Functions

• Dual - amplifier structure: The LM258DT contains two independent, high - gain, 
• internally frequency - compensated operational amplifier circuits,
•  which can work independently to realize the amplification function of different signals.
• Wide power supply voltage range: It can operate with a single power supply voltage ranging from 3V to 30V.
•  It can also work in a dual - power - supply mode, such as ±12V, ±3V, ±5V, ±9V, etc., which is suitable for various power supply systems.
• High DC voltage gain: The DC voltage gain is as high as 100 dB, 
• which can effectively amplify weak input signals to meet the requirements of different application scenarios for signal amplification.
• Wide bandwidth: The bandwidth under unity gain is 1.1 MHz (temperature - compensated), 
• which can well handle signals in a relatively wide frequency range and ensure the fidelity of signal amplification.
• Low - power consumption characteristics: The power supply current of each channel is very low and basically independent of the power supply voltage, 
• which helps to save energy and is suitable for applications where power consumption needs to be considered. In addition, 
• it has a low input bias current of 20 nA (temperature - compensated), a low input offset voltage of 2 mV, 
• and a low input offset current of 2 nA, which can improve the accuracy and stability of the circuit.
• Wide input voltage range: The input common - mode voltage range includes the negative rail, 
• and the differential input voltage range is equal to the power supply voltage, which can adapt to various input signal levels.
• Large output voltage swing: The output voltage swing range is from 0V to (VCC ± 1.5 V), 
• which can provide a large - amplitude output signal to drive subsequent load circuits.

Applications

• Transducer amplifier: It can be used to amplify the weak signals output by transducers, 
• such as those from pressure, temperature, and displacement transducers, 
• to convert non - electrical signals into electrical signals for subsequent processing and measurement.
• DC gain block: It is often used in DC amplification circuits to provide a stable DC gain and is suitable for applications that require accurate DC signal amplification,
• such as power supply voltage regulation and sensor signal processing.
• General - purpose operational amplifier circuit: It can be used to build various traditional operational amplifier circuits, such as inverting amplifiers,
•  non - inverting amplifiers, integrators, differentiators, etc. These circuits are widely used in signal processing, control systems, and measurement circuits3.
• Interface circuit: For example, it can provide the standard +5V power supply required by the logic system and realize the interface between different voltage levels and signal types, 
• facilitating the connection and communication between digital and analog circuits.
• Audio amplification: In audio equipment, it can be used for pre - amplification and 
• power amplification of audio signals to improve the volume and quality of audio signals.
• Instrumentation and measurement: It is used in instruments and meters, such as oscilloscopes, voltmeters, 
• and ammeters, to amplify and process measured signals to improve the accuracy and sensitivity of measurements.
