JFET quad op-amp with automotive qualification

The STMicroelectronics TL084BCPT is a JFET-input quad operational amplifier rated for automotive applications under AEC-Q100. Four independent channels in a single 14-TSSOP package, each drawing 1.4 mA supply current. The JFET input stage delivers 20 pA input bias current, making this part a strong fit for high-impedance sensor conditioning, active filters, and audio signal chains where input offset drift matters.

Dynamic performance — 4 MHz GBW, 16 V/µs slew

Gain-bandwidth product is 4 MHz with a slew rate of 16 V/µs. These numbers set the usable bandwidth for a given closed-loop gain: at a gain of 10 the small-signal bandwidth is roughly 400 kHz, and the full-power bandwidth before slew limiting is about 250 kHz at 10 V output swing. The 40 mA per-channel output current can drive modest loads like a 600 Ω audio line or a 10-bit ADC input without an external buffer.

Operates from a single supply of 6 V to 36 V, or split supplies.

Frequently asked questions

What is the replacement or equivalent for TL084BCPT?

The closest pin-compatible replacement is the standard TL084 series in 14-TSSOP, such as the TL084CDT (commercial temp) or TL084IDT (industrial temp). Both share the same JFET quad architecture, 14-TSSOP footprint, and similar 4 MHz GBW / 16 V/µs slew. The difference is the automotive AEC-Q100 qualification on the BC suffix — the standard variants do not carry that grade. Check the supply chain for the exact temperature grade you need.
