JFET input, four channels, low supply draw
The TL034CNS: It delivers a 1.1 MHz gain-bandwidth product and a 5.1V/µs slew rate — enough for audio processing, active filters, and slow data acquisition front-ends. Each of the four amplifiers draws 870 µA, keeping the total quiescent current under 3.5 mA for the whole package. The JFET input stage holds input bias current at 2 pA, which is the main reason to pick this part over a bipolar op-amp: it won't load high-impedance sources like photodiodes, pH probes, or piezoelectric sensors.
The TL034CNS runs from a single supply between 10 V and 30 V. Input offset voltage is 790 µV typical.
