TL072IDR – TEXAS INSTRUMENTS

The Texas Instruments TL072IDR 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 ±15V supply voltage range, exhibiting a typical input bias current of 25nA and a maximum input offset voltage of 6mV, significantly lower than many comparably priced alternatives. Its high input impedance (10¹² Ω) makes it ideal for applications requiring minimal loading effects on preceding stages._x000D_

The TL072IDR’s low noise characteristics (typically 18nV/√Hz at 1kHz) are beneficial in precision instrumentation and audio circuitry. The dual configuration allows for compact implementations of instrumentation amplifiers, active filters, and other applications requiring two independent op-amps. Its wide bandwidth (typically 3MHz) makes it suitable for many signal processing tasks. However, its relatively low slew rate (2V/µs) may limit its application in high-speed switching circuits._x000D_

The JFET input stage contributes to its low input bias current and high input impedance, making it a superior choice over bipolar input op-amps in high-impedance applications where drift is critical. Designers should consider its relatively low output current capability (typically 20mA) when selecting this component for high-current applications. The TL072IDR offers a robust and reliable solution for a wide variety of low-power, precision analog signal processing tasks.
