The OP275 is the first amplifier to feature the Butler Amplifier front-end. This new front-end design combines both bipolar and JFET transistors to attain amplifiers with the accuracy and low noise performance of bipolar transistors, and the speed and sound quality of JFETs. Total Harmonic Distortion plus Noise equals that of previous audio amplifiers, but at much lower supply currents. https://elecena.pl/product/9697671/op275gsz-operational-amplifier-9mhz 2017-08-05 https://elecena.pl/product/9697671/op275gsz-operational-amplifier-9mhz 2018-03-30 https://elecena.pl/product/9697671/op275gsz-operational-amplifier-9mhz 2018-04-25 https://elecena.pl/product/9697671/op275gsz-operational-amplifier-9mhz 2018-12-16 https://elecena.pl/product/9697671/op275gsz-operational-amplifier-9mhz 2019-04-02 https://elecena.pl/product/9697671/op275gsz-operational-amplifier-9mhz 2021-05-22 https://elecena.pl/product/9697671/op275gsz-operational-amplifier-9mhz 2022-07-03 https://elecena.pl/product/9697671/op275gsz-operational-amplifier-9mhz 2022-11-07 https://elecena.pl/product/9697671/op275gsz-operational-amplifier-9mhz 2025-02-02 https://elecena.pl/product/9697671/op275gsz-operational-amplifier-9mhz 2025-12-12 https://elecena.pl/product/9697671/op275gsz-operational-amplifier-9mhz 2026-02-03 https://elecena.pl/product/9697671/op275gsz-operational-amplifier-9mhz 2026-09-20
