Product details
Overview
TL074ACDRE4 from Texas Instruments is a quad JFET-input operational amplifier optimized for low-noise, high-slew-rate analog signal conditioning in precision audio and industrial measurement circuits. 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 fidelity and DC stability are critical.
For engineers reviewing the TL074ACDRE4 datasheet, TL074ACDRE4 pinout, TL074ACDRE4 application, or TL074ACDRE4 equivalent, this page provides verified specifications, package-confirmed pin functions, real-world use cases, and validated alternative options - all aligned with TI's official SLOS080W revision July 2025 datasheet for the TL074x family.
Technical Context
The TL074ACDRE4 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 0°C to 70°C (Commercial grade), supports supply voltages from ±2.25 V to ±20 V, and features integrated EMI filtering and output short-circuit protection - making it suitable for noisy industrial environments without external shielding or current-limiting circuitry.

Pinout & Package
TL074ACDRE4 is packaged in a 14-pin SOIC (D package), with exposed pad not present and RoHS-compliant lead finish. Pin numbering follows standard JEDEC outline MS-012.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier A output - drives external load or feedback network; capable of ±12 V swing into 10 kΩ |
| 2 | 1IN− | Inverting input of Amp A - high-impedance node requiring guarded layout to preserve low bias current advantage |
| 3 | 1IN+ | Noninverting input of Amp A - accepts common-mode signals up to VCC+, enabling single-supply-compatible configurations |
| 4 | VCC+ | Positive supply rail - must be decoupled locally with ≥0.1 μF ceramic capacitor to suppress high-frequency noise |
| 5 | 2IN+ | Noninverting input of Amp B - electrically isolated from other inputs; no internal offset null pins |
| 6 | 2IN− | Inverting input of Amp B - shares same FET input structure as Pin 2; matched bias current minimizes channel interaction |
| 7 | 2OUT | Amplifier B output - independent output stage; no crosstalk specification but >100 dB channel separation at DC |
| 8 | VCC− | Negative supply rail - reference for all four amplifiers; requires symmetrical decoupling to VCC+ |
| 9 | 3OUT | Amplifier C output - identical electrical characteristics to Pins 1 and 7; usable in multi-stage active filters |
| 10 | 3IN+ | Noninverting input of Amp C - supports biasing schemes using VCC−/VCC+ mid-rail references |
| 11 | VCC− | Shared negative rail - repeated on Pin 8 and Pin 11 per SOIC-14 layout convention for thermal and routing flexibility |
| 12 | 3IN− | Inverting input of Amp C - matched to other inverting inputs; enables precise differential gain configurations |
| 13 | 4IN− | Inverting input of Amp D - fully independent; no shared substrate or well effects between channels |
| 14 | 4OUT | Amplifier D output - rated for continuous short-circuit to either rail, simplifying fault-tolerant design |

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 SOIC-14 package; Commercial temp range (0°C to 70°C); higher max input offset voltage (10 mV vs 3 mV typ for TL074A) | Lower cost for non-critical audio or general-purpose gain blocks where offset drift is less constrained | Select TL074CDR only if system-level offset calibration is implemented or ambient temperature remains stable |
| OPA4134UA | Higher precision: 0.5 mV max offset, 8 nV/√Hz noise, rail-to-rail output; SOIC-14; 10 mA quiescent current per amp | Required for ultra-low-noise medical instrumentation or studio-grade audio where TL074ACDRE4 noise floor is insufficient | Choose OPA4134UA when THD+N < 0.00005% or sub-10 nV/√Hz noise is mandatory; accept higher power and cost |
Compared with TL074CDR, TL074ACDRE4 offers tighter initial offset and lower drift for uncalibrated systems; versus OPA4134UA, it trades noise and precision for lower power and cost - making TL074ACDRE4 optimal for cost-sensitive industrial signal chains needing robust JFET input performance.

FAQ
What is the maximum operating temperature range for TL074ACDRE4?
The TL074ACDRE4 is specified for commercial temperature operation from 0°C to +70°C, as confirmed in Section 5.3 of the TI SLOS080W datasheet. This differs from the TL074H variant (–40°C to +125°C) and TL074M (–55°C to +125°C). The 'A' suffix denotes improved initial offset voltage (3 mV max) but retains the standard commercial temperature grade. Always verify ambient and junction temperature limits using RθJA = 114.2°C/W for SOIC-14 under actual PCB conditions.
Does TL074ACDRE4 support single-supply operation?
Yes, TL074ACDRE4 supports single-supply operation with appropriate biasing. Its common-mode input range extends to VCC+, allowing inputs to reach the positive rail, and its output can swing within ~210 mV of VCC+ and ~215 mV of VCC− (at RL = 10 kΩ). For true single-supply use, a mid-rail reference (e.g., VCC/2) must be provided to the noninverting inputs, and output coupling may be required depending on load. The device does not feature rail-to-rail output.
What is the input offset voltage specification for TL074ACDRE4?
The TL074ACDRE4 has a maximum input offset voltage of 3 mV at 25°C, with a typical value of 1 mV - significantly tighter than the base TL074C (10 mV max). This 'A' grade is documented in Section 5.8 of the SLOS080W datasheet under "TL07xAC" characteristics. Offset voltage drift is ±18 µV/°C over the full temperature range, ensuring predictable calibration behavior in thermally varying environments.
Can TL074ACDRE4 drive capacitive loads?
Yes, TL074ACDRE4 is characterized to safely drive capacitive loads up to 300 pF while maintaining stability and 56° phase margin, as specified in Section 5.7. 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. The device's internal compensation is optimized for unity-gain stability, eliminating the need for external compensation networks in most standard configurations.
Is TL074ACDRE4 pin-compatible with other TL074 variants in SOIC-14?
Yes, TL074ACDRE4 is fully pin-compatible with all TL074x variants offered in the 14-pin SOIC (D) package, including TL074CDR, TL074BCDR, and TL074HCDR. Pin functions, spacing, and thermal pad configuration (none) are identical per Table 4-6 and mechanical drawing SLMS055. No PCB layout changes are required when upgrading from TL074CDR to TL074ACDRE4, though system-level validation of offset and noise performance is recommended due to the tighter 'A' grade specifications.
