Product details
Overview
TL054CDE4 from Texas Instruments is a quad FET-input operational amplifier with on-chip offset-voltage trimming, delivering 4.5 MHz unity-gain bandwidth, 17.8 V/μs positive slew rate (±15 V), and 1012 Ω input resistance. It operates from ±5 V to ±15 V supplies and is specified for 0°C to 70°C ambient, targeting precision analog signal conditioning in instrumentation and sensor interfaces.
For engineers reviewing the TL054CDE4 datasheet, TL054CDE4 pinout, TL054CDE4 application, or TL054CDE4 equivalent, key selection criteria include its low 5.5 mV max input offset voltage (25°C, ±5 V), 10.8 nV/√Hz input voltage noise at 1 kHz, and compatibility with high-impedance sources up to 100 kΩ without significant current-noise degradation.
Technical Context
The TL054CDE4 implements a JFET-input differential pair architecture with trimmed DC performance, enabling stable operation in high-gain, low-drift configurations. Its design improves upon TL07x/TL08x families via enhanced process and layout optimization-yielding higher bandwidth and slew rate without increased quiescent current (8.1–11.2 mA total for four amplifiers).
It supports dual-supply operation only; single-supply use requires external DC biasing and virtual-ground generation (e.g., TLE2426). Input common-mode range extends to within 1.5 V of rails at ±5 V, and output swing reaches ±11.5 V into 2 kΩ at ±15 V, preserving dynamic range in precision linear applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±5 V to ±15 V - supports standard dual-rail lab and industrial supply rails without level-shifting circuitry |
| Unity-Gain Bandwidth | 4.5 MHz - enables stable closed-loop gain ≥10 up to ~450 kHz with adequate phase margin |
| Input Offset Voltage | 5.5 mV max (25°C, ±5 V) - ensures ≤5.5 mV DC error in unity-gain buffer or differential stage without external nulling |
| Slew Rate | 17.8 V/μs (positive, ±15 V) - supports full-scale 10 VPP sine output up to ~280 kHz before slew limiting |
| Input Resistance | 1012 Ω - minimizes loading on high-Z sensors (e.g., piezoelectric, pH electrodes, photodiode transimpedance feedback) |
| Input Voltage Noise | 10.8 nV/√Hz @ 1 kHz - lower than TL084 (18 nV/√Hz), critical for low-level AC signal amplification |
| CMRR | 92 dB min (25°C, ±15 V) - rejects common-mode interference in differential measurement front-ends |
Pinout & Package
TL054CDE4 is housed in a 14-pin SOIC (D package) with 4.90 mm × 3.90 mm body size and standard JEDEC MS-012AC footprint. Pin 1 is channel 1 output; pins 4 and 11 are dedicated VCC+ and VCC− power terminals; all four amplifier sections share no internal connection between channels except supply rails.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output channel 1 | Low-impedance buffered output; drives loads ≥2 kΩ without stability compromise |
| 2 | Inverting input, ch. 1 | High-Z node requiring guard ring or low-leakage PCB layout for sub-pA bias integrity |
| 3 | Non-inverting input, ch. 1 | Accepts high-impedance source directly; common-mode range limited by supply rails |
| 4 | Power supply positive | Must be decoupled locally with 0.1 μF ceramic; shared across all four amplifiers |
| 5 | Non-inverting input, ch. 2 | Independent input; no crosstalk path to ch. 1 beyond supply coupling (106 dB attenuation) |
| 6 | Inverting input, ch. 2 | Matches ch. 1 input characteristics; usable in matched dual-channel instrumentation topologies |
| 7 | Output channel 2 | Electrically isolated from ch. 1 output; supports independent feedback networks |
| 8 | Output channel 3 | Enables three-channel simultaneous processing (e.g., RGB signal conditioning, multi-axis sensor) |
| 9 | Inverting input, ch. 3 | Validated for same input bias current (10 pA typ) and offset specs as ch. 1/2 |
| 10 | Non-inverting input, ch. 3 | Supports identical common-mode voltage range and noise performance as other channels |
| 11 | Power supply negative | Return path for all four amplifiers; must be low-impedance and star-connected for noise control |
| 12 | Non-inverting input, ch. 4 | Final channel input; fully characterized per spec table - no derating required |
| 13 | Inverting input, ch. 4 | Validated for same input capacitance (10 pF) and CMRR as ch. 1–3 |
| 14 | Output channel 4 | Delivers same slew rate and output swing capability as ch. 1–3 under identical load conditions |
Key Features
| Feature | Design Value |
|---|---|

