LM348N

The LM348N is a quad operational amplifier (op-amp) manufactured by Texas Instruments. It is designed for a variety of analog signal processing applications, offering versatility and performance in a compact package. Here’s a detailed description of its features and specifications:

General Features:

• Quad Configuration: The LM348N contains four independent, high-gain, frequency-compensated op-amps, making it suitable for multi-channel applications.
• Single Supply Operation: It can operate from a single power supply, typically ranging from +3V to +30V, or dual supplies of ±1.5V to ±15V, providing flexibility in design.
• High Gain: The op-amps have a high open-loop voltage gain, typically around 100,000, which allows for precise amplification of small signals.
• Wide Bandwidth: The LM348N features a unity-gain bandwidth of approximately 1 MHz, making it suitable for a range of frequency applications.
• Low Input Offset Voltage: The input offset voltage is typically around 2 mV, which enhances accuracy in precision applications.
• Low Noise: The device is designed to minimize noise, making it ideal for sensitive audio and instrumentation applications.

Electrical Characteristics:

• Input Impedance: The input impedance is very high, typically around 10^6 ohms, which minimizes the loading effect on the preceding stage.
• Output Drive Capability: The LM348N can drive loads of up to 10 mA, making it capable of interfacing with various components without significant signal degradation.
• Slew Rate: The typical slew rate is about 0.5 V/µs, which defines how quickly the output can respond to rapid changes in the input signal.

Package Information:

• DIP Package: The LM348N is commonly available in a dual in-line package (DIP) format, which is easy to handle and solder onto PCBs. The standard pin configuration allows for straightforward integration into existing designs.

Applications:

The LM348N is widely used in various applications, including:
