Product details
Overview
TL054CNG4 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 TL054CNG4 datasheet, TL054CNG4 pinout, TL054CNG4 application, or TL054CNG4 equivalent, key selection criteria include its low 5.5 mV max input offset voltage (25°C, ±5 V), 106 dB crosstalk attenuation, 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 TL054CNG4 implements a JFET-input differential pair architecture optimized for enhanced DC accuracy and AC performance over legacy TL07x/TL08x families. Its trimmed offset voltage and improved process yield tighter initial VIO (≤5.5 mV) and lower drift (25 μV/°C) while maintaining FET-level input impedance and bipolar-like output drive capability.
Designed for dual-supply operation, it supports rail-to-rail input common-mode range (–11 V to +11 V at ±15 V) and delivers ±11.5 V output swing into 2 kΩ load. The device exhibits stable 60° phase margin at unity gain with 25 pF capacitive load and requires no external compensation for standard gain configurations.
Key Specifications

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 |
|---|---|---|---|
| TL084CN | No on-chip offset trimming; 15 mV max VIO (25°C); higher 18 nV/√Hz noise at 1 kHz | Acceptable where calibration is performed post-assembly; unsuitable for zero-drift-critical front-ends | Select TL084CN only if cost sensitivity outweighs DC accuracy and noise requirements |
| TL074CN | Lower 15 V/μs slew rate; identical 4.5 MHz bandwidth but 75 dB min CMRR vs TL054C's 75 dB min | Valid for audio line-level buffering but marginal for fast-settling data acquisition | Choose TL074CN when ultra-low noise (7 nV/√Hz) is prioritized over speed and DC precision |
Compared with TL084CN and TL074CN, TL054CNG4 provides superior DC accuracy (5.5 mV vs 15 mV VIO), lower noise (10.8 vs 18 nV/√Hz), and faster slew rate (17.8 vs 13 V/μs), making it optimal for precision multi-channel signal chains where calibration overhead must be minimized.

FAQ
What is the maximum operating supply voltage for TL054CNG4?
The TL054CNG4 has absolute maximum supply ratings of ±18 V, but it is fully specified for reliable operation from ±5 V to ±15 V. Operation at ±18 V is not characterized and may result in degraded parameters or reduced reliability. For designs requiring wider supply range, consider TI's TLC27L4 or OPA4340 families.
Does TL054CNG4 support single-supply operation?
The TL054CNG4 is designed for dual-supply operation and does not feature rail-to-rail input or output. When used with single supplies, external DC biasing (e.g., TLE2426 virtual ground) is required to establish proper common-mode voltage, and output swing remains limited to ~3 V below VCC and ~2.5 V above ground at ±5 V equivalent.
How does TL054CNG4 differ from TL054ACNG4?
The TL054ACNG4 is the precision-grade variant with tighter specifications: max 3.5 mV input offset voltage (vs 5.5 mV for TL054CNG4) and lower 23 μV/°C temperature coefficient. Both share identical pinout, package, and AC performance. TL054CNG4 is intended for cost-sensitive applications where ±5.5 mV offset is acceptable.
Can unused amplifiers in TL054CNG4 be left floating?
No - unused amplifiers in TL054CNG4 must be configured as unity-gain buffers (output tied to inverting input, non-inverting input biased within common-mode range) to prevent oscillation or excessive current draw. Leaving inputs or outputs unconnected risks instability due to internal parasitic coupling and undefined bias conditions.
What is the thermal resistance (θJA) of TL054CNG4 in PDIP package?
The TL054CNG4 in N-package (PDIP-14) has a junction-to-ambient thermal resistance (θJA) of 80°C/W under standard JEDEC 2-layer board conditions. This value assumes 1 in² copper pad per power pin and defines maximum allowable power dissipation (PD = (TJMAX – TA)/θJA) for safe operation at 70°C ambient.
