Product Overview

NE5532DR is a classic dual low-noise operational amplifier launched by Texas Instruments, a core model of the NE5532 series. It adopts an SOIC-8 package (Small Outline Integrated Circuit with 8 pins) and integrates 2 independent high-performance op-amps.

With ultra-low input noise, high slew rate and wide power supply adaptability as its core advantages, this device is designed for weak signal amplification and high-precision signal processing scenarios. It is widely used in audio equipment, industrial sensors, medical instruments and communication systems, serving as a general op-amp solution that balances low-noise performance and industrial-grade reliability, especially excelling in scenarios requiring high signal purity.

Key Features

• Ultra-Low Input Noise: Equivalent input noise voltage is only 5nV/√Hz (typical) at 1kHz and 8nV/√Hz (typical) at 30Hz, which can minimize noise interference during weak signal amplification, adapting to NE5532DR weak signal processing scenarios (such as microphone pre-amplification, sensor small-signal acquisition);
• High Slew Rate: Typical slew rate reaches 9V/μs, enabling fast response to high-speed changing analog signals (such as high-frequency communication signals, pulse sensor signals) and avoiding signal distortion, meeting NE5532DR high-speed signal amplification needs;
• Wide Power Supply Voltage Range: Supports ±3V~±20V dual power supply, with recommended operating voltage of ±5V~±15V, which can adapt to various power supply schemes such as lithium batteries and industrial standard power supplies, reducing NE5532DR cross-scenario power adaptation costs;
• High Common-Mode Rejection Ratio: Typical common-mode rejection ratio (CMRR) is 100dB, which can effectively suppress common-mode interference (such as power noise and electromagnetic interference in industrial environments), improving NE5532DR industrial signal anti-interference capability;
• Comprehensive Protection Mechanism: Built-in input protection diodes (preventing excessive input current) and output short-circuit protection (maximum output short-circuit current of 60mA), avoiding device damage due to accidental faults and ensuring NE5532DR circuit operation reliability.

Technical Specifications

Typical Applications

• In the field of audio equipment (such as Hi-Fi speakers, headphone amplifiers, microphone pre-amplifiers), NE5532DR can accurately amplify weak signals from microphones or audio sources with its ultra-low input noise of 5nV/√Hz. Meanwhile, its high slew rate of 9V/μs can restore high-frequency audio details and avoid sound distortion. Its wide power supply range adapts to the power supply design of different audio equipment, making it a classic choice for NE5532DR audio amplification.
• In industrial sensor signal processing scenarios (such as pressure sensors, temperature sensors, liquid level sensors), the 100dB high CMRR of NE5532DR can effectively filter electromagnetic interference and power noise in industrial environments, ensuring pure amplification of mV-level sensor signals. The 0°C~70°C operating temperature range adapts to conventional workshop environments, and the 24V~32V output swing can cover the signal dynamic range of most sensors, improving NE5532DR industrial sensing accuracy.
• In medical instruments (such as ECG monitors, oximeters, portable diagnostic devices), the low-noise characteristic of NE5532DR can reduce interference to weak medical signals (such as ECG signals, blood oxygen signals) and ensure data acquisition accuracy. The built-in protection mechanism prevents device damage due to circuit abnormalities, meeting the strict reliability requirements of medical equipment and adapting to NE5532DR medical signal processing needs.
• In the signal conditioning link of communication systems (such as RF module signal amplification, data transmission link signal shaping), the 1MHz unity-gain bandwidth and high slew rate of NE5532DR enable efficient amplification and synchronization of communication signals. Its wide power supply range adapts to the power supply schemes of base stations, routers and other equipment, and the output short-circuit protection reduces the failure risk of outdoor communication equipment, meeting NE5532DR communication signal conditioning needs.
• In consumer electronics devices (such as smart bracelet sensor modules, small testing instruments), the SOIC-8 package of NE5532DR saves PCB space, adapting to the compact design of consumer electronics. The ±3V low power supply lower limit is compatible with lithium battery dual power supplies (such as two 3.7V lithium batteries in series for ±3.7V), the low quiescent current (8mA~16mA) extends device battery life, and the dual op-amp integrated design can process two signals simultaneously (such as temperature + heart rate), improving NE5532DR consumer electronics integration efficiency.

Why Choose NE5532DR ?

• Industry-Leading Noise Performance: Ultra-low input noise of 5nV/√Hz (1kHz), which is 30% lower than that of ordinary op-amps, can maximize the retention of weak signal details. It is the core advantage of NE5532DR weak signal amplification, especially suitable for scenarios requiring high signal purity such as audio and medical applications;
• High-Speed Signal Processing Capability: 9V/μs slew rate + 1MHz unity-gain bandwidth can process high-speed analog signals with frequency ≤1MHz, avoiding signal "tail" distortion, adapting to NE5532DR high-frequency signal conditioning scenarios without the need for additional high-speed op-amp upgrades;
• Strong Multi-Scenario Adaptability: ±3V~±20V wide power supply range covers the mainstream power supply schemes of consumer electronics (lithium batteries), industrial equipment (±15V) and medical instruments (±12V). The 0°C~70°C operating temperature adapts to most indoor environments, reducing NE5532DR cross-field application costs;
• High Reliability Guarantee: Original production by Texas Instruments, RoHS compliant (lead-free), built-in input protection and output short-circuit protection. The device failure rate is as low as 0.001%/1000 hours (commercial standard), improving NE5532DR circuit long-term stability;
• Significant Cost-Effectiveness: Integrates 2 independent low-noise op-amps in a single package. The SOIC-8 package supports automated SMT placement, and the bulk purchase cost is 15%~20% lower than that of similar low-noise op-amps, balancing NE5532DR performance and cost control.
