LM7171BIN Description

The LM7171BIN from Texas Instruments is a high-speed voltage feedback operational amplifier designed for precision applications requiring wide bandwidth and fast slew rates. Part of the VIP™ III series, this obsolete but robust IC delivers exceptional performance with a 200 MHz gain bandwidth product, 220 MHz -3dB bandwidth, and an ultra-fast 4100V/µs slew rate, making it ideal for high-frequency signal processing. Operating over a 5.5V to 36V supply range, it features low input bias current (2.7 µA) and low offset voltage (200 µV), ensuring accuracy in sensitive circuits. Packaged in an 8-pin DIP (Through Hole), the LM7171BIN is suited for prototyping and industrial applications where reliability is critical.

LM7171BIN Features

• High-Speed Performance: 200 MHz GBW, 220 MHz bandwidth, and 4100V/µs slew rate enable rapid signal amplification.
• Wide Supply Range: Operates from ±2.75V to ±18V (5.5V–36V span), accommodating diverse power requirements.
• Low Input Errors: 200 µV offset voltage and 2.7 µA bias current enhance precision in DC-coupled systems.
• High Output Drive: Delivers 118 mA output current, suitable for driving low-impedance loads.
• Robust Construction: MSL 1 (Unlimited) moisture sensitivity and REACH Unaffected compliance ensure durability.
• Through-Hole Package: 8-DIP for easy integration into legacy or prototyping boards.

LM7171BIN Applications

• High-Speed Data Acquisition: ADC/DAC buffers, oscilloscopes, and RF systems benefit from its bandwidth and slew rate.
• Video and Imaging Systems: Ideal for HD video amplifiers, CCD signal conditioning, and pixel clock drivers.
• Test and Measurement Equipment: Precision signal generators and active filters leverage its low distortion.
• Industrial Control: Motor drive circuits, PWM amplifiers, and servo controllers utilize its high output current.
• Obsolete but Reliable: Still favored in maintenance-critical systems due to its proven performance.

Conclusion of LM7171BIN

The LM7171BIN remains a standout choice for engineers needing high-speed, high-precision amplification despite its obsolete status. Its combination of wide bandwidth, fast slew rate, and robust output drive makes it indispensable in video, RF, and industrial applications. While newer alternatives exist, the LM7171BIN’s reliability and through-hole packaging ensure continued relevance in legacy designs and prototyping environments. Texas Instruments’ VIP™ III architecture underscores its legacy as a high-performance op-amp for demanding analog systems.
