Each amplifier incorporates well-matched, high-voltage JFET and bipolar transistors in a monolithic integrated circuit. The JFET input stage provides very high input impedance and extremely low input bias current (65pA typical), making it ideal for high-impedance source applications. The 3MHz gain bandwidth product and 13V\/\u00b5s slew rate support audio and moderate-frequency signal processing. Total harmonic distortion of 0.003% and input noise of 18nV\/\u221aHz make the TL072 the industry standard for professional audio and hi-fi applications. The CD suffix indicates 0\u00b0C to +70\u00b0C commercial temperature range.","working_principle":"The TL072CDR uses a JFET-input stage followed by a bipolar output stage. The N-channel JFET differential input pair provides very high input impedance and low input bias current because JFET gates are reverse-biased PN junctions that draw negligible DC current. The JFET input stage also offers low noise (18nV\/\u221aHz) and excellent CMRR (100dB typical). The input common-mode range extends to the positive supply rail (VCC+), accommodating single-supply configurations. The bipolar output stage provides output short-circuit protection and can swing within approximately 1.5V of each supply rail. Internal frequency compensation ensures stability in unity-gain configurations without external components.","pin_description":"
