Product details
Overview
TL074CPW from Texas Instruments is a quad JFET-input operational amplifier optimized for low-noise, high-slew-rate signal conditioning in audio and precision analog systems. It delivers 20 V/μs slew rate, 37 nV/√Hz input voltage noise at 1 kHz, ±2.25 V to ±20 V dual-supply operation, and rail-to-rail common-mode input range extending to VCC+. It is widely deployed in pro audio mixers and battery test equipment where FET-input stability and low distortion are critical.
For engineers reviewing the TL074CPW datasheet, TL074CPW pinout, TL074CPW application, or TL074CPW equivalent, key selection criteria include its quad-channel TSSOP-14 package, guaranteed 1 mV max offset voltage (TL074H variant), 5.25 MHz gain-bandwidth product, output short-circuit protection, and compatibility with ±15 V industrial supply rails.
Technical Context
The TL074CPW implements a high-impedance JFET differential input stage followed by a Class AB output stage, enabling low input bias current (±1 pA typ) and wide common-mode range including VCC+. Its internal compensation ensures unity-gain stability with capacitive loads up to 300 pF.
It operates across –40°C to +85°C (TL074C grade) and supports dual supplies from ±2.25 V to ±20 V or single supply from 4.5 V to 40 V. The device features integrated EMI filtering and 2 kV HBM ESD protection, making it suitable for electrically noisy environments like motor drive feedback loops.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables compact multi-stage filtering or simultaneous signal conditioning of four analog channels without board area penalty. |
| Slew Rate | 20 V/μs - supports faithful reproduction of fast transients in audio and control-loop applications up to ~300 kHz full-power bandwidth. |
| Input Voltage Noise | 37 nV/√Hz @ 1 kHz - ensures minimal added noise in microphone preamps and sensor front-ends requiring high dynamic range. |
| Supply Voltage Range | ±2.25 V to ±20 V - compatible with standard ±15 V industrial rails and low-voltage portable systems down to ±2.25 V. |
| Input Offset Voltage | 3 mV max (TL074C) - provides baseline DC accuracy sufficient for non-critical amplification and active filter stages without trimming. |
| Gain-Bandwidth Product | 5.25 MHz - allows stable closed-loop gains up to ~100 at 50 kHz, supporting anti-aliasing and tone-control filters. |
| Common-Mode Input Range | Includes VCC+ - permits direct sensing of signals referenced to positive rail, e.g., high-side current monitoring in battery systems. |
Pinout & Package
TSSOP-14 (PW) package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, thermally enhanced exposed pad (not electrically connected), rated for surface-mount reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier A output - drives external load or next stage; capable of ±26 mA short-circuit current. |
| 2 | 1IN– | Inverting input of Amp A - high-impedance JFET node; sensitive to PCB leakage and layout parasitics. |
| 3 | 1IN+ | Noninverting input of Amp A - same high-Z characteristics; used for unity-gain buffers and instrumentation front-ends. |
| 4 | VCC+ | Positive power supply - must be decoupled locally with 0.1 μF ceramic capacitor to minimize supply-induced noise. |
| 5 | 2IN+ | Noninverting input of Amp B - independent channel; no crosstalk with Amp A under normal operating conditions. |
| 6 | 2IN– | Inverting input of Amp B - identical electrical behavior to Pin 2; supports differential pair configurations. |
| 7 | 2OUT | Amplifier B output - electrically isolated from Amp A output; shares VCC+/VCC– rails. |
| 8 | VCC– | Negative power supply - reference for all four amplifiers; requires low-impedance return path to ground plane. |
| 9 | 3OUT | Amplifier C output - completes first half of quad; usable for multi-pole filter sections or parallel gain stages. |
| 10 | 3IN+ | Noninverting input of Amp C - matches Pin 3 and Pin 5 performance; maintains channel independence. |
| 11 | VCC– | Shared negative rail - not a dedicated pin; Pin 8 serves as sole VCC– connection for all four op-amps. |
