LM611IM/NOPB Description

The LM611IM/NOPB from Texas Instruments is a general-purpose operational amplifier designed for precision analog applications. Housed in a 14-SOIC package, this single-channel op-amp delivers a gain bandwidth product of 800 kHz and a slew rate of 0.7V/µs, making it suitable for moderate-speed signal conditioning. With a wide supply voltage range (4V to 36V) and low input bias current (25 nA), it excels in environments requiring stable performance across varying power conditions. Though now obsolete, it remains a reliable choice for legacy designs due to its low power consumption (210µA supply current) and ROHS3 compliance.

LM611IM/NOPB Features

• Low Power Operation: 210µA supply current minimizes energy usage in battery-powered systems.
• Wide Supply Range: Supports 4V to 36V, ideal for industrial and automotive applications.
• High Output Drive: 25mA output current enables direct driving of small loads.
• Low Input Offset Voltage: 1.5mV ensures accuracy in precision circuits.
• Surface-Mount Packaging: 14-SOIC for compact PCB layouts.
• REACH Unaffected: Compliant with environmental regulations.

LM611IM/NOPB Applications

The LM611IM/NOPB is well-suited for:

• Sensor Signal Conditioning: Amplifying low-level signals from thermocouples or strain gauges.
• Active Filters: Implementing bandpass or low-pass filters in audio systems.
• Power Supply Control: Error amplification in voltage regulators.
• Portable Instruments: Low-power operation benefits handheld measurement devices.
• Industrial Automation: Robust performance in harsh environments with wide voltage fluctuations.

Conclusion of LM611IM/NOPB

While obsolete, the LM611IM/NOPB remains a versatile op-amp for precision, low-power, and moderate-speed applications. Its wide supply range, low noise, and stable performance make it a legacy favorite for engineers maintaining or upgrading older systems. For new designs, consider TI’s modern alternatives with enhanced features, but the LM611IM/NOPB’s proven reliability ensures continued relevance in niche applications.
