Product details
Overview
TL074BCDR from Texas Instruments is a quad-channel, JFET-input operational amplifier optimized for low-noise audio and precision analog signal conditioning. 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 high fidelity and DC accuracy are critical.
For engineers reviewing the TL074BCDR datasheet, TL074BCDR pinout, TL074BCDR application, or TL074BCDR equivalent, this page provides verified specifications, package-validated pin functions, real-world use cases, and two confirmed alternative parts with documented technical and application differences - all aligned to the TL074BCDR's C-grade temperature range (0°C to 70°C) and SOIC-14 package.
Technical Context
The TL074BCDR uses a high-impedance JFET differential input stage enabling ultra-low input bias current (≤200 pA typical) and low offset voltage drift (±18 µV/°C). Its internal compensation ensures stable unity-gain operation with ≤20 pF capacitive load, and its EMI-hardened design includes integrated RF filters for robustness in noisy industrial environments.
It operates across ±2.25 V to ±20 V supplies, supports common-mode inputs up to VCC+, and features output short-circuit protection. The device meets JEDEC JESD22-A114 HBM ESD rating of ±2000 V, making it suitable for assembly in standard electrostatic-controlled production lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables four independent gain stages or multi-stage filtering in single-package space-constrained designs |
| Slew Rate | 20 V/μs - supports clean amplification of audio-band signals up to ~300 kHz without slew-induced distortion |
| Input Voltage Noise | 37 nV/√Hz @ 1 kHz - preserves signal integrity in low-level sensor and microphone preamp circuits |
| Input Bias Current | 65–200 pA - minimizes voltage error in high-impedance feedback networks (e.g., >1 MΩ) |
| Supply Voltage Range | ±2.25 V to ±20 V - accommodates both low-voltage portable systems and high-dynamic-range industrial supplies |
| Offset Voltage Drift | ±18 µV/°C - ensures <1 mV total drift over 0°C–70°C operating range, critical for precision DC-coupled instrumentation |
| Common-Mode Input Range | Includes VCC+ - allows direct interface to sensors referenced to positive rail (e.g., current-sense amps) |
Pinout & Package
TL074BCDR is housed in a 14-pin SOIC (D) package with standard JEDEC MS-012AC footprint (5.3 mm × 10.2 mm, 1.27 mm pitch). Pin functions are validated per TI SLOS080W Rev. July 2025, Figure 4-8 and Table 4-6.

| 10 | 3IN+ | Noninverting input for Amplifier C - supports DC-coupled summing configurations |
| 11 | VCC− | Negative supply rail - return path for quiescent current (937.5–1125 µA per channel) |
| 12 | 4IN+ | Noninverting input for Amplifier D - enables four-channel active filtering or simultaneous signal conditioning |
| 13 | 4IN− | Inverting input for Amplifier D - fully specified for AC/DC performance across full temperature range |
| 14 | 4OUT | Amplifier D output - rated for 300 pF capacitive load stability without external compensation |
Key Features
| Feature | Design Value |
|---|---|

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 and pinout; wider offset voltage spec (3–10 mV vs. TL074BCDR's 2–3 mV max), identical noise and slew rate | Acceptable in non-critical audio or general-purpose gain blocks where tighter offset isn't required | Select TL074CDR for cost-sensitive designs where 3 mV max offset is sufficient and extended temp range not needed |
| OPA2134UA/2K5 | Lower noise (8 nV/√Hz), lower distortion (0.00008% THD+N), but higher quiescent current (4 mA/ch) and narrower supply (±4.5 V to ±18 V) | Better suited for ultra-high-fidelity audio paths; less suitable for battery-powered or thermally constrained systems | Choose OPA2134UA/2K5 only when sub-10 nV/√Hz noise and <0.0001% THD+N are mandatory, and power budget allows |
Compared with TL074CDR, TL074BCDR offers tighter initial offset for improved DC accuracy in sensor front-ends; compared with OPA2134UA/2K5, it trades noise performance for lower power and broader supply flexibility - making TL074BCDR optimal for cost-effective, thermally constrained, wide-supply industrial signal chains.

FAQ
What is the maximum capacitive load the TL074BCDR can drive stably?
The TL074BCDR is characterized for stable operation with up to 300 pF capacitive load without external compensation, as confirmed in TI SLOS080W Section 5.7. This enables direct driving of ADC input capacitors or long cables in battery test fixtures without oscillation risk. For loads exceeding 300 pF, a series resistor (typically 22–100 Ω) should be added at the output to isolate capacitance.
Does the TL074BCDR support single-supply operation?
Yes - the TL074BCDR supports single-supply operation from 4.5 V to 40 V, with common-mode input range extending to VCC+ and output swing within 210 mV of the positive rail (at RL = 10 kΩ). This allows use in 5 V or 12 V systems when biased at mid-supply using precision resistive dividers and decoupling.
What is the guaranteed input offset voltage specification for TL074BCDR?
The TL074BCDR has a maximum input offset voltage of 3 mV at 25°C and full temperature range (0°C to 70°C), per TI SLOS080W Section 5.8. This is tighter than the TL074CDR (max 10 mV), making TL074BCDR preferred for DC-coupled applications like precision current sensing where initial offset directly impacts measurement accuracy.
How does the EMI rejection performance of TL074BCDR compare to standard bipolar op-amps?
The TL074BCDR achieves 53 dB EMI rejection ratio at 1 GHz due to integrated RF filters - significantly higher than legacy bipolar op-amps (typically 20–30 dB). This is validated in Section 5.7 and enables reliable operation near switching power supplies or wireless modules without additional shielding or ferrite beads in pro audio or solar inverter designs.
Is the TL074BCDR pin-compatible with other TL074 variants in SOIC-14 package?
Yes - all TL074x variants (including TL074ACDR, TL074BCDR, TL074CDR, TL074HCDR) share identical pinout, SOIC-14 footprint, and electrical connectivity per TI SLOS080W Table 4-6. Substituting TL074BCDR for TL074CDR requires no PCB changes, though system-level validation of offset and drift behavior is recommended for precision applications.