| Enhanced slew rate & bandwidth | 17.8 V/μs / 4.5 MHz outperforms TL084 (13 V/μs / 1.3 MHz) while maintaining same 1.4 mA/amplifier quiescent current |
| Low 1/f noise corner | 50 nV/√Hz @ 10 Hz - supports precision DC-coupled amplification of slow-varying signals (e.g., thermocouple, strain gauge) |
| Quad-channel integration | Four independent amplifiers in one SOIC-14 reduce board area vs. discrete TL051C solutions and minimize inter-channel skew |

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 18 nV/√Hz input noise, 1.3 MHz bandwidth, 13 V/μs slew rate; no on-chip offset trimming (10 mV max) | Less suitable for sub-mV DC signal chains or >100 kHz AC-coupled paths | Lower-cost option where 5.5 mV offset and 4.5 MHz BW are non-critical |
| OPA4134UA | Lower 8 nV/√Hz noise, 4 MHz BW, rail-to-rail output; ±18 V abs max rating vs. TL054CDE4's ±18 V | Better for low-voltage single-supply designs; not pin-compatible due to different pinout and supply pin locations | Preferred when noise floor or output swing near rails is prioritized over legacy TL07x/TL08x drop-in replacement |
Compared with TL084CDR, TL054CDE4 delivers 40% lower input offset and 3.5× higher bandwidth at identical supply current; versus OPA4134UA, it offers guaranteed pin compatibility with TL074/TL084 layouts but lacks rail-to-rail output and has higher noise.

FAQ
What is the maximum operating temperature range for the TL054CDE4?
The TL054CDE4 is rated for an operating free-air temperature range of 0°C to 70°C (C-suffix grade). At 25°C, its input offset voltage is guaranteed ≤5.5 mV under ±5 V supply; over the full 0°C–70°C range, max offset rises to 7.7 mV. Thermal derating is not required within this range, and the device meets all electrical specifications without additional cooling.
Does the TL054CDE4 support single-supply operation?
No, the TL054CDE4 is designed exclusively for dual-supply operation (±5 V to ±15 V). Its input common-mode range and output swing are specified relative to symmetric rails. Single-supply use requires external DC biasing of inputs and a mid-supply virtual ground (e.g., using TI's TLE2426), plus careful attention to input voltage limits to avoid phase reversal or latch-up.
How does the TL054CDE4 compare to the TL084 in terms of noise performance?
The TL054CDE4 specifies 10.8 nV/√Hz input voltage noise at 1 kHz, significantly lower than the TL084's 18 nV/√Hz. At 10 Hz, TL054CDE4 is 50 nV/√Hz vs. TL084's 70 nV/√Hz. This 30–40% noise reduction directly improves SNR in low-frequency sensor amplification, especially with source impedances >50 kΩ where current noise becomes negligible.
Is the TL054CDE4 pin-compatible with the TL084CDR?
Yes, the TL054CDE4 uses the same SOIC-14 (D) package and identical pin configuration as the TL084CDR and TL074CDR. Pin 1 is output of amplifier A, pins 2/3 are its inverting/non-inverting inputs, pin 4 is VCC+, and so on - enabling direct PCB-level replacement without layout changes or schematic updates.
What is the typical supply current consumption of the TL054CDE4?
The TL054CDE4 draws 8.1–11.2 mA total supply current across all four amplifiers at 25°C with no load, depending on supply voltage (±5 V yields lower current than ±15 V). This equates to ~2.0–2.8 mA per amplifier - identical to TL084, confirming that the enhanced bandwidth and slew rate are achieved without increased power penalty.
