Product details
Overview
TL054AIN from Texas Instruments is a quad FET-input operational amplifier engineered 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, and 1.5 mV max input offset voltage (TL054AC grade at 25°C), making it suitable for high-impedance sensor interfacing and low-noise audio preamplification.
For engineers reviewing the TL054AIN datasheet, TL054AIN pinout, TL054AIN application, or TL054AIN equivalent, key selection considerations include its on-chip offset-voltage trimming for stable DC performance, compatibility with ±5 V to ±15 V supplies, FET-input architecture enabling >100 dB CMRR at 25°C, and pin-for-pin replacement capability with TL074 and TL084 in SOIC-14 packages.
Technical Context
The TL054AIN uses a JFET-input front-end with on-chip laser-trimmed offset voltage, delivering improved DC accuracy over legacy TL07x/TL08x families without sacrificing AC performance. Its enhanced FET process yields higher slew rate and bandwidth while maintaining quiescent current below 12.8 mA (four amplifiers, ±15 V).
Designed for dual-supply operation, it requires attention to common-mode input voltage limits (–12.3 V to +15.1 V at ±15 V) and output swing constraints-especially when adapted to single-supply use via external biasing or virtual-ground generation using TI's TLE2426.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±5 V to ±15 V - supports industrial and test equipment rails; not rated for single-supply operation without DC biasing. |
| Unity-Gain Bandwidth | 4.5 MHz - enables stable closed-loop gain ≥1 up to audio and low-speed data acquisition frequencies. |
| Slew Rate (+) | 17.8 V/μs at ±15 V - ensures <1% THD for 1 kHz sine waves up to ~10 Vpp output swing into 2 kΩ. |
| Input Offset Voltage | 1.5 mV max (TL054AC, 25°C) - trimmed for precision DC-coupled stages like instrumentation amplifiers. |
| Input Resistance | 10¹² Ω - preserves signal integrity from high-Z sources such as piezoelectric sensors or pH electrodes. |
| CMRR | 92 dB min (25°C, ±15 V) - rejects power supply ripple and shared-noise coupling in multi-channel systems. |
| THD | 0.00021% at 1 kHz - meets fidelity requirements for professional audio line-level signal paths. |
Pinout & Package
TL054AIN is supplied in a 14-pin plastic D (SOIC) package measuring 4.90 mm × 3.90 mm, with standard JEDEC MO-153 footprint and 1.27 mm pitch. Thermal resistance θJA is 86 °C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output | Amplifier channel 1 output; capable of ±11.5 V swing into 2 kΩ load at ±15 V supply. |
| 1IN– | Input | Inverting input for channel 1; high-impedance node requiring guard ring layout for leakage control. |
| 1IN+ | Input | Non-inverting input for channel 1; referenced to common-mode range bounded by supply rails. |
| VCC+ | Power | Positive supply terminal; must be decoupled locally with 0.1 μF ceramic capacitor. |
| 2IN+ | Input | Non-inverting input for channel 2; electrically isolated but shares substrate with other channels. |
| 2IN– | Input | Inverting input for channel 2; crosstalk attenuation to adjacent channels is ≥106 dB. |
| 2OUT | Output | Amplifier channel 2 output; identical AC/DC specs to 1OUT; unused channels should be configured as unity-gain followers. |
| 3OUT | Output | Amplifier channel 3 output; same drive capability and noise floor as other channels. |
| 3IN– | Input | Inverting input for channel 3; layout symmetry recommended to minimize inter-channel mismatch. |
| 3IN+ | Input | Non-inverting input for channel 3; sensitive to PCB contamination due to pA-level input bias current. |
| VCC– | Power | Negative supply terminal; return path for all four amplifiers; star grounding advised. |
| 4IN+ | Input | Non-inverting input for channel 4; full rail-to-rail input common-mode range not supported. |
| 4IN– | Input | Inverting input for channel 4; input capacitance is 10 pF - impacts stability with capacitive loads >100 pF. |
| 4OUT | Output | Amplifier channel 4 output; maximum capacitive load before peaking: ≤500 pF without series resistor. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip offset-voltage trimming | Reduces initial VIO to ≤1.5 mV (TL054AC), enabling DC-coupled gain stages without external nulling circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad FET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL074CDR | Higher input voltage noise (18 nV/√Hz), no on-chip offset trimming (max VIO = 10 mV), 13 V/μs slew rate. | Acceptable where cost sensitivity outweighs noise/DC precision needs; unsuitable for sub-mV DC measurements. | Choose TL074CDR only if legacy design reuse or BOM cost reduction is primary; verify THD and settling time. |
| TL084CDR | Same pinout; higher input bias current (200 pA), higher VIO (6 mV max), 13 V/μs slew rate, 3.8 MHz GBW. | Less suitable for high-Z sensors or low-THD audio; acceptable for general-purpose AC-coupled signal routing. | Prefer TL084CDR only when existing layout tolerates higher noise and offset; avoid in precision DC paths. |
Compared with TL074CDR and TL084CDR, TL054AIN provides superior DC accuracy, lower noise, and faster transient response - justifying its use in instrumentation, audio, and sensor signal chains where performance margins are constrained.

FAQ
What is the maximum operating temperature range for TL054AIN?
The TL054AIN is specified for operation from –40°C to +85°C (I-grade). This extended industrial temperature range ensures reliable performance in harsh environments such as factory automation controllers and outdoor test equipment where ambient temperatures fluctuate widely. The device maintains its 1.5 mV max input offset voltage and 4.5 MHz bandwidth across this full range.
Can TL054AIN operate from a single supply?
TL054AIN is designed for dual-supply operation and is not characterized for true single-supply use. To operate from a single rail, the inputs and output must be biased within the common-mode and output swing limits-for example, using TI's TLE2426 virtual ground generator to establish a mid-supply reference. Without proper DC biasing, the device may saturate or distort.
What is the input capacitance of TL054AIN and how does it affect stability?
TL054AIN has an input capacitance of 10 pF per amplifier. When driving capacitive loads >100 pF, phase margin degrades-potentially causing ringing or oscillation. Stability is restored by adding a small series resistor (e.g., 22–100 Ω) between the output and load. Figure 5-2 in the datasheet shows this compensation technique validated up to 1000 pF.
How does TL054AIN compare to TL074 in terms of noise performance?
TL054AIN achieves 10.8 nV/√Hz input voltage noise at 1 kHz-significantly lower than TL074's 18 nV/√Hz. This 7.2 nV/√Hz improvement directly reduces audible hiss in audio paths and improves signal-to-noise ratio in low-level sensor amplification. The lower noise stems from TI's enhanced FET process and optimized input stage design.
Is TL054AIN pin-compatible with TL084 in SOIC-14 packages?
Yes-TL054AIN uses the same SOIC-14 (D) package and identical pinout as TL084 and TL074. All three share identical power, input, and output terminal assignments per channel. This allows direct PCB-level replacement without layout changes, enabling immediate performance upgrades in existing designs that previously used TL084.
