For engineers reviewing the TL054IDRG4 datasheet, TL054IDRG4 pinout, TL054IDRG4 application, or TL054IDRG4 equivalent, this page delivers verified specifications, SOIC-14 package details, real-world application context, and validated alternative options - all grounded in TI's SLOS178B production data sheet (Jan 2026 revision).
Technical Context
The TL054IDRG4 implements a high-impedance JFET differential input stage paired with a Class AB output stage, enabling rail-to-rail compatible output swing (±12 V at ±15 V supply) without sacrificing drive capability. Its trimmed input offset voltage (max 6.2 mV over full temperature range) and low 10.8 nV/√Hz input noise at 1 kHz support stable DC-coupled amplification of microvolt-level signals.
It operates across ±5 V to ±15 V dual supplies, with common-mode input range extending to within 2.3 V of either rail. The device features 106 dB crosstalk attenuation between channels and maintains 60° phase margin into 2 kΩ || 25 pF loads - confirming stability in multi-channel feedback configurations without external compensation.

Applications
| Instrumentation Amplifier Front-End | Active Filter Bank |
|---|---|
Use Scenario: Amplifying low-level bridge sensor outputs (e.g., load cells, strain gauges) with high common-mode rejection and minimal offset drift. IC Role / Device Role / Timing Role: TL054IDRG4 serves as the three-op-amp core of a precision instrumentation amplifier, with two channels forming the input gain stage and the third providing offset nulling. Use Value: On-chip trimming holds total system offset error below ±150 μV over temperature - enabling 16-bit effective resolution in 24-bit ADC systems. | Use Scenario: Implementing cascaded 2nd-order low-pass, high-pass, and band-pass filters for audio spectrum analysis or vibration monitoring. IC Role / Device Role / Timing Role: TL054IDRG4 provides four independent, matched gain blocks for Sallen-Key or state-variable filter topologies requiring tight component matching. Use Value: Channel-to-channel gain matching <0.1% and phase tracking <0.5° ensure consistent filter response across frequency bands without calibration. |
| Multi-Channel Sensor Signal Conditioning | Programmable Gain Instrumentation Amplifier |
Use Scenario: Simultaneous acquisition from four independent sensors (e.g., temperature, pressure, humidity, gas concentration) in environmental monitoring nodes. IC Role / Device Role / Timing Role: TL054IDRG4 conditions each sensor's analog output with dedicated amplification, filtering, and level-shifting before multiplexing to an ADC. Use Value: 106 dB inter-channel crosstalk prevents cross-talk-induced measurement errors in mixed-signal environments with >60 dB dynamic range. | Use Scenario: Building a digitally controlled gain stage where gain is adjusted via DAC-driven voltage-controlled resistors or analog switches. IC Role / Device Role / Timing Role: TL054IDRG4 acts as the main amplifier and nulling amplifier in a three-op-amp PGA, with fourth channel buffering reference voltages. Use Value: Input bias current <4 nA at 85°C avoids gain error drift when using MΩ-range programmable resistors, maintaining ±0.02% gain accuracy. |
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 |
|---|---|---|---|
| TL084CDR | Higher input offset (18 mV max), lower slew rate (13 V/μs), no on-chip trimming | Acceptable for non-critical AC-coupled audio preamps but unsuitable for precision DC-coupled sensor front-ends | Select TL084CDR only when cost is primary constraint and offset drift <±500 μV is tolerable |
| OPA4134UA | Lower noise (8 nV/√Hz), higher CMRR (114 dB), wider supply range (±4 V to ±18 V), but higher quiescent current (4 mA per amp) | Better for ultra-low-noise audio or medical EEG front-ends; less suitable for battery-powered systems with tight power budgets | Choose OPA4134UA when noise floor <10 nV/√Hz and CMRR >110 dB are required, and 16 mA total supply current is acceptable |
Compared with TL084CDR, TL054IDRG4 delivers 3× lower offset drift and 37% faster slew rate at identical price; versus OPA4134UA, it consumes 60% less power but trades 2 nV/√Hz noise density for extended operating temperature range (–40°C to +85°C vs –40°C to +70°C).

FAQ
What is the maximum operating temperature range for TL054IDRG4?
The TL054IDRG4 is specified for operation from –40°C to +85°C (I-grade), with all electrical characteristics guaranteed across this full industrial temperature range. At +85°C, key parameters include max 6.2 mV input offset voltage, min 75 dB CMRR, and 17.8 V/μs slew rate - making TL054IDRG4 suitable for under-hood automotive sensors and factory-floor PLC modules where ambient heat exceeds 70°C.
Can TL054IDRG4 operate from a single 5-V supply?
TL054IDRG4 is designed for dual-supply operation (±5 V to ±15 V) and does not support true single-supply use. When powered from 5 V (0 V to 5 V), its common-mode input range is limited to –1 V to +4 V and output swing to +2.5 V to +3.8 V (RL = 2 kΩ), requiring external level-shifting or a virtual-ground generator like TI's TLE2426. For native single-supply designs, consider TI's TLC2274 or MCP6004 instead of TL054IDRG4.
How does TL054IDRG4 compare to TL074 in noise performance?
TL054IDRG4 specifies 10.8 nV/√Hz input voltage noise at 1 kHz - identical to TL074 - but improves low-frequency noise with 50 nV/√Hz at 10 Hz (vs TL074's 70 nV/√Hz). This 29% reduction in 10 Hz noise makes TL054IDRG4 better suited for DC-coupled applications like thermopile amplification or ECG front-ends where 1/f noise dominates. Both share the same JFET input architecture, but TL054IDRG4's on-chip trimming does not degrade noise.
Is TL054IDRG4 pin-compatible with TL084?
Yes, TL054IDRG4 is fully pin-compatible with TL084 in SOIC-14 (D) packages - sharing identical pinout, footprint, and supply connections. This allows direct drop-in replacement in existing TL084 designs to immediately improve offset voltage (6.2 mV vs 18 mV), slew rate (17.8 V/μs vs 13 V/μs), and noise (50 nV/√Hz at 10 Hz vs 80 nV/√Hz), without PCB layout changes. No external component adjustments are needed for basic functionality.
What is the recommended decoupling for TL054IDRG4?
TI recommends placing a 0.1 μF X7R ceramic capacitor between VCC+ and VCC– pins, located ≤2 mm from the TL054IDRG4 package edge. For systems with multiple TL054IDRG4 devices or high-current digital noise sources, add a 4.7 μF tantalum capacitor per supply rail at the board's main power entry point. Avoid electrolytic capacitors near TL054IDRG4 due to their high ESR, which degrades high-frequency PSRR - critical for maintaining 99 dB supply rejection in precision analog stages.
