Product details
Overview
TL074BCNSRG4 from Texas Instruments is a quad JFET-input operational amplifier optimized for low-noise, high-slew-rate signal conditioning in precision analog systems. It delivers 20 V/μs slew rate, 37 nV/√Hz input voltage noise at 1 kHz, ±1 mV typical input offset voltage, and operates from ±2.25 V to ±20 V supplies. It is used in pro audio mixers and battery test equipment where wide common-mode range (including VCC+) and low distortion (0.003% THD+N) are critical.
For engineers reviewing the TL074BCNSRG4 datasheet, TL074BCNSRG4 pinout, TL074BCNSRG4 application, or TL074BCNSRG4 equivalent, this page provides verified package mapping (14-pin SOIC-NS), confirmed quad-channel FET-input architecture, validated rail-to-rail-compatible input stage, and two industry-recognized alternative parts with documented functional alignment and key parameter trade-offs.
Technical Context
The TL074BCNSRG4 implements a high-impedance JFET differential pair input stage enabling ultra-low input bias current (±1 pA typ) and low input capacitance (6 || 1 TΩ || pF). Its internal compensation ensures unity-gain stability with ≥56° phase margin and 5.25 MHz gain-bandwidth product.
It supports single-supply operation via extended common-mode input range (VCM includes VCC+), features output short-circuit protection, and integrates EMI/RF filters for robustness in electrically noisy environments such as motor drive power stages and UPS inverters.

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 quad JFET architecture but C-grade (0°C to 70°C), higher 3 mV max offset, 37 nV/√Hz noise unchanged | Targeted at commercial-grade audio and general-purpose analog circuits without extended temp requirement | Select when cost sensitivity outweighs industrial temperature range or ultra-low offset needs |
| OPA4134UA | Lower 0.5 mV max offset, lower 8 nV/√Hz noise, higher 10 MHz GBW, but 2.5 mA/ch quiescent current vs 0.94 mA | Preferred in high-end audio DAC output stages and precision data acquisition where noise and offset dominate power budget | Select when ultimate DC precision and wide bandwidth justify higher supply current and cost |
Compared with TL074CDR, TL074BCNSRG4 offers tighter offset and extended temperature range; compared with OPA4134UA, it trades lower noise and offset for significantly reduced quiescent current and broader supply flexibility-making it optimal for multi-channel industrial signal chains where thermal and power constraints apply.

FAQ
What is the maximum operating temperature range for TL074BCNSRG4?
The TL074BCNSRG4 is rated for operation from –40°C to +125°C, matching the TL074H specification tier. This extended temperature capability is confirmed in Section 5.3 of the TI datasheet and enables use in industrial motor drives and outdoor solar inverters where ambient temperatures exceed commercial-grade limits. The device maintains its 20 V/μs slew rate and 37 nV/√Hz noise performance across this full range.
Does TL074BCNSRG4 support single-supply operation?
Yes, TL074BCNSRG4 supports true single-supply operation with a common-mode input voltage range that includes the positive supply rail (VCC+). As specified in Table 5.7, VCM extends from (VCC–) + 1.5 V to VCC+, allowing direct interfacing with sensors or signals referenced to VCC+. For example, with VCC+ = 12 V and VCC– = 0 V, valid input voltages span 1.5 V to 12 V-enabling high-side current sensing without level-shifting circuitry.
What is the output drive capability of TL074BCNSRG4?
TL074BCNSRG4 delivers ±26 mA short-circuit output current per channel and sustains stable operation into capacitive loads up to 300 pF. Its output voltage swing reaches within 210 mV of VCC+ and 215 mV of VCC– (at VS = 40 V, RL = 10 kΩ), providing >11 V peak-to-peak swing in ±15 V systems. This drive strength supports direct connection to ADC drivers, LED bias circuits, and moderate-current transducer interfaces without external buffers.
How does TL074BCNSRG4 compare to TL074CP in terms of noise performance?
TL074BCNSRG4 and TL074CP both specify 37 nV/√Hz input voltage noise density at 1 kHz, as confirmed in Sections 5.7 and 5.9 of the TI datasheet. However, TL074BCNSRG4 (H-grade) exhibits lower 1/f noise-1.4 µVRMS over 0.1 Hz to 10 Hz-versus 4 µVRMS for TL074CP (C-grade)-making it superior for DC-coupled, low-frequency instrumentation where flicker noise dominates. Both share identical spectral noise shape above 10 Hz.
Is TL074BCNSRG4 pin-compatible with other TL074 variants in SOIC-14 packages?
Yes, TL074BCNSRG4 uses the standard 14-pin SOIC-NS footprint defined in Table 4-6 and Figure 4-8, matching all TL074x variants in D, N, NS, and PW packages. Pin functions-including VCC+, VCC−, and all four IN+/IN−/OUT assignments-are identical across these variants. This allows drop-in replacement in existing layouts designed for TL074CDR, TL074CN, or TL074IDR, provided thermal and electrical validation confirms suitability for the H-grade's extended temperature and tighter offset specifications.
