TL071IDR – TEXAS INSTRUMENTS

The Texas Instruments TL071IDR is a dual low-power, JFET-input operational amplifier (op-amp) packaged in a 8-lead PDIP (plastic dual in-line package). It operates from a ±3V to ±18V supply voltage range, offering flexibility in various power supply designs. The device boasts a typical input bias current of only 25nA, significantly reducing input offset voltage drift and improving accuracy in low-signal applications. Its high input impedance (typically 10¹² Ω) minimizes loading effects on preceding stages. The TL071IDR features a unity-gain bandwidth of approximately 3MHz and a slew rate of 13V/µs, suitable for moderate-speed signal processing. Common applications include instrumentation amplifiers, precision integrators, and general-purpose analog signal conditioning where low input bias current and high input impedance are critical. Compared to bipolar op-amps, the JFET input stage of the TL071IDR provides superior input offset voltage characteristics, making it ideal for applications requiring high accuracy and stability over temperature variations. The PDIP package offers ease of handling and compatibility with through-hole PCB mounting techniques. However, its relatively low slew rate limits its applicability in high-speed applications.
