Texas Instruments TL054CNSR

Overview

TL054CNSR from Texas Instruments is a quad FET-input operational amplifier optimized for precision analog signal conditioning in dual-supply systems. It delivers 4.5 MHz unity-gain bandwidth, 17.8 V/μs positive slew rate (±15 V), 10¹² Ω input resistance, <5.5 mV max input offset voltage (25°C), and 10.8 nV/√Hz input voltage noise at 1 kHz - enabling high-fidelity amplification of low-level sensor signals in test equipment and audio front-ends.

For engineers reviewing the TL054CNSR datasheet, TL054CNSR pinout, TL054CNSR application, or TL054CNSR equivalent, this page provides verified electrical specifications, SOIC-14 package details, real-world application contexts for instrumentation and signal chain design, and two validated alternative op-amps with documented functional trade-offs.

Technical Context

The TL054CNSR uses JFET-input stages to achieve ultra-low input bias current (≤100 pA at 25°C) and high DC precision via on-chip offset-voltage trimming. Its architecture maintains rail-to-rail output swing capability within ±11 V (at ±15 V supply) while preserving phase margin ≥60° at unity gain with 2 kΩ/25 pF load.

It operates across 0°C to 70°C (C-suffix), supports ±5 V and ±15 V dual supplies, and features 106 dB crosstalk attenuation between channels - critical for multi-channel data acquisition where inter-channel coupling must be minimized.

Key Specifications

Pinout & Package

TL054CNSR is housed in a 14-pin SOIC (Small Outline Integrated Circuit) package measuring 4.90 mm × 3.90 mm, with standard JEDEC MS-012AC footprint and 1.27 mm pitch. The package supports surface-mount reflow assembly and offers thermal impedance θ_JA = 86 °C/W.

FAQ

What is the maximum operating temperature range for TL054CNSR?

The TL054CNSR is rated for operation from 0°C to 70°C (C-suffix grade). This commercial temperature range is validated per TI's SLOS178B datasheet Section 4.3, and applies to all electrical characteristics unless otherwise noted. Operation outside this range may result in parametric degradation or functional failure.

Does TL054CNSR support single-supply operation?

TL054CNSR is designed for dual-supply operation (±5 V or ±15 V) and does not feature rail-to-rail input or output. Single-supply use requires external DC biasing of inputs to mid-rail and careful attention to common-mode input voltage limits (–1 V to +4 V at ±5 V supply). TI recommends LinCMOS TLC-series op-amps for native single-supply applications.

What is the typical input capacitance of TL054CNSR?

The typical input capacitance of TL054CNSR is 10 pF per input terminal, as specified in Section 4.4 of the SLOS178B datasheet. This value remains consistent across supply voltages (±5 V and ±15 V) and ambient temperatures (25°C), and impacts high-frequency stability when driving capacitive loads or using long PCB traces.

How does TL054CNSR compare to TL054ACNSR in offset voltage performance?

TL054CNSR has a maximum input offset voltage of 5.5 mV at 25°C, while TL054ACNSR improves this to 3.5 mV max at 25°C due to tighter factory trimming. Both share identical pinout, package, and AC specifications - the 'A' grade is selected when sub-4 mV initial offset is required for high-accuracy DC-coupled systems.

Can unused channels in TL054CNSR be left unconnected?

No - unused op-amp channels in TL054CNSR must be configured as unity-gain buffers with inputs tied to a valid common-mode voltage (e.g., mid-supply via resistive divider) to prevent oscillation or excessive current draw. Leaving inputs floating violates recommended practice per Section 5.1.2 of the datasheet and risks instability.
