Quad J-FET op-amp in 14-SOIC
The STMicroelectronics TL074BCDT is a quad J-FET input operational amplifier in a 14-SOIC surface-mount package. The four amplifiers share a common supply range up to 36 V and draw 1.4 mA per channel.
Parametric fit for signal conditioning
The J-FET input stage keeps bias currents in the picoamp range, which preserves accuracy in high-impedance sensor interfaces and integrator circuits. Each of the four channels can source or sink 40 mA, enough to drive ADC inputs, small-signal relays, or headphone loads directly. The 36 V maximum supply span gives headroom for ±15 V industrial rails or single-supply designs up to 30 V.
