Product details
Overview
TL074BCNSRE4 from Texas Instruments is a quad-channel, JFET-input operational amplifier optimized for low-noise audio and precision analog signal conditioning. 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, 118 dB open-loop gain, 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 TL074BCNSRE4 datasheet, TL074BCNSRE4 pinout, TL074BCNSRE4 application, or TL074BCNSRE4 equivalent, this page provides verified electrical specifications, package-validated pin functions, real-world use cases, and two confirmed alternative parts with documented technical and application differences - all derived from TI's official SLOS080W datasheet (Rev. July 2025).
Technical Context
The TL074BCNSRE4 implements a high-slew-rate, low-noise JFET-input differential pair with internal frequency compensation, enabling stable unity-gain operation. Its input stage features ultra-low bias current (±1 pA typ) and low offset drift (±2 µV/°C), supporting precision DC-coupled designs across –40°C to +125°C.
It supports wide supply ranges (±2.25 V to ±20 V), includes output short-circuit protection, and achieves 0.00012% THD+N at 1 kHz - making it suitable for high-fidelity signal paths where harmonic integrity and EMI immunity (53 dB EMIRR at 1 GHz) are essential.

FAQ
What is the maximum operating temperature range for TL074BCNSRE4?
The TL074BCNSRE4 is specified for operation from –40°C to +125°C, matching the TL074H grade per TI's SLOS080W datasheet (Rev. July 2025). This extended temperature range supports deployment in harsh environments such as solar inverters and industrial motor drives where ambient temperatures exceed commercial limits.
Does TL074BCNSRE4 support single-supply operation?
Yes, TL074BCNSRE4 supports single-supply operation from 4.5 V to 40 V. Its common-mode input range extends to VCC+, allowing inputs to swing up to the positive rail - a key advantage for single-supply sensor interfaces and battery-powered instrumentation where rail-to-rail input capability is required.
What is the input bias current specification for TL074BCNSRE4?
The TL074BCNSRE4 has a typical input bias current of ±1 pA at 25°C, with a maximum of ±120 pA over temperature (–40°C to +125°C). This ultra-low bias current is enabled by its JFET input stage and makes TL074BCNSRE4 ideal for high-impedance applications like photodiode amplifiers and precision integrators.
How does TL074BCNSRE4 differ from the standard TL074CP?
TL074BCNSRE4 is a TL074H-grade device in NS (SOIC) packaging, featuring improved specs over TL074CP: lower offset voltage (±1 mV typ vs ±3 mV), lower noise (37 nV/√Hz vs 18 nV/√Hz for PS/NS variants), higher ESD rating (±2000 V HBM), and guaranteed operation to +125°C - whereas TL074CP is C-grade (0°C to 70°C) with looser tolerances.
Is TL074BCNSRE4 pin-compatible with other TL074 variants in SOIC-14 packages?
Yes, TL074BCNSRE4 uses the industry-standard 14-pin SOIC (NS) footprint and shares identical pinout with all TL074x devices in D, NS, and PW packages per Table 4-6 of the datasheet - ensuring drop-in compatibility for layout reuse across TL074H, TL074C, and TL074I variants in the same package form factor.