| 12 | 4IN+ | Noninverting input of Amp D - enables full quad utilization in 4-channel data acquisition or stereo+effects processing. |
| 13 | 4IN– | Inverting input of Amp D - functionally identical to Pins 2 and 6; supports balanced input topologies. |
| 14 | 4OUT | Amplifier D output - final channel output; fully specified for drive capability and settling time per datasheet. |
Key Features
| Feature | Design Value |
|---|---|
| Low input bias current | ±1 pA typical - minimizes voltage error in high-impedance sensor interfaces (e.g., piezoelectric pickups, pH electrodes). |
| Output short-circuit protection | ±26 mA continuous limit - prevents latch-up or thermal runaway during accidental output shorts in test equipment. |
| Wide supply range | 4.5 V to 40 V single or ±2.25 V to ±20 V dual - eliminates need for level-shifting in mixed-voltage systems like solar inverters. |
| Low total harmonic distortion | 0.003% typical at 1 kHz - preserves signal fidelity in pro audio line drivers and analog synthesizer signal paths. |
| EMI rejection ratio | 53 dB @ 1 GHz - suppresses RF interference from switching power supplies and wireless modules in embedded designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad JFET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL074IPW | Same pinout and electrical specs, but rated for –40°C to +85°C industrial temperature range (identical to TL074C). | No functional difference; TL074IPW is legacy marking for same TL074C-grade device in TSSOP-14. | Select TL074IPW only if legacy BOM alignment is required; TL074CPW is current orderable part number. |
| RC4136N | Higher 4.5 mV max offset, lower 10 V/μs slew rate, no EMI filtering, and 1.8 mA/ch quiescent current vs 0.94 mA/ch. | Less suitable for low-noise audio; acceptable for general-purpose industrial signal conditioning where cost is primary driver. | Choose RC4136N only when budget constraints outweigh noise/speed requirements and EMI immunity is not critical. |
Compared with TL074IPW, TL074CPW offers identical performance but reflects updated TI part numbering; versus RC4136N, TL074CPW delivers 50% higher slew rate, half the input noise, and integrated EMI rejection-critical for audio fidelity and noisy motor-drive environments.

FAQ
What is the maximum supply voltage for TL074CPW?
The TL074CPW supports a total supply voltage range of 4.5 V to 40 V for single-supply operation, or ±2.25 V to ±20 V for dual-supply use. Absolute maximum ratings specify 42 V across VCC+ and VCC– for non-NS/PS packages, but recommended operation stays within 40 V to ensure long-term reliability and specified performance per the datasheet.
Does TL074CPW have rail-to-rail input capability?
Yes, TL074CPW features a rail-inclusive common-mode input voltage range extending to VCC+, meaning the input can accept signals at or slightly above the positive supply rail. However, it does not support rail-to-rail output swing-the output typically saturates within 105–215 mV of each rail under 10 kΩ load.
Can TL074CPW drive capacitive loads?
Yes, TL074CPW is characterized to safely drive capacitive loads up to 300 pF while maintaining stability and specified settling time. For loads exceeding 300 pF, external isolation resistance (e.g., 10–100 Ω in series with the output) is recommended to prevent peaking or oscillation, especially in unity-gain configurations.
What is the input offset voltage specification for TL074CPW?
The TL074CPW (C-grade) has a maximum input offset voltage of 10 mV at 25°C, with a typical value of 3 mV. Over the full operating temperature range (0°C to 70°C), the maximum drift is ±18 µV/°C, resulting in predictable DC error accumulation in precision DC-coupled stages.
Is TL074CPW pin-compatible with other TL074 variants in TSSOP-14?
Yes, TL074CPW is fully pin-compatible with TL074IPW, TL074ACPW, and TL074BCPW in the PW (TSSOP-14) package. All share identical pinout, footprint, and thermal pad configuration; differences lie only in electrical grading (offset, drift, noise) and temperature range-not mechanical or connectivity design.
