The TL071 is the single-channel member of the low-noise JFET-input family that ran the analog benches of the 1980s and still repairs them - audio front ends, instrumentation, filters, sample-and-holds and half of every synth ever: TL071 single, TL072 dual, TL074 quad, with the TL08x twins (TL081/082/084) as the higher-noise, otherwise interchangeable siblings. The channel-count letter is the socket definition, the A/B suffix is offset grade, and the family quirks - offset-null pins on the single only, and phase inversion near the negative rail - are what substitutions in this family actually get wrong.
Same Socket, Higher Noise
Shenzhen Spot Stock (24-48h Dispatch)
The same JFET-input architecture and pinout with noise around 25 nV/root-Hz against about 18 for the TL071 - the low-noise selection came from the 07x die.
Same supply envelopes and slew (about 13V/us), same 3MHz-class gain-bandwidth.
The Battery-Diet Sibling
Shenzhen Spot Stock (24-48h Dispatch)
The low-power member of the family: same JFET inputs and pinout, supply current cut to the microamp-conscious class at the cost of bandwidth (about 1MHz class against 3MHz).
Same envelopes; designed for portable instruments.
The Dual - Same Die, Different Count
Shenzhen Spot Stock (24-48h Dispatch)
Two channels of the same amplifier in the classic dual pinout (1 OUT1, 2 IN1-, 3 IN1+, 4 V-, 5 IN2+, 6 IN2-, 7 OUT2, 8 V+): no offset-null pins in this body.
Same supply and slew per channel.
The Modern Re-issue - a Different Animal
Shenzhen Spot Stock (24-48h Dispatch)
TIs 2020-era successor: same pinout and socket, but a CMOS input stage instead of JFET - about 20V/us slew, 1mV-class offset, and different noise character (about 37 nV/root-Hz).
Wider modern supply window (about +/-2.25V to +/-20V).
Q: What is the difference between TL071 and TL081?
A: Same architecture, pinout and grade system - the 07x family is the low-noise selection of the 08x family (about 18 vs 25 nV/root-Hz). Interchangeable everywhere; in low-level audio or instrumentation the 081 replacement raises the noise floor.
Q: Can a TL072 replace a TL071?
A: No - the 072 is the dual-channel member with a completely different 8-pin layout and no offset-null pins. Same die per channel, different socket definition.
Q: Why does my TL071 circuit misbehave near ground on a single supply?
A: The family phase-inverts when the input is driven below its common-mode limit (roughly 3V above the negative rail). Symptom: the output flips high instead of staying off. Keep inputs inside the common-mode window or raise the negative rail.
Runs from a 7 V to 36 V single or dual supply.
Supplied in Tube, 8-DIP (0.300", 7.62 mm) body, through-hole mount. The 8-PDIP footprint is socket-compatible and protoboard-friendly — useful for repair swaps, breadboard prototypes, or low-volume builds where SMT reflow isn't available.
