JFET quad op-amp for automotive signal chains
The STMicroelectronics TL084BIPT is a quad JFET-input operational amplifier qualified to AEC-Q100, making it suitable for automotive sensor conditioning, battery monitoring, and motor-drive feedback paths where high input impedance and low bias current matter. Each of the four channels draws 1.4 mA supply current, and the part operates across a 6 V to 36 V supply span — wide enough to handle 12 V and 24 V automotive rails without an extra regulator.
Speed and precision for filtering and buffering
With a 4 MHz gain-bandwidth product and 16 V/µs slew rate, the TL084BIPT can handle audio-band active filters, anti-aliasing stages, and fast comparator circuits without excessive phase lag.
