Product details
Overview
TL054ACD 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), 15.4 V/μs positive slew rate, and 4.5 MHz unity-gain bandwidth at ±15 V supply - designed for precision analog signal conditioning in instrumentation and sensor interfaces.
For engineers reviewing the TL054ACD datasheet, TL054ACD pinout, TL054ACD application, or TL054ACD equivalent, key selection criteria include its FET-input high-impedance interface (10¹² Ω), low 10.8 nV/√Hz input voltage noise at 1 kHz, and guaranteed operation across 0°C to 70°C with ±5 V to ±15 V dual supplies.
Technical Context
The TL054ACD implements a JFET-input front-end architecture with trimmed DC performance, enabling stable high-precision amplification without sacrificing ac response. Its design improves upon TL07x/TL08x families via enhanced process and optimized compensation, achieving higher bandwidth and slew rate at identical quiescent current (8.4 mA typ at ±15 V).
It operates with dual supplies only; common-mode input range spans –12.3 V to +15.1 V at ±15 V, and output swing reaches ±12.7 V into 2 kΩ. Input bias current remains below 30 pA (25°C), supporting high-impedance source interfacing without significant error.
Key Specifications

|---|---|
| Input offset voltage | 3.5 mV max at 25°C - enables <100 µV dc error in gain-of-100 circuits before trimming |
| Slew rate (positive) | 15.4 V/μs typ - supports clean 100 kHz full-scale sine output at 10 Vpp |
| Unity-gain bandwidth | 4.5 MHz - allows stable closed-loop gain ≥10 up to ~450 kHz |
| Input resistance | 10¹² Ω - minimizes loading on piezoelectric sensors and passive RC filters |
| Supply current (quad) | 8.4 mA typ at ±15 V - delivers FET precision without bipolar-level power penalty |
| Input voltage noise | 10.8 nV/√Hz at 1 kHz - outperforms TL084 by >3× in low-frequency sensor amplification |
| Common-mode rejection | 92 dB min - suppresses 50/60 Hz interference in differential measurement setups |

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 |
|---|---|---|---|
| TL084CD | Higher 6 mV max VIO, 13 V/μs slew rate, no on-chip trimming | Acceptable where ±5 mV dc error is tolerable and cost is primary constraint | Use TL084CD only if system-level calibration compensates for higher offset and drift |
| TL074CD | Lower 10.5 nV/√Hz noise at 1 kHz but 10 mV max VIO and no trimming | Suitable for AC-coupled audio paths where dc accuracy is secondary | Select TL074CD when noise dominates performance and dc stability is managed externally |
Compared with TL084CD and TL074CD, TL054ACD provides superior dc precision (3.5 mV vs 6–10 mV VIO) and faster slew rate (15.4 V/μs), making it optimal for dc-coupled sensor interfaces requiring factory-trimmed accuracy without post-assembly calibration.

FAQ
What is the maximum operating temperature range for TL054ACD?
The TL054ACD is characterized for operation from 0°C to 70°C (commercial temperature grade). It meets all electrical specifications across this full range, including input offset voltage ≤5.7 mV, supply current ≤12.8 mA, and output swing ≥±11.5 V into 2 kΩ. Operation outside this range is not guaranteed per datasheet SLOS178B Rev B.
Does TL054ACD support single-supply operation?
No, TL054ACD is designed exclusively for dual-supply operation (±5 V to ±15 V). Its common-mode input range and output swing are specified relative to symmetric rails. Attempting single-supply use without external level-shifting or virtual-ground circuitry (e.g., TI TLE2426) risks saturation, phase reversal, or undefined behavior per Section 2 of the TL054ACD datasheet.
What is the input bias current specification for TL054ACD at 70°C?
At 70°C, TL054ACD exhibits a maximum input bias current of 4 nA (typical 0.2 nA), as confirmed in Table 4.4 of the SLOS178B datasheet. This value reflects worst-case leakage across all four amplifiers under recommended operating conditions (VCC± = ±15 V), ensuring reliable high-impedance node performance in warm industrial environments.
Can TL054ACD drive capacitive loads directly?
TL054ACD can drive ≤100 pF capacitive loads stably without external compensation. For larger loads (e.g., 1000 pF), a series resistor (typically 10–100 Ω) must be added between the output and load to prevent peaking or oscillation, as documented in Section 5.1.2 of the datasheet. Uncompensated loads >500 pF risk instability due to reduced phase margin.
How does TL054ACD differ from TL054CD in precision performance?
TL054ACD features tighter input offset voltage (3.5 mV max vs 4 mV max for TL054CD at 25°C) and lower temperature coefficient (23 μV/°C vs 25 μV/°C), achieved through enhanced on-chip trimming. Both share identical pinout, package, and ac specs, but TL054ACD is selected for applications demanding higher initial dc accuracy and long-term stability without external calibration.
