Texas Instruments TL084ACNSR

Overview

TL084ACNSR from Texas Instruments is a quad JFET-input operational amplifier optimized for precision AC/DC signal conditioning in industrial and audio systems. It delivers 5.25 MHz gain-bandwidth, 20 V/μs slew rate, ±1 mV input offset voltage (typ), 105 dB CMRR, and operates from ±2.25 V to ±20 V supply rails. It is used in pro audio mixers and battery test equipment where low noise and rail-to-rail common-mode input range are critical.

For engineers reviewing the TL084ACNSR datasheet, TL084ACNSR pinout, TL084ACNSR application, or TL084ACNSR equivalent, key selection criteria include its FET-input architecture for ultra-low bias current (1 pA typ), wide supply flexibility, integrated EMI filtering, and guaranteed operation from –40°C to 85°C - essential for high-fidelity analog front-ends and rugged instrumentation.

Technical Context

The TL084ACNSR implements a high-speed JFET differential input stage with internal compensation, enabling stable unity-gain operation without external components. Its input stage includes integrated EMI/RF filters and supports common-mode voltage up to VCC+, eliminating level-shifting requirements in single-supply configurations.

It features output short-circuit protection and exhibits low total harmonic distortion (0.003% typ at 1 kHz), making it suitable for closed-loop precision amplification and active filter stages where linearity and settling time (0.56 μs to 0.1%) are design-critical.

Key Specifications

Pinout & Package

FAQ

What is the operating temperature range of TL084ACNSR?

The TL084ACNSR is specified for operation from –40°C to +85°C. This industrial temperature grade ensures reliable performance in motor drives, solar inverters, and battery test equipment exposed to ambient thermal stress. All electrical characteristics - including offset voltage drift (±2 µV/°C) and CMRR - are guaranteed across this full range, unlike commercial-grade variants such as TL084CDR.

Does TL084ACNSR support single-supply operation?

Yes, TL084ACNSR supports true single-supply operation due to its common-mode input voltage range extending to VCC+. When powered from +5 V to +40 V (with VCC– grounded), inputs can accept signals up to the positive rail. However, output swing remains limited to ~105–215 mV from each rail, so mid-rail biasing is recommended for AC-coupled applications.

What is the maximum capacitive load TL084ACNSR can drive stably?

TL084ACNSR is characterized to drive up to 300 pF capacitive load while maintaining stability and specified phase margin (56°). For loads exceeding 300 pF, external isolation resistance (e.g., 10–100 Ω in series with output) is recommended to prevent peaking or oscillation - especially critical in ADC driver and filter applications where signal integrity is paramount.

How does TL084ACNSR differ from TL084H variants?

TL084ACNSR belongs to the TL084A grade (–40°C to +85°C, ±1 mV offset typ), while TL084H denotes the high-reliability variant with tighter offset (±1 mV max), lower drift (±2 µV/°C), and enhanced ESD rating (1.5 kV HBM). TL084ACNSR uses the NS (SOIC-14) package; TL084H is commonly offered in D (SOIC-14) or PW (TSSOP-14), but functional specs align closely within their respective grades.

Is TL084ACNSR pin-compatible with other TL084 variants in SOIC-14?

Yes, TL084ACNSR is fully pin-compatible with all TL084x variants packaged in 14-pin SOIC (including TL084CDR, TL084IDR, and TL084BCDR), sharing identical pinout, footprint, and thermal pad configuration. This allows direct substitution in existing designs when upgrading to the A-grade's improved offset and temperature performance without PCB revision.
