Product details
Overview
TL074CD from STMicroelectronics is a low-noise JFET-input quad operational amplifier in SO14 package, featuring 16 V/µs typical slew rate, 15 nV/√Hz input voltage noise, ±15 V common-mode input range, and 2 MHz gain-bandwidth product. It serves as a precision analog signal conditioner in audio distribution, active filter, and sensor interface circuits operating from ±5 V to ±18 V supplies.
For engineers reviewing the TL074CD datasheet, TL074CD pinout, TL074CD application, or TL074CD equivalent, key selection criteria include input bias current (≤30 pA), output short-circuit protection, JFET input stage high impedance (10¹² Ω), and guaranteed operation from 0°C to +70°C ambient temperature.
Technical Context
The TL074CD integrates four matched JFET-input op-amps on a single monolithic die with internal frequency compensation and latch-up-free bipolar-JFET hybrid process. Each amplifier supports rail-to-rail common-mode input up to ±15 V and delivers ±12 V output swing into 2 kΩ load at ±15 V supply.
Its architecture enables low harmonic distortion (0.01% THD at 1 kHz) and high CMRR (70 dB min) across temperature, making it suitable for AC-coupled instrumentation and multi-stage audio signal chains where channel separation (120 dB) and noise performance are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±5 V to ±18 V - supports dual-rail analog systems including legacy ±12 V and ±15 V designs |
| Slew Rate | 13 V/µs (typ) - enables faithful reproduction of audio signals up to ~200 kHz without slew-induced distortion |
| Input Noise | 15 nV/√Hz (typ, 1 kHz) - preserves SNR in low-level microphone preamp and sensor front-end stages |
| Input Bias Current | 30 pA (max, +25°C) - minimizes DC error in high-impedance transducer interfaces (e.g., piezoelectric sensors) |
| Gain-Bandwidth | 2 MHz (typ) - sufficient for unity-gain stable audio filters and 20× closed-loop amplification up to 100 kHz |
| CMRR | 70 dB (min) - rejects power-supply ripple and shared ground noise in multi-amplifier PCB layouts |
| Output Short-Circuit | Infinite duration - allows safe use in test fixtures and prototyping without external current limiting |
Pinout & Package
TL074CD is housed in a 14-pin SOIC (SO14) plastic micropackage with 1.27 mm pitch, 8.75 mm length, and 4.0 mm width - compatible with standard surface-mount reflow profiles and automated assembly.

| 12 | Non-inverting Input D | Non-inverting node for Amp D - enables four independent gain blocks or one 4-pole filter |
| 13 | Inverting Input D | Inverting node for Amp D - matched offset and drift for precision summing applications |
| 14 | Output D | Amplifier D output - fully specified for ±12 V swing into 2 kΩ at +25°C |
Key Features

Use Value: Matched amplifier parameters across all four sections reduce inter-stage offset accumulation and thermal drift. |
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 |
|---|---|---|---|
| TL084CD | Higher input noise (18 nV/√Hz), faster slew rate (13 V/µs → 16 V/µs), same SO14 package | Less suitable for ultra-low-noise mic preamps; better for wideband pulse amplification | Choose TL084CD when bandwidth >2.5 MHz is required and noise floor is secondary |
| RC4136N | Lower input bias current (10 pA typ), wider supply range (±4 V to ±22 V), DIP-14 only | Not surface-mount compatible; requires through-hole assembly and larger board area | Choose RC4136N only for legacy through-hole designs needing sub-20 pA bias performance |
Compared with TL074CD, TL084CD trades 3 nV/√Hz higher noise for marginally improved speed, while RC4136N offers lower bias current but sacrifices SMT compatibility and modern thermal performance - TL074CD remains optimal for cost-sensitive, noise-conscious SMT audio and sensor systems.

FAQ
What is the maximum operating temperature for TL074CD?
The TL074CD is rated for 0°C to +70°C free-air operating temperature. This commercial-grade specification reflects its intended use in non-automotive, non-industrial harsh-environment applications such as consumer audio equipment and office instrumentation where ambient conditions remain controlled.
Does TL074CD require external compensation capacitors?
No - TL074CD features internal frequency compensation optimized for unity-gain stability. External compensation is unnecessary in standard inverting, non-inverting, and voltage-follower configurations. Only specialized high-Q filter or high-gain (>100×) applications may benefit from optional external compensation to fine-tune phase margin.
Can TL074CD drive capacitive loads directly?
TL074CD can safely drive ≤100 pF capacitive loads without oscillation. For larger loads (e.g., cables or ADC input capacitance), a 100 Ω isolation resistor should be placed in series with the output to maintain stability. This limitation arises from its internal compensation topology, not output current capability.
How does TL074CD differ from TL074CP?
TL074CD uses SO14 surface-mount packaging, while TL074CP uses 14-pin PDIP through-hole packaging. Both share identical electrical specifications and temperature range (0°C to +70°C), but CD supports automated SMT assembly and offers superior thermal resistance (105°C/W vs. ~65°C/W for PDIP), making it preferred for compact, high-density PCBs.
