external components for optimal performance in certain applications.
- Package Handling: The 8-pin VSSOP package may be challenging to handle without appropriate equipment.
Are There Any Equivalents/Alternatives to LMV932 for Recommendation?
- The LMV822 from Texas Instruments is a similar dual operational amplifier with low-voltage and low-power features.
- Alternatives to the LMV932 include the MCP6022 from Microchip Technology and the TS922 from STMicroelectronics.
