Texas Instruments TL074BCNSR

Overview

TL074BCNSR from Texas Instruments is a quad JFET-input operational amplifier optimized for low-noise, high-slew-rate signal conditioning in audio and precision analog 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 FET-input stability and low distortion (0.003% THD+N) are critical.

For engineers reviewing the TL074BCNSR datasheet, TL074BCNSR pinout, TL074BCNSR application, or TL074BCNSR equivalent, key selection criteria include its quad-channel SOIC-14 package, guaranteed 1 mV max offset voltage (TL074H variant), 5.25 MHz gain-bandwidth product, and compatibility with ±15 V industrial supply rails and single-supply 4.5–40 V configurations.

Technical Context

The TL074BCNSR implements a JFET-input differential pair with high-impedance, low-bias-current front-end (±1 pA typ), enabling wide common-mode range including VCC+ and low input current drift. Its internal compensation ensures unity-gain stability with 56° phase margin and 0.48 μs settling time to 0.01% for 2-V steps.

It features integrated EMI/RF filters and 2-kV HBM ESD protection, supporting operation across –40°C to +125°C. The device uses TI's modern TL07xH die, distinguishing it from legacy TL07xC variants by tighter offset (±1 mV typ), lower noise, and improved PSRR (±1 μV/V).

Key Specifications

Pinout & Package

FAQ

What is the maximum supply voltage rating for TL074BCNSR?

The TL074BCNSR supports a total supply voltage (VCC+ to VCC−) of up to 40 V in single-supply mode or ±20 V in dual-supply mode. Absolute maximum ratings specify 36 V for NS-package devices; operation beyond 40 V risks permanent damage. Designers should maintain recommended operating conditions of 4.5 V to 40 V for reliable performance across temperature.

Does TL074BCNSR have rail-to-rail input or output capability?

TL074BCNSR features rail-to-rail common-mode input range-including VCC+-but does not provide rail-to-rail output swing. Its output typically swings to within 115–210 mV of each rail under 10-kΩ load. For true rail-to-rail output, consider alternatives like OPA4340 or TLV2464, though those lack the JFET input's ultra-low bias current.

How does the 'B' suffix in TL074BCNSR affect its specifications?

The 'B' suffix denotes the TL074H variant-TI's enhanced-performance version with tighter initial offset (±1 mV typ), lower input voltage noise (37 nV/√Hz), and guaranteed operation from –40°C to +125°C. It uses a modern die process distinct from older TL074C ('C') or TL074A ('A') grades, and is not a temperature-grade indicator alone.

Can TL074BCNSR drive capacitive loads reliably?

TL074BCNSR is characterized for stable operation with up to 300 pF capacitive load. Beyond that, phase margin degrades-observed as overshoot or ringing. For >300 pF loads (e.g., long cables or ADC input capacitance), add a small series resistor (10–100 Ω) between output and load to isolate capacitance and restore stability without compromising bandwidth significantly.

Is TL074BCNSR pin-compatible with other TL074 variants in SOIC-14?

Yes-TL074BCNSR is fully pin-compatible with all TL074x variants in the NS (SOIC-14) package, including TL074CDR, TL074ACDR, and TL074IDR. Pin functions, spacing, and thermal pad configuration (none) match exactly, enabling drop-in replacement where electrical specs meet system requirements.
