TL072Dual FET-input operational amplifier
Two high-impedance analog channels in one compact IC.
TL072 integrates two FET-input operational amplifiers. Each channel compares a pair of input voltages and uses external negative feedback to control its gain. The physical example uses channel A as a gain-of-three amplifier and channel B as a voltage follower. A shared 0.50 V input gives ideal outputs of 1.50 V and 0.50 V from a ±15 V supply. This page follows TI’s July 2025 reference for the C-grade P and D packages. Its revised P/D specifications differ from the legacy PS package; the manufacturer’s package-specific columns are kept separate.

Compare each input pair
The FET input stage draws very little bias current at room temperature. Source resistance, board leakage and temperature still affect the input error.
Set two different gains
Channel A uses 20 kΩ feedback and 10 kΩ to the 0 V midpoint, giving a gain of three. Channel B directly feeds its output back to its negative input, giving unity gain.
Check headroom and speed
With a 0.50 V input, the ideal outputs are 1.50 V and 0.50 V. Real output also depends on input offset, resistor accuracy, loading, noise and signal frequency.
Both channels share the supply rails but have independent feedback paths. The diagram shows a low-frequency, light-load example; use the specified limits for your actual circuit.
