What Is the TL074? Quad JFET Op-Amp: Pinout and Uses
The TL074 is an IC with four JFET-input op-amps in one package. It is the quad version of the TL072; it offers high input impedance and ~3 MHz speed. It is used in multi-channel audio processing (mixers, equalizers, filter banks) and high-impedance sensor buffers; its input does not reach ground.
The TL074 is an IC with four JFET-input operational amplifiers (op-amps) in a single 14-pin package. It is the quad version of the TL072: high input impedance, low noise, ~3 MHz speed. For the concept, see what is an op-amp.
What is the TL074 used for?
Multi-channel audio processing (mixers, equalizers, active filter banks), multi-channel sensor buffers and analog designs that need four amplifier stages. Its JFET input is ideal for high-impedance sources.
TL074 pinout (DIP-14 / SOIC-14)
| Pin | Function | Pin | Function |
|---|---|---|---|
| 1 | Output 1 | 14 | Output 4 |
| 2 | Input 1− | 13 | Input 4− |
| 3 | Input 1+ | 12 | Input 4+ |
| 4 | V+ (VCC) | 11 | V− (VEE) |
| 5 | Input 2+ | 10 | Input 3+ |
| 6 | Input 2− | 9 | Input 3− |
| 7 | Output 2 | 8 | Output 3 |
The layout is the standard quad op-amp (same as the LM324; supply pin 4 = V+, pin 11 = V−).
Key electrical specifications
| Parameter | Typical value |
|---|---|
| Number of op-amps | 4 (JFET input) |
| Supply (dual) | ±5 V – ±18 V |
| GBW | ~3 MHz |
| Slew rate | ~13 V/µs |
Limitations
- Its input does not reach ground → not directly suited to single-supply ground-sensing; the LM324 is preferred there.
- The output is not rail-to-rail.
TL074 equivalents and alternatives
- TL072: the dual version.
- TL071: the single version.
- LM324: single-supply, ground-sensing quad op-amp.
- MCP6004: quad rail-to-rail, low voltage.
