Product details
Overview
TL074CNSR 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 TL074CNSR datasheet, TL074CNSR pinout, TL074CNSR application, or TL074CNSR equivalent, key selection criteria include its FET-input architecture for ultra-low bias current (≤120 pA typ), quad-channel integration in SOP-14 package, guaranteed 0–70°C operating range (TL074C grade), and compatibility with single- or dual-supply configurations up to 40 V total.
Technical Context
The TL074CNSR employs a JFET differential input stage enabling femtoampere-level input bias currents and high input impedance (>1 TΩ). Its internal compensation ensures unity-gain stability with capacitive loads up to 300 pF, while the output stage provides symmetrical sourcing/sinking capability and short-circuit protection.
Designed for cost-sensitive analog signal chains, it supports wide supply ranges (±2.25 V to ±20 V or 4.5 V to 40 V) and features integrated EMI filtering. The device operates across 0°C to 70°C ambient temperature and exhibits 2 μV/°C offset drift and 100 dB typical CMRR at DC.
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 slew-induced distortion |
| Input Voltage Noise | 37 nV/√Hz at 1 kHz - critical for low-level sensor amplification and high-fidelity audio front-ends |
| Input Bias Current | ≤120 pA (typ) - preserves signal integrity in high-impedance source applications like photodiode or piezoelectric interfaces |
| Common-Mode Input Range | Includes VCC+ - allows direct sensing of signals referenced to positive rail, simplifying level-shifting circuits |
| Supply Voltage Range | ±2.25 V to ±20 V (or 4.5 V to 40 V) - supports both low-voltage portable and high-voltage industrial power domains |
| Offset Voltage Drift | ±2 μV/°C - ensures stable DC accuracy over temperature in precision instrumentation and calibration systems |
| Quiescent Current | 1.4–2.5 mA per amplifier - balances low-power operation with high-speed performance in multi-channel designs |
Pinout & Package
TL074CNSR is housed in a 14-pin SOP (Small Outline Package) with standard JEDEC MS-012AC footprint and 1.27 mm pitch. The package is surface-mount, RoHS-compliant, and rated for reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of first op-amp channel - drives external load or next stage with rail-to-rail swing capability |
| 2 | 1IN− | Inverting input of first op-amp - accepts feedback or inverted signal path in active filters or comparators |
| 3 | 1IN+ | Noninverting input of first op-amp - connects to reference, sensor, or signal source with minimal loading |
| 4 | VCC+ | Positive power supply terminal - must be decoupled locally to suppress supply noise coupling into all four amplifiers |
| 5 | 2IN+ | Noninverting input of second op-amp - electrically isolated from other channels but shares VCC+/VCC− rails |
| 6 | 2IN− | Inverting input of second op-amp - used for differential gain stages or active summing configurations |
| 7 | 2OUT | Output of second op-amp - independent output node supporting separate signal paths within same IC |
| 8 | VCC− | Negative power supply terminal - return path for all four amplifiers; requires low-impedance ground plane |
| 9 | 3OUT | Output of third op-amp - enables compact multi-stage architectures (e.g., preamp + filter + driver) |
| 10 | 3IN+ | Noninverting input of third op-amp - supports cascaded or parallel channel configurations |
| 11 | VCC− | Shared negative supply - not a dedicated pin; pin 8 serves as sole VCC− connection for all channels |
| 12 | 3IN− | Inverting input of third op-amp - used in instrumentation amplifier topologies or active integrators |
| 13 | 4IN− | Inverting input of fourth op-amp - completes full quad functionality for complex analog processing |
| 14 | 4OUT | Output of fourth op-amp - final stage output; may drive ADC input, LED driver, or comparator reference |

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 electrical specs and pinout; SOIC-14 package instead of SOP-14 - identical thermal resistance (RθJA = 76°C/W) and moisture sensitivity level (MSL 3). | No functional difference; SOIC-14 offers wider availability and broader PCB assembly compatibility than SOP-14. | Select TL074CDR if board layout uses standard SOIC footprints or requires higher-volume manufacturing support. |
| RC4136N | Higher quiescent current (3.5 mA/ch), lower slew rate (10 V/μs), and no guaranteed VCC+-inclusive common-mode range - lacks rail-to-rail input capability. | Not suitable for high-speed or rail-referenced sensing; better suited for general-purpose DC-coupled amplification where speed and input range are secondary. | Choose RC4136N only when legacy design reuse mandates identical pinout and cost is primary constraint - verify input range and settling time margins. |
Compared with TL074CNSR, TL074CDR offers identical performance in a more widely adopted SOIC package, while RC4136N trades speed and input flexibility for marginally lower cost in non-critical analog functions.

FAQ
What is the maximum supply voltage rating for TL074CNSR?
The TL074CNSR supports a total supply voltage range of 4.5 V to 40 V (single-supply) or ±2.25 V to ±20 V (dual-supply). Absolute maximum ratings specify 42 V for non-NS/PS packages, but the recommended operating condition limits total VS to 40 V to ensure long-term reliability and specified performance across 0°C to 70°C ambient temperature.
Does TL074CNSR support rail-to-rail input operation?
Yes, TL074CNSR features a common-mode input voltage range that includes VCC+, enabling true rail-to-rail input operation on the positive side. Its input stage accepts signals up to the positive supply rail, which simplifies interfacing with high-side sensors and eliminates the need for external level-shifting networks in many applications.
What is the typical input offset voltage for TL074CNSR?
The TL074CNSR (C-grade) has a typical input offset voltage of 3 mV, with a maximum of 10 mV over the full 0°C to 70°C operating temperature range. This value is confirmed in Section 5.8 of the official TI datasheet for TL07xC devices under ±15 V supply conditions at TA = 25°C.
Can TL074CNSR drive capacitive loads reliably?
Yes, TL074CNSR is characterized to drive capacitive loads up to 300 pF while maintaining stability. Its internal compensation and 5.25 MHz gain-bandwidth product ensure controlled step response and minimal overshoot even with moderate capacitive loading - a key advantage over earlier-generation JFET op-amps.
Is TL074CNSR pin-compatible with other TL074 variants?
Yes, TL074CNSR is pin-compatible with all TL074x variants in the NS (SOP-14) package, including TL074CDR, TL074CN, and TL074ACNSR. Pin assignments, electrical behavior, and thermal characteristics are identical across C-grade NS-package devices, enabling drop-in replacement within the same package family.
