TL071CN

TL071CN Description

The TL071CN from STMicroelectronics is a high-performance JFET-input operational amplifier designed for precision analog applications. Housed in an 8-pin DIP package, this single-channel op-amp delivers low noise, high input impedance, and wide bandwidth, making it ideal for signal conditioning, audio processing, and instrumentation. With a supply voltage range of 6V to 36V, it supports flexible power configurations while maintaining low input bias current (20 pA) and low offset voltage (3 mV) for accurate signal amplification. Its 4 MHz gain bandwidth product (GBW) and 16V/µs slew rate ensure fast response times, suitable for dynamic signal processing.
