Product details
Overview
TL054AING4 from Texas Instruments is a quad FET-input operational amplifier with on-chip offset-voltage trimming, delivering 3.5 mV max input offset voltage (25°C), 17.8 V/μs slew rate, and 4.5 MHz unity-gain bandwidth at ±15 V supply. It operates across –40°C to 85°C and targets precision analog signal conditioning in instrumentation, sensor interfaces, and audio preamplification.
For engineers reviewing the TL054AING4 datasheet, TL054AING4 pinout, TL054AING4 application, or TL054AING4 equivalent, key selection criteria include its FET-input high-impedance (10¹² Ω), low 10.8 nV/√Hz input voltage noise at 1 kHz, rail-to-rail output swing capability under 2 kΩ load, and compatibility with existing TL07x/TL08x PCB layouts.
Technical Context
The TL054AING4 employs enhanced JFET-input stages with laser-trimmed offset circuitry to achieve improved DC accuracy over legacy TL084 while retaining pin compatibility. Its internal architecture supports stable operation with capacitive loads up to 1000 pF when series output resistance is applied.
Designed for dual-supply operation (±5 V to ±15 V), it features common-mode input range extending to within 2.3 V of rails and output swing to within 1.5 V of supplies-requiring careful biasing in single-supply configurations. The device exhibits 92 dB typical CMRR and 99 dB typical PSRR at 25°C, enabling robust performance in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | Max 3.5 mV at 25°C - enables <1 LSB error in 12-bit ADC front-ends without external nulling |
| Slew Rate | 17.8 V/μs - supports clean 10 Vpp signals up to ~280 kHz in unity-gain buffer configuration |
| Unity-Gain Bandwidth | 4.5 MHz - sufficient for anti-aliasing filters and active low-pass stages up to 200 kHz |
| Input Resistance | 10¹² Ω - preserves signal integrity from high-impedance sources like piezoelectric sensors |
| Supply Current (quad) | 12.8 mA max at ±15 V - allows four independent channels with <3.2 mA/channel average power draw |
| CMRR | 92 dB typical - rejects >10⁴× common-mode interference in differential sensor amplifiers |
| Input Voltage Noise | 10.8 nV/√Hz at 1 kHz - lower than TL084 (18 nV/√Hz), critical for low-level audio and medical signal gain |
Pinout & Package
TL054AING4 is supplied in a 14-pin SOIC (D) package measuring 4.90 mm × 3.90 mm, with standard 1.27 mm pitch and gull-wing leads suitable for automated SMT assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output | Amplifier A output - drives external load or feedback network; requires decoupling near VCC+ and VCC– |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad FET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL084CDR | Higher 10 mV max VIO, 13 V/μs slew rate, 3.8 MHz GBW, no on-chip trimming | Acceptable where calibration is performed at system level; less suitable for uncalibrated portable instruments | Lower cost option when offset drift and noise specs are non-critical |
| TLE2084CDR | 20 V/μs slew rate, 9 MHz GBW, 1.9 mV max VIO, higher 3.6 mA/channel supply current | Better for wideband active filters and fast-settling data acquisition; consumes ~2× more power | Preferred when bandwidth and speed outweigh quiescent power constraints |
Compared with TL084CDR, TL054AING4 offers tighter DC accuracy and lower noise at similar power; versus TLE2084CDR, it trades bandwidth and slew rate for lower supply current and cost-making it optimal for battery-powered precision analog front-ends.

FAQ
What is the maximum operating temperature range for TL054AING4?
The TL054AING4 is specified for operation from –40°C to +85°C ambient temperature. This extended industrial temperature range ensures reliable performance in factory automation, outdoor instrumentation, and automotive under-hood sensing applications where thermal stress is present. The device's offset voltage drift remains controlled at 23 μV/°C across this range, supporting stable long-term measurements without recalibration.
Can TL054AING4 operate from a single 5-V supply?
TL054AING4 is designed for dual-supply operation and is not characterized for true single-supply use. While it may function with a 5-V rail-to-rail configuration (e.g., 0 V and 5 V), its common-mode input range is limited to –1 V to +4 V at ±5 V supplies-and undefined below –1 V. For robust single-supply designs, TI recommends LinCMOS amplifiers (e.g., TLC27L4) with rail-to-rail input/output and guaranteed operation down to 0 V.
How does TL054AING4 compare to TL084 in terms of noise performance?
TL054AING4 delivers 10.8 nV/√Hz input voltage noise at 1 kHz-significantly lower than TL084's 18 nV/√Hz. This 7.2 nV/√Hz improvement directly enhances signal-to-noise ratio in low-amplitude applications such as electrophysiology, piezoelectric vibration sensing, and microphone preamplification. The reduced noise floor stems from TI's enhanced FET process and optimized input stage design.
Is TL054AING4 pin-compatible with TL074 and TL084?
Yes, TL054AING4 uses the same 14-pin SOIC (D) package and identical pinout as TL074 and TL084. Pin functions-including VCC+, VCC–, all four IN+/IN– pairs, and corresponding OUT pins-are fully aligned. This allows direct PCB-level replacement without layout modification, making TL054AING4 a seamless upgrade path for improving DC accuracy, noise, and slew rate in legacy designs.
What is the recommended output load capacitance limit for TL054AING4?
TL054AING4 is characterized with 10 pF load capacitance, but can reliably drive up to 1000 pF when a small series resistor (typically 10–100 Ω) is added between the output pin and the capacitive load. Exceeding this without isolation risks instability, ringing, or oscillation due to phase margin degradation. Applications requiring heavy capacitive loading-such as driving long cables or LCD bias networks-must include this series resistor per channel.
