Product details
Overview
TL074CPWR 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, 1 mV typical input offset voltage, 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 impedance and low distortion are critical.
For engineers reviewing the TL074CPWR datasheet, TL074CPWR pinout, TL074CPWR application, or TL074CPWR equivalent, key selection criteria include its quad-channel FET-input architecture, guaranteed 125 dB open-loop gain, 5.25 MHz gain-bandwidth product, output short-circuit protection, and compatibility with ±15 V industrial supply rails - all validated for operation from –40°C to +85°C.
Technical Context
The TL074CPWR implements a high-impedance JFET differential input stage followed by a Class AB output stage, enabling ultra-low input bias current (±1 pA typ) and wide common-mode range including VCC+. Its internal compensation ensures stable unity-gain operation with up to 300 pF capacitive load drive.
It features integrated EMI/RF filters and 2 kV HBM ESD protection, supporting robust performance in electrically noisy environments such as motor drive feedback loops and solar inverter sensor interfaces without external filtering.

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 |
|---|---|---|---|
| TL074IPWR | Same pinout and electrical specs, but rated for –40°C to +85°C industrial temp range (vs. TL074CPWR's 0°C to 70°C) | Preferred for extended-temperature industrial deployments where ambient exceeds 70°C | Select TL074IPWR when operating above 70°C ambient; otherwise TL074CPWR is cost-optimized for commercial-grade designs |
| RC4136N | Higher 15 V/μs slew rate, 10 nV/√Hz noise at 1 kHz, but only available in PDIP-14; no TSSOP option | Used where lower noise dominates over package size, e.g., lab-grade instrumentation | Choose RC4136N only if sub-20 nV/√Hz noise is mandatory and through-hole assembly is acceptable |
Compared with TL074IPWR and RC4136N, the TL074CPWR offers optimal balance of low-cost TSSOP packaging, proven reliability in audio and power electronics, and sufficient noise/speed for commercial-grade signal conditioning - making it the default choice unless extended temperature or ultra-low-noise requirements apply.

FAQ
What is the maximum capacitive load the TL074CPWR can drive stably?
The TL074CPWR is characterized to drive up to 300 pF capacitive load while maintaining phase margin ≥56° and settling time ≤0.91 μs (to 0.01%). For loads >300 pF, external isolation resistor (e.g., 10–100 Ω) between output and capacitance is recommended to prevent peaking or oscillation - verified in TI's SLOS080W datasheet Section 5.7.
Does the TL074CPWR support single-supply operation?
Yes, the TL074CPWR supports single-supply operation from 4.5 V to 40 V (e.g., 5 V, 12 V, 24 V). Its common-mode input range extends to VCC+, allowing input signals referenced to ground or mid-rail. However, output swing is limited to ~210 mV from each rail under 40 V supply, so proper biasing (e.g., VCM = VCC+/2) is required for AC-coupled signals.
How does the TL074CPWR differ from the TL074H variant?
The TL074CPWR uses the legacy "C" grade silicon (0°C to 70°C), while TL074H employs newer "H"-grade die with improved specs: 1 mV offset (vs. 3 mV typ for C), 37 nV/√Hz noise (same), and extended –40°C to +125°C operation. Both share identical pinout and TSSOP-14 packaging, but TL074H is preferred for automotive or harsh-environment use.
Is the TL074CPWR pin-compatible with other quad op-amps like LM324?
No - the TL074CPWR uses standard quad op-amp pinout (14-pin TSSOP: 1OUT, 1IN–, 1IN+, VCC+, 2IN+, 2IN–, 2OUT, VCC–, 3OUT, 3IN+, VCC–, 3IN–, 4IN–, 4OUT), which matches LM324, LM348, and RC4136. However, LM324 is bipolar-input with higher noise (40 nV/√Hz) and lower slew rate (0.5 V/μs); direct substitution requires verifying input bias, noise, and speed requirements.
What is the ESD rating of the TL074CPWR?
The TL074CPWR has a Human-Body Model (HBM) ESD rating of ±2000 V and Charged-Device Model (CDM) rating of ±1000 V, per JEDEC JS-001 and JESD22-C101 standards. These ratings reflect built-in protection diodes and layout hardening, enabling robust handling in automated assembly and field service without additional external protection.
