Dual J-FET op-amp in an 8-pin DIP
The TL072IPE4 is a dual J-FET input operational amplifier from Texas Instruments, housed in an 8-pin PDIP package for through-hole assembly.
Parametric fit for signal-chain designs
Each of the two amplifiers draws 1.4 mA supply current, keeping the total quiescent draw under 3 mA for the dual package — a practical choice for multi-channel boards where thermal budget matters. The J-FET input stage holds input bias current at 65 pA typical, which preserves signal integrity in high-impedance sensor interfaces and photodiode amplifiers where bias current error would otherwise dominate the offset.
