Product details
Overview
TL074BCDRG4 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 impedance and low distortion are critical.
For engineers reviewing the TL074BCDRG4 datasheet, TL074BCDRG4 pinout, TL074BCDRG4 application, or TL074BCDRG4 equivalent, key selection criteria include verified input offset drift (±2 μV/°C), confirmed capacitive load drive capability (300 pF), guaranteed output short-circuit protection, and documented EMI rejection ratio (53 dB at 1 GHz) - all specified for the TL074B grade in SOIC-14 package.
Technical Context
The TL074BCDRG4 implements a high-impedance JFET differential pair input stage with internal frequency compensation, enabling stable unity-gain operation without external components. Its architecture supports wide common-mode input range (including VCC+) and provides inherent output short-circuit protection across all four amplifiers.
It operates over 0°C to 70°C ambient temperature with supply voltages from ±2.25 V to ±20 V (or 4.5 V to 40 V single-ended), and features integrated EMI filtering and 2-kV HBM ESD protection - characteristics validated specifically for the TL074B variant per TI SLOS080W Rev. July 2025.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of first amplifier - directly drives downstream gain stages or ADC inputs |
| 2 | 1IN− | Inverting input of first amplifier - accepts feedback network for stable closed-loop configurations |
| 3 | 1IN+ | Noninverting input of first amplifier - connects to reference or sensor signal with high-impedance FET input |
| 4 | VCC+ | Positive supply rail - must be decoupled locally to minimize noise coupling between channels |
| 5 | 2IN+ | Noninverting input of second amplifier - electrically isolated from Channel 1 for multi-channel signal processing |
| 6 | 2IN− | Inverting input of second amplifier - supports independent feedback paths per channel |
| 7 | 2OUT | Output of second amplifier - shares same thermal and layout constraints as Channel 1 |
| 8 | VCC− | Negative supply rail - requires symmetrical decoupling to maintain PSRR performance |
| 9 | 3OUT | Output of third amplifier - enables three-stage active filtering or multi-path signal conditioning |
| 10 | 3IN+ | Noninverting input of third amplifier - maintains >1 TΩ input resistance for charge-sensitive applications |
| 11 | VCC− | Shared negative rail - pin 8 and pin 11 are internally connected in package; both must be routed |
| 12 | 3IN− | Inverting input of third amplifier - supports summing or differential configurations with low bias current error |
| 13 | 4IN− | Inverting input of fourth amplifier - enables simultaneous processing of four independent analog signals |

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 | Higher input offset voltage (3 mV typ vs. 1 mV typ for TL074B); wider offset drift (±18 μV/°C) | Less suitable for precision DC-coupled measurement; acceptable for AC-coupled audio | Select TL074CDR only when cost sensitivity outweighs DC accuracy requirements |
| OPA4134UA | Lower noise (8 nV/√Hz), lower distortion (0.00008%), but higher quiescent current (4 mA/ch) and no built-in short-circuit protection | Better for ultra-low-noise studio preamps; unsuitable for ruggedized industrial sensing | Choose OPA4134UA when ultimate audio fidelity is required and thermal/power budget allows |
Compared with TL074CDR, TL074BCDRG4 offers tighter DC specs and better thermal stability; compared with OPA4134UA, it trades some noise performance for robustness, lower power, and integrated protection - making it optimal for cost-constrained, high-reliability industrial signal chains.

FAQ
What is the maximum capacitive load the TL074BCDRG4 can drive while maintaining stability?
The TL074BCDRG4 is characterized to drive up to 300 pF capacitive load without oscillation or excessive overshoot, as verified in TI's SLOS080W datasheet Figure 5-23 and Figure 5-24. This specification applies under standard test conditions (G = +1, RL = 10 kΩ, CL = 20–300 pF). For loads exceeding 300 pF, external isolation resistors or compensation networks are required. The TL074BCDRG4's internal compensation is fixed and not user-adjustable.
Does the TL074BCDRG4 support single-supply operation?
Yes, the TL074BCDRG4 supports true single-supply operation from 4.5 V to 40 V, with common-mode input voltage range extending from (VCC−) + 1.5 V to VCC+. This allows direct interfacing with unipolar sensors and microcontroller ADC references without level-shifting circuitry. However, output swing remains limited to ~200 mV from each rail under load, so mid-supply biasing is recommended for AC-coupled applications.
How does the TL074BCDRG4 differ from the TL074H variant?
The TL074BCDRG4 is the commercial-grade (0°C to 70°C) version with tighter initial offset voltage (1 mV typ vs. 3 mV typ for TL074C) and lower offset drift (±2 μV/°C vs. ±18 μV/°C for TL074C), while the TL074H is the enhanced-performance variant rated for –40°C to +125°C with identical AC specs (20 V/μs, 37 nV/√Hz) but improved PSRR and CMRR. Both share the same SOIC-14 package and pinout, but TL074H adds integrated EMI filtering and 2-kV HBM ESD protection.
Is the TL074BCDRG4 pin-compatible with other TL074 variants in SOIC-14?
Yes, all TL074x variants in the D (SOIC-14) package - including TL074CDR, TL074ACDR, TL074BCDRG4, and TL074H - share identical pinout, footprint, and electrical connectivity per Table 4-6 of the TI datasheet. No PCB changes are required when upgrading from TL074CDR to TL074BCDRG4, though layout best practices (local decoupling, ground plane integrity) remain essential to realize the B-grade's improved DC performance.
What is the quiescent current per channel for the TL074BCDRG4?
The TL074BCDRG4 draws 937.5 µA to 1125 µA per amplifier at 25°C with no load, as specified in Section 5.7 of the TI SLOS080W datasheet. Total device quiescent current is therefore 3.75 mA to 4.5 mA. At full temperature range (0°C to 70°C), maximum per-channel current rises to 1130 µA, resulting in a worst-case total of 4.52 mA - well within low-power design budgets for multi-channel analog front-ends.
