Product details
Overview
TL054CD 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, and 1012 Ω input resistance at ±15 V supply. It operates across 0°C to 70°C and supports precision signal conditioning in audio preamps, sensor interfaces, and instrumentation circuits.
For engineers reviewing the TL054CD datasheet, TL054CD pinout, TL054CD application, or TL054CD equivalent, key selection criteria include its low 3.5 mV max input offset voltage (C-grade, full temperature range), 106 dB crosstalk attenuation between channels, and compatibility with ±5 V to ±15 V dual supplies - critical for high-impedance source interfacing and low-noise analog front-ends.
Technical Context
The TL054CD uses JFET-input stages to achieve ultra-high input impedance and low input bias current (≤200 pA at 25°C), enabling accurate amplification of microvolt-level signals from piezoelectric sensors or photodiode transimpedance nodes. Its internal offset trimming eliminates external nulling circuitry in DC-coupled applications.
Designed as a direct upgrade to TL074 and TL084, the TL054CD maintains identical SOIC-14 pinout while improving AC performance: 15.4–17.8 V/μs slew rate and 4.5 MHz bandwidth exceed TL084's 13 V/μs and 3 MHz, without increasing quiescent current (8.1–11.2 mA total for four amplifiers).
Key Specifications

|---|---|
| Supply Voltage Range | ±5 V to ±15 V - supports both low-voltage portable systems and industrial ±15 V rails |
| Input Offset Voltage (max) | 3.5 mV over 0°C–70°C - enables <1 LSB error in 12-bit ADC front-ends with gain ≤100 |
| Unity-Gain Bandwidth | 4.5 MHz - sufficient for audio band (20 Hz–20 kHz) with >100 dB open-loop gain margin |
| Slew Rate (positive) | 17.8 V/μs at ±15 V - ensures distortion-free 10 VPP @ 100 kHz sine wave output |

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 |
|---|---|---|---|
| TL074CD | Higher 25 nV/√Hz input noise at 1 kHz; 3 MHz bandwidth; no on-chip offset trimming (max 10 mV offset) | Acceptable for non-critical audio or general-purpose gain stages where cost is prioritized over DC precision | Choose TL074CD only if system-level offset calibration is implemented externally and noise floor >15 nV/√Hz is tolerable |
| TL084CD | Lower 13 V/μs slew rate; higher 18 nV/√Hz noise; same pinout but untrimmed offset (max 15 mV) | Suitable for slower control loops or AC-coupled signal paths where DC accuracy is not required | Select TL084CD when bandwidth demand is <2 MHz and power efficiency (7.5 mA total) outweighs precision needs |
Compared with TL074CD and TL084CD, the TL054CD provides superior DC accuracy (3.5 mV vs 10–15 mV offset), lower noise (10.8 vs 18–25 nV/√Hz), and faster slew rate (17.8 vs 13–20 V/μs), making it the optimal choice for precision multi-channel analog systems requiring minimal post-fabrication calibration.

FAQ
What is the maximum operating temperature range for the TL054CD?
The TL054CD is specified for operation from 0°C to 70°C ambient temperature. This commercial-grade temperature range is validated per JEDEC JESD22-A104, with all electrical parameters-including input offset voltage, slew rate, and CMRR-guaranteed across this interval. The TL054CD is not rated for extended industrial (–40°C to 85°C) operation; for that range, the TL054ID variant should be selected.
Can the TL054CD operate from a single 5-V supply?
No, the TL054CD 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, and it lacks rail-to-rail input/output capability. Attempting single-supply use without DC biasing violates the absolute maximum rating for input voltage (±15 V) and risks latch-up or parametric failure. For single-supply designs, TI recommends the TLC27L4 or TLV2464 families.
How does the TL054CD's crosstalk attenuation affect multi-channel PCB layout?
The TL054CD's 106 dB crosstalk attenuation between channels means that a 1 V signal on channel A induces less than 0.5 µV on channel B at the output-well below typical 16-bit ADC quantization noise. This allows tight channel spacing on PCBs without guard traces, though best practice still recommends separating analog input routing and using local 0.1 µF VCC+/VCC– decoupling per amplifier pair to maintain PSRR above 75 dB.
Is the TL054CD pin-compatible with the TL084CD?
Yes, the TL054CD is fully pin-compatible with the TL084CD and TL074CD in SOIC-14 (D) packaging. Pin 1 (1OUT) through pin 14 (4OUT) match function-for-function, including identical power pin locations (pin 4 = VCC+, pin 11 = VCC–). This enables drop-in replacement in existing TL084CD layouts to immediately improve offset, noise, and slew rate without PCB revision.
What is the recommended minimum load resistance for stable operation of the TL054CD?
The TL054CD is characterized with 2 kΩ and 10 kΩ loads, and remains stable down to 2 kΩ resistive loading with ≤100 pF capacitive load. For loads <2 kΩ or capacitive loads >100 pF, TI recommends adding a 10–100 Ω series resistor between the output and load to isolate the amplifier from reactive impedance, preventing peaking or oscillation as confirmed in Figure 5-2 of the SLOS178B datasheet.
