Product details
Overview
TL054CDBRG4 from Texas Instruments is a quad FET-input operational amplifier with on-chip offset-voltage trimming, 4.5 MHz unity-gain bandwidth, 15.4 V/μs positive slew rate, and 1012 Ω input resistance-designed for precision analog signal conditioning in audio preamplifiers, sensor interfaces, and instrumentation circuits.
For engineers reviewing the TL054CDBRG4 datasheet, TL054CDBRG4 pinout, TL054CDBRG4 application, or TL054CDBRG4 equivalent, key selection criteria include its ±5V to ±15V dual-supply operation, 5.5 mV max input offset voltage (25°C), 106 dB crosstalk attenuation, and SOIC-14 package compatibility with legacy TL074/TL084 layouts.
Technical Context
The TL054CDBRG4 implements a JFET-input differential pair architecture with trimmed DC performance, delivering improved AC response over TL084 while retaining low noise (10.8 nV/√Hz at 1 kHz) and high CMRR (92 dB typ). Its phase margin remains stable at 60° across temperature and load conditions.
It operates within 0°C to 70°C ambient range under ±5V or ±15V supplies, supports rail-to-rail output swing limited by supply headroom (e.g., ±13.9 V at ±15 V/10 kΩ), and requires dual-supply biasing-no single-supply virtual-ground circuitry is integrated.
Key Specifications

|---|---|
| Unity-gain bandwidth | 4.5 MHz - enables stable closed-loop gain ≥1 up to audio and low-speed data acquisition frequencies |
| Input offset voltage (max) | 5.5 mV at 25°C - ensures ≤5.5 mV DC error in precision DC-coupled amplification stages |
| Slew rate (positive) | 15.4 V/μs - supports ≤1.5 Vpp full-power bandwidth of ~1.6 MHz at unity gain |
| Input resistance | 1012 Ω - minimizes loading on high-impedance sources like piezoelectric sensors or pH electrodes |
| Crosstalk attenuation | 106 dB - prevents inter-channel coupling in multi-channel instrumentation or audio mixing applications |
| Common-mode rejection ratio | 92 dB (typ) - rejects shared noise in differential sensing configurations with mismatched source impedances |
| Supply current (quiescent) | 11.2 mA (max) - allows four independent amplifiers per IC with moderate power budget allocation |
Pinout & Package
TL054CDBRG4 is housed in a 14-pin SOIC (D) package measuring 4.90 mm × 3.90 mm, with standard JEDEC MS-012AC footprint and 1.27 mm pitch. Pin 1 is marked with a beveled corner or dot; device orientation follows TI's top-view convention.

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 offset (10 mV max), lower slew rate (13 V/μs), no on-chip trimming | Acceptable where DC precision is secondary to cost; not suitable for sub-mV offset-critical designs | Select TL074CDR only if legacy design reuse and BOM cost reduction outweigh need for improved DC stability |
| TL084CDR | Worse noise (18 nV/√Hz), higher input bias current (2 nA), no trimming | Used in general-purpose analog circuits where speed > precision; lacks TL054CDBRG4's low-noise advantage | Choose TL084CDR when bandwidth requirements exceed 3 MHz but noise floor is not critical |
Compared with TL074CDR and TL084CDR, TL054CDBRG4 delivers tighter DC specifications, superior noise performance, and guaranteed pin compatibility-making it the optimal upgrade for existing TL07x/TL08x-based systems requiring measurable precision improvement without layout changes.

FAQ
What is the maximum operating temperature range for TL054CDBRG4?
The TL054CDBRG4 is rated for operation from 0°C to 70°C ambient temperature under recommended supply conditions (±5 V or ±15 V). It is not qualified for extended industrial or automotive temperature ranges; for –40°C to 85°C operation, the TL054IDR variant should be selected instead. The TL054CDBRG4's electrical characteristics-including input offset voltage, CMRR, and slew rate-are fully specified across this 0°C to 70°C range per the SLOS178B datasheet revision.
Does TL054CDBRG4 support single-supply operation?
No, TL054CDBRG4 is designed exclusively for dual-supply operation (±5 V to ±15 V) and does not support true single-supply use. Its common-mode input voltage range and output swing are defined relative to symmetric rails, and internal circuitry requires both positive and negative supplies to function correctly. Attempting single-supply operation without external biasing (e.g., virtual ground generation using TLE2426) will result in clipping, distortion, or failure to amplify near-rail signals.
What is the input offset voltage specification for TL054CDBRG4?
The TL054CDBRG4 has a maximum input offset voltage of 5.5 mV at 25°C and 7.7 mV across the full 0°C to 70°C operating range, as specified in Section 4.4 of the SLOS178B datasheet. This value reflects on-chip trimming that improves upon untrimmed predecessors like TL084. The typical offset is 4.0 mV at 25°C, and long-term drift is specified at 0.04 μV/month-enabling stable DC performance in calibration-sensitive applications.
Is TL054CDBRG4 pin-compatible with TL074 and TL084?
Yes, TL054CDBRG4 is fully pin-compatible with TL074CDR and TL084CDR in the SOIC-14 (D) package. Pin functions-including VCC+, VCC–, all four IN+/IN– pairs, and corresponding OUT pins-are identical per Figure 3-3 and Table 3-3 of the datasheet. No PCB layout changes are needed when upgrading from TL074 or TL084 to TL054CDBRG4, making it a drop-in performance enhancement for existing designs.
What is the unity-gain bandwidth and phase margin of TL054CDBRG4?
The TL054CDBRG4 has a unity-gain bandwidth of 4.5 MHz and a phase margin of 60° at unity gain, measured under standard test conditions (VCC± = ±15 V, RL = 2 kΩ, CL = 25 pF). These values are stable across temperature and supply voltage variations, ensuring predictable stability in voltage-follower and low-gain configurations without requiring external compensation networks.
