LM224ADT  

OP Amps, Buffer Amps ICs

The LM224ADT is a low-power, precision, quad operational amplifier (op-amp) manufactured by STMicroelectronics. It is designed to provide high performance in a wide range of applications, including industrial, medical, and consumer electronics.

Description:

The LM224ADT is a 14-pin DIP (Dual In-line Package) or SOIC (Small Outline Integrated Circuit) package that contains four independent operational amplifiers. Each op-amp within the LM224ADT is designed to operate with a wide range of input signals and provide high accuracy and low noise performance.

Features:

1. Low power consumption: The LM224ADT operates with a supply voltage range of ±2.5V to ±18V and has a low quiescent current of 2.2mA per amplifier, making it suitable for battery-powered applications.
2. Precision performance: The op-amps within the LM224ADT have a high input impedance, low input offset voltage (typically 1mV), and low input bias current (typically 10pA), ensuring accurate amplification of input signals.
3. Wide bandwidth: Each op-amp in the LM224ADT has a small-signal bandwidth of 1MHz, allowing it to handle high-frequency signals with minimal distortion.
4. Rail-to-rail input and output: The LM224ADT can operate with input signals that go all the way to the supply rails, and its output can also swing rail-to-rail, making it suitable for applications requiring a wide input and output voltage range.
5. Short-circuit protection: The LM224ADT features internal protection against output short circuits, which helps prevent damage to the device in case of accidental short circuits.

Applications:

1. Audio amplification: The LM224ADT's low noise and high accuracy make it suitable for audio signal amplification in applications such as headphones, speakers, and audio mixers.
2. Medical instrumentation: The precision and low power consumption of the LM224ADT make it an ideal choice for medical equipment, such as blood pressure monitors, pulse oximeters, and electrocardiogram (ECG) machines.
3. Industrial control systems: The LM224ADT can be used in industrial control systems for signal conditioning, amplification, and filtering of sensor inputs.
4. Battery-powered devices: Due to its low power consumption, the LM224ADT is suitable for use in battery-powered devices, such as portable data acquisition systems, handheld instruments, and wearable electronics.
5. Consumer electronics: The LM224ADT can be used in various consumer electronics applications, including audio equipment, home automation systems, and portable gaming devices.

In summary, the LM224ADT is a versatile, low-power, and precision quad operational amplifier that can be used in a wide range of applications, from audio amplification to medical instrumentation and industrial control systems. Its features, such as low power consumption, precision performance, and rail-to-rail input and output, make it a popular choice for designers looking for a reliable and high-performance op-amp solution.
