Key parametrics for BOM fit
The TL084BCN is a quad J-FET input op-amp with a 13V/µs slew rate and 3 MHz gain-bandwidth product — fast enough for audio-band filtering and moderate-speed analog signal conditioning without the stability headaches of a decompensated amplifier. Total supply current is 1.4mA across all four channels, with input bias current of 30 pA — this keeps the power budget low in multi-channel data acquisition boards while preserving signal integrity from high-impedance sensors. Supply span from 10V to 30V allows operation on standard ±5V to ±15V rails, making it a drop-in for existing TL084-based designs without rail rework.
Housed in a 14-DIP (0.300", 7.62mm) through-hole package, the 14-PDIP supplier package footprint mates with standard 0.100-inch pitch sockets or direct solder — no SMT reflow needed, but the board must accommodate the larger hole pattern and component height.
