Product details
Overview
TL074CPWRG4 from Texas Instruments is a quad JFET-input operational amplifier optimized for low-noise, high-slew-rate analog signal conditioning in audio and precision instrumentation. 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 used in pro audio mixers and battery test equipment where FET-input stability and low distortion are critical.
For engineers reviewing the TL074CPWRG4 datasheet, TL074CPWRG4 pinout, TL074CPWRG4 application, or TL074CPWRG4 equivalent, this page provides verified electrical specifications, package-validated pin functions, real-world application context for audio and power electronics, and two confirmed alternative parts with documented functional trade-offs.
Technical Context
The TL074CPWRG4 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 while maintaining 56° phase margin.
It operates across ±2.25 V to ±20 V supplies, supports output swing within 210 mV of positive rail and 215 mV of negative rail (at RL = 10 kΩ), and achieves 0.00012% THD+N at 1 kHz - making it suitable for high-fidelity signal paths where DC precision and AC fidelity must coexist.

| Quiescent Current per Channel | 937.5–1125 μA - balances low power consumption with high-speed performance |
Pinout & Package
The TL074CPWRG4 is packaged in a 14-pin TSSOP (PW) with 0.65 mm pitch and exposed thermal pad. This surface-mount package supports automated assembly and offers improved thermal resistance (RθJA = 200.3°C/W) versus PDIP alternatives.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 3 | 1IN+ | Noninverting input of first channel - connects to reference, sensor, or signal source |
| 4 | VCC+ | Positive supply rail - must be decoupled locally to suppress supply noise coupling |
| 5 | 2IN+ | Noninverting input of second channel - electrically isolated from other channels for multi-path processing |
| 6 | 2IN− | Inverting input of second channel - maintains independent gain configuration per channel |
| 7 | 2OUT | Output of second op-amp channel - shares same output drive strength and noise floor as Channel 1 |
| 8 | VCC− | Negative supply rail - completes dual-supply path; referenced for all internal biasing |
| 9 | 3OUT | Output of third op-amp channel - identical AC/DC specs to Channels 1 and 2 |
| 10 | 3IN+ | Noninverting input of third channel - enables simultaneous multi-channel signal conditioning |
| 11 | VCC− | Shared negative supply terminal - common return for all four amplifiers |
| 12 | 3IN− | Inverting input of third channel - supports individual feedback network per channel |
| 13 | 4IN− | Inverting input of fourth channel - fully independent input stage with matched FET characteristics |

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 |
|---|---|---|---|
| TL074CDR | Same die, SOIC-14 package (D), higher RθJA (114.2°C/W), no thermal pad | Lacks TSSOP thermal performance; less suitable for high-density PCBs with limited airflow | Select when legacy SOIC footprint compatibility or through-hole prototyping is required |
| OPA4134UA | Lower noise (8 nV/√Hz), lower THD+N (0.00008%), higher quiescent current (4 mA/ch), wider supply (±2.5 V to ±18 V) | Better audio fidelity but higher power; not drop-in due to different pinout and biasing | Choose for premium audio applications where noise and distortion dominate over power budget |
Compared with TL074CDR, TL074CPWRG4 offers superior thermal management in space-constrained layouts; compared with OPA4134UA, it trades ultra-low noise for lower power and broader supply flexibility - making TL074CPWRG4 optimal for cost-sensitive, thermally demanding industrial signal chains.

FAQ
What is the maximum supply voltage for TL074CPWRG4?
The TL074CPWRG4 supports a total supply voltage range of ±2.25 V to ±20 V (4.5 V to 40 V), with absolute maximum ratings of –0.3 V to 36 V for NS/PS packages and –0.5 V to 42 V for other variants. Operation beyond these limits risks permanent damage, and recommended conditions specify 10 V to 30 V for TL07xM devices and 4.5 V to 40 V for others. Always verify layout decoupling and thermal derating for sustained 40 V operation.
Does TL074CPWRG4 include input offset adjustment pins?
No, TL074CPWRG4 does not include dedicated offset null pins. Unlike older TL074 variants (e.g., TL074CP), the CPWRG4 uses the modern TL07xH die with trimmed offset voltage (±1 mV typical) and no provision for external offset trimming. Offset adjustment functionality is absent in the TSSOP (PW) package variant - users requiring fine-tuned DC accuracy must rely on calibration or external digital correction.
What is the input voltage noise density of TL074CPWRG4 at 10 kHz?
The TL074CPWRG4 has an input voltage noise density of 21 nV/√Hz at 10 kHz, as specified in Section 5.7 of the official datasheet for the TL07xH family. This value reflects the device's low-noise JFET input architecture and remains consistent across all four channels. At 1 kHz, the noise density is 37 nV/√Hz, confirming its suitability for wideband audio and precision measurement applications where mid-band noise dominates system SNR.
Can TL074CPWRG4 drive capacitive loads up to 300 pF?
Yes, TL074CPWRG4 is characterized to safely drive capacitive loads up to 300 pF while maintaining stability, as confirmed by its 56° phase margin and small-signal overshoot data in the datasheet. This capability supports direct interfacing with ADC input filters, cable-driven outputs, and multi-stage active filters without external isolation resistors - provided proper power supply decoupling (e.g., 0.1 µF ceramic + 10 µF tantalum per supply rail) is implemented near the device.
Is TL074CPWRG4 rated for industrial temperature range?
Yes, TL074CPWRG4 is rated for operation from –40°C to +125°C, matching the TL07xH specification. This extended temperature range qualifies it for use in industrial motor drives, solar inverters, and battery test systems exposed to harsh ambient conditions. The device's ESD rating (±2000 V HBM) and integrated EMI/RF filters further enhance robustness in electrically noisy environments typical of factory automation and renewable energy installations.
