LM7171BIN

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.
