LMV751M5/NOPB Datasheet/PDFLMV751M5/NOPB Application Field and Working Principle
The LMV751M5/NOPB is a type of linear op amp from Texas Instruments. Its intended application is instrumentation and its main purpose is to buffer amplifiers, providing unity gain and very low output impedance. It has a high input impedance that allows it to accurately measure and provide data in audio, telecommunication, and medical equipment. The LMV751M5/NOPB features a low offset voltage, low control voltage, high DC gain, and low power supply current.
Input Characteristics
The LMV751M5/NOPB has a very high input impedance of 10^14 ohms and a high slew rate of 8 V/µs. The input stage of the amplifier is an inverting amplifier, meaning that the input signal is inversely related to the output. It has a wide Unity Gain Frequency (UGF) range from DC up to 1 MHz.
Output Characteristics
The output stage of the LMV751M5/NOPB is a buffer stage. This stage is designed to provide low output impedance with a wide load range of up to 10^14 ohms. The output stage is capable of providing a consistent voltage output with a low current draw of only 80 uA.
Power Supply
The LMV751M5/NOPB requires only a single rail power supply of 3V to 30V. It can be used with dual supplies of ±1.5V to ±15V. The device has very low quiescent current of only 80 µA and a very low noise of 7.1 nV/√Hz.
Pricing and Availability
The LMV751M5/NOPB is readily available in the market and can be purchased in a variety of packages. The pricing is also quite reasonable, with prices ranging from $0.30 to $0.50 per unit.
Conclusion
The LMV751M5/NOPB is an ideal choice for instrumentation applications as it provides low output impedance, high input impedance, and low power consumption. Its low noise, low quiescent current, and wide Unity Gain Frequency range make it a versatile and reliable solution for many instrumentation applications.
