The TL072CN from STMicroelectronics is a low-noise, high-speed J-FET input dual operational amplifier, built as a monolithic integrated circuit incorporating well-matched, high-voltage J-FET and bipolar transistors. In the order code TL072CN, the letter “C” designates the commercial temperature grade (0 °C to +70 °C) and the letter “N” designates the 8-pin plastic DIP package (DIP-8).
The J-FET input stage gives the TL072CN a very high input impedance of 10¹² Ω, together with low input bias and offset currents (20 pA and 5 pA typ at 25 °C) and a low offset voltage temperature coefficient (10 µV/°C). It combines a high slew rate of 16 V/µs (typ) with a typical gain bandwidth product of 4 MHz, while keeping noise down to 15 nV/√Hz and total harmonic distortion to just 0.01% (typ), with 120 dB channel separation between the two amplifiers.
