Product details
Overview
TL054CDBR 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 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 TL054CDBR datasheet, TL054CDBR pinout, TL054CDBR application, or TL054CDBR equivalent, this page provides verified electrical specifications, SOIC-14 package details, confirmed pin functions, and validated alternative options for precision FET op-amp selection in industrial instrumentation and data acquisition circuits.
Technical Context
The TL054CDBR implements a JFET-input differential pair architecture with on-chip offset-voltage trimming, delivering improved DC accuracy over TL07x/TL08x families without sacrificing AC performance. Its design maintains rail-to-rail output swing capability within ±11 V (at ±15 V supply) and supports stable operation with capacitive loads up to 1000 pF when series output resistance is applied.
It operates across 0°C to 70°C (C-suffix), is fully specified at ±5 V and ±15 V supplies, and requires dual-supply biasing - limiting direct use in single-supply systems unless external virtual-ground circuitry (e.g., TLE2426) is employed. Common-mode input range spans –11 V to +11 V under ±15 V conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad FET op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL074CDR | Higher input voltage noise (18 nV/√Hz), lower slew rate (13 V/μs), no on-chip offset trimming | Acceptable where cost is critical and DC accuracy less demanding than TL054CDBR | Use TL074CDR only if system tolerates higher VIO (max 10 mV) and slower transient response |
| TL084CDR | Higher input bias current (up to 4 nA), untrimmed offset (max 15 mV), same 4.5 MHz bandwidth | Suitable for AC-coupled or non-precision DC applications where input impedance >10⁹ Ω suffices | Select TL084CDR when ultra-low IB is unnecessary and budget constraints outweigh precision requirements |
Compared with TL074CDR and TL084CDR, TL054CDBR provides superior DC accuracy (5.5 mV vs 10/15 mV VIO), lower noise (10.8 vs 18 nV/√Hz), and faster slew rate (17.8 vs 13/13 V/μs), making it optimal for precision multi-channel analog acquisition where long-term stability and low-frequency fidelity are essential.

FAQ
What is the maximum supply voltage rating for TL054CDBR?
The TL054CDBR has an absolute maximum supply voltage rating of ±18 V. It is fully specified for reliable operation at ±5 V and ±15 V dual supplies. Operation beyond ±15 V is not recommended for sustained use, as parameters such as input offset voltage and CMRR are characterized only up to ±15 V per the datasheet's Recommended Operating Conditions table.
Can TL054CDBR operate from a single supply?
No - TL054CDBR is designed exclusively for dual-supply operation. Its common-mode input voltage range and output swing are defined relative to symmetric positive and negative rails. Single-supply use requires external biasing (e.g., TLE2426 virtual ground) and careful DC level shifting; TI explicitly recommends LinCMOS TLC-series op-amps for native single-supply applications.
What is the input offset voltage specification for TL054CDBR at full temperature range?
For the TL054CDBR (C-suffix, 0°C to 70°C), the maximum input offset voltage is 7.7 mV across the full operating temperature range. At 25°C, the typical value is 4.0 mV, with a maximum of 5.5 mV. This is confirmed in Section 4.4 of the SLOS178B datasheet under "TL05xC and TL05xAC Electrical Characteristics."
Is TL054CDBR pin-compatible with TL084CDR?
Yes - TL054CDBR is pin-compatible with TL084CDR and TL074CDR in the SOIC-14 (D) package. All three share identical pinout (Table 3-3), allowing drop-in replacement in existing layouts. However, differences in input bias current, noise, and offset require verification of system-level performance after substitution.
What is the thermal resistance (θJA) of TL054CDBR in SOIC-14 package?
The junction-to-ambient thermal resistance (θJA) for TL054CDBR in the SOIC-14 (D) package is 86 °C/W, as specified in Section 4.2 "Thermal Information" of the SLOS178B datasheet. This value assumes standard JEDEC 2S2P board conditions and guides thermal design for continuous operation at rated supply currents.
