Product details
Overview
TL074CDRG4 from Texas Instruments is a quad JFET-input operational amplifier optimized for low-noise, high-slew-rate analog signal conditioning in industrial and audio 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, and rail-to-rail common-mode input range extending to VCC+. It is used in pro audio mixers and battery test equipment where precision DC performance and wide bandwidth are required.
For engineers reviewing the TL074CDRG4 datasheet, TL074CDRG4 pinout, TL074CDRG4 application, or TL074CDRG4 equivalent, this page provides verified package mapping (SOIC-14), confirmed quad-channel FET-input architecture, validated electrical specs including offset drift (±2 μV/°C), noise density, and supply range - all specific to the TL074C grade and DRG4 tape-and-reel variant.
Technical Context
The TL074CDRG4 implements a high-impedance JFET differential input stage followed by a Class AB output stage, enabling low input bias current (≤200 pA) and high open-loop gain (≥100 dB). Its internal compensation ensures unity-gain stability with capacitive loads up to 300 pF.
It operates across 0°C to 70°C ambient temperature with ±15 V nominal supply, supports common-mode input voltages from (VCC–) + 1.5 V to VCC+, and features output short-circuit protection. The device is not rail-to-rail output but achieves ±12 V swing into 10 kΩ at ±15 V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 20 V/μs - enables faithful reproduction of fast transients in audio and control loops without distortion |
| Input Voltage Noise | 37 nV/√Hz at 1 kHz - critical for low-level sensor amplification and high-fidelity audio front-ends |
| Input Offset Voltage | 3 mV max (typ 10 mV) - defines DC accuracy in precision instrumentation and feedback networks |
| Common-Mode Input Range | Extends to VCC+ - allows direct sensing of signals referenced to positive rail, e.g., current-sense in high-side configurations |
| Supply Voltage Range | ±2.25 V to ±20 V (4.5 V to 40 V single-ended) - supports flexible power architectures from low-voltage portable to industrial ±15 V systems |
| Quiescent Current | 1.4 mA per amplifier - balances low-power operation with performance in multi-channel designs |
| Gain-Bandwidth Product | 3 MHz - sets usable closed-loop bandwidth for stable gain ≥10 configurations |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of first op-amp channel - drives external load or next stage with ±12 V swing into 10 kΩ |
| 2 | 1IN– | Inverting input of first channel - connects to feedback network in inverting amplifier or summing junction |
| 3 | 1IN+ | Noninverting input of first channel - accepts reference, sensor, or signal source with >1 TΩ common-mode input resistance |
| 4 | VCC+ | Positive power supply terminal - must be decoupled locally with 0.1 μF ceramic capacitor |
| 5 | 2IN+ | Noninverting input of second channel - electrically isolated from other channels; shares no internal nodes |
| 6 | 2IN– | Inverting input of second channel - maintains same FET-input characteristics as Pin 2 |
| 7 | 2OUT | Output of second op-amp channel - independent output capable of sourcing/sinking ±26 mA short-circuit current |
| 8 | VCC– | Negative power supply terminal - return path for all four amplifiers; requires local decoupling |
| 9 | 3OUT | Output of third op-amp channel - identical AC/DC specs to Pins 1 and 7 |
| 10 | 3IN+ | Noninverting input of third channel - supports DC-coupled inputs up to VCC+ |
| 11 | VCC– | Shared negative supply rail - same node as Pin 8; no separate connection required |
| 12 | 3IN– | Inverting input of third channel - matched to other inverting inputs for consistent CMRR |
| 13 | 4IN– | Inverting input of fourth channel - fully independent; no crosstalk beyond specified 1 µV/V channel separation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad JFET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL074IPWR | Same TL074C die, TSSOP-14 package; 0.65 mm pitch, thinner profile, higher thermal resistance (RθJA = 200.3°C/W) | Preferred for space-constrained PCBs; requires tighter layout control for thermal management | Select when board area is limited and thermal derating is acceptable |
| RC4136N | Quad bipolar-input op-amp; higher input bias current (200 nA), lower noise (12 nV/√Hz), wider GBW (4 MHz), no VCC+-extended input | Better for low-noise, high-speed applications where input impedance >100 MΩ is not required | Choose for improved speed/noise trade-off in non-high-Z sensor interfaces |
Compared with TL074IPWR, TL074CDRG4 offers superior thermal performance in SOIC packaging and proven manufacturability in automated assembly; versus RC4136N, it provides 1000× lower input bias current essential for piezoelectric or photodiode front-ends, at the cost of slightly higher voltage noise.

FAQ
What is the maximum operating temperature range for TL074CDRG4?
The TL074CDRG4 is rated for operation from 0°C to +70°C ambient temperature, consistent with the TL074C grade. It is not qualified for extended industrial (–40°C to +85°C) or military (–55°C to +125°C) temperature ranges - those require TL074I or TL074M variants respectively.
Does TL074CDRG4 support rail-to-rail output swing?
No, TL074CDRG4 does not provide rail-to-rail output. At ±15 V supply and 10 kΩ load, its output swings to within approximately ±12 V of the rails - a headroom of ~3 V. This limitation must be accounted for in output stage design to avoid clipping.
Can TL074CDRG4 be used with single-supply operation?
Yes, TL074CDRG4 supports single-supply operation from 4.5 V to 40 V. Its common-mode input range extends to VCC+, enabling use with ground-referenced inputs when VCC– is tied to GND - a key advantage over many older op-amps that require input biasing.
What is the input offset voltage specification for TL074CDRG4?
The TL074CDRG4 has a maximum input offset voltage of 10 mV at 25°C, with typical value of 3 mV. Over the full 0°C to +70°C temperature range, offset drift is ±18 μV/°C, resulting in worst-case total offset of ~13 mV across temperature.
Is TL074CDRG4 pin-compatible with other TL074 variants like TL074CP or TL074CN?
Yes, TL074CDRG4 is pin-compatible with all TL074x variants in the 14-pin SOIC (D) package, including TL074CP (PDIP) and TL074CN (PDIP), provided the same package type is used. The DRG4 suffix denotes tape-and-reel packaging; electrical and pinout specifications are identical to TL074CD.
