Product details
Overview
TL054CDBRE4 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 instrumentation, sensor interfaces, and audio preamplification circuits.
For engineers reviewing the TL054CDBRE4 datasheet, TL054CDBRE4 pinout, TL054CDBRE4 application, or TL054CDBRE4 equivalent, key selection criteria include its ±5V to ±15V dual-supply operation, low 5.5 mV max input offset voltage (25°C), 10.8 nV/√Hz input voltage noise at 1 kHz, and compatibility with high-impedance sources up to 100 MΩ.
Technical Context
The TL054CDBRE4 implements a JFET-input front-end architecture enabling ultra-low input bias current (≤100 pA at 25°C) and high DC precision without sacrificing AC performance. Its trimmed offset voltage and improved process yield 3.5× lower typical VIO than TL084 and 2× better CMRR (92 dB typ) than TL074 under ±15 V conditions.
It operates across 0°C to 70°C ambient temperature with guaranteed performance at both ±5 V and ±15 V supplies, supports rail-to-rail output swing into 2 kΩ loads (±11.5 V), and maintains stable unity-gain operation with ≥60° phase margin up to 1000 pF capacitive loading when series output resistance is applied.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±5 V to ±15 V - supports dual-supply industrial and test equipment rails without level-shifting circuitry |
| Unity-Gain Bandwidth | 4.5 MHz - enables stable amplification of audio-band and medium-speed control signals |
| Slew Rate | 15.4 V/μs (positive), 13.9 V/μs (negative) - ensures <1% THD at 1 kHz with ±10 V output swing |
| Input Offset Voltage | 5.5 mV max (25°C), 7.7 mV max (full range) - reduces DC error in multi-stage gain blocks and sensor bridges |
| Input Resistance | 1012 Ω - preserves signal integrity from piezoelectric sensors, pH electrodes, and photodiode transimpedance stages |
| Input Voltage Noise | 10.8 nV/√Hz @ 1 kHz - critical for low-level signal amplification where source impedance exceeds 50 kΩ |
| Common-Mode Rejection | 92 dB typ @ 25°C - suppresses interference in differential measurement topologies |
Pinout & Package
TL054CDBRE4 is housed in a 14-pin SSOP (DB) package measuring 6.20 mm × 5.30 mm, with 0.65 mm lead pitch and exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output | Amplifier channel 1 output - drives loads ≥2 kΩ directly; requires series resistor for >100 pF capacitive loads |
| 1IN– | Input | Inverting input, channel 1 - high-impedance node requiring guard ring layout for leakage control |
| 1IN+ | Input | Non-inverting input, channel 1 - referenced to common-mode voltage range of –11 V to +11 V (±15 V supply) |
| VCC+ | Power | Positive supply rail - must be decoupled with 0.1 μF ceramic capacitor near pin |
| 2IN+ | Input | Non-inverting input, channel 2 - independent of channel 1; no internal crosstalk beyond 106 dB attenuation |
| 2IN– | Input | Inverting input, channel 2 - shares same input stage topology and noise characteristics as channel 1 |
| 2OUT | Output | Amplifier channel 2 output - identical electrical specs to 1OUT; usable for dual-channel instrumentation |
| 3OUT | Output | Amplifier channel 3 output - enables three-channel simultaneous signal processing without external multiplexing |
| 3IN– | Input | Inverting input, channel 3 - supports fully differential configurations when paired with 3IN+ |
| 3IN+ | Input | Non-inverting input, channel 3 - matches input offset drift and bias current of other channels |
| VCC– | Power | Negative supply rail - symmetric to VCC+; required for proper common-mode input range operation |
| 4IN+ | Input | Non-inverting input, channel 4 - allows four independent gain stages in single IC footprint |
| 4IN– | Input | Inverting input, channel 4 - enables active filtering or summing networks per channel |
| 4OUT | Output | Amplifier channel 4 output - completes quad-channel functionality; all outputs specified for ±80 mA short-circuit current |

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 18 nV/√Hz input noise, 10 mV max VIO, no on-chip trimming | Lower cost; acceptable where DC accuracy <±5 mV and noise <15 nV/√Hz suffice | Choose TL074CDR only if budget constraints outweigh need for trimmed offset and lower noise |
| TL084CDR | Same pinout but higher 25 nV/√Hz noise, 15 mV max VIO, no trimming, slower 3 MHz GBW | Legacy drop-in replacement where existing layouts cannot accommodate new thermal or noise requirements | Use TL084CDR only for backward-compatible repairs - not for new precision designs |
Compared with TL074CDR and TL084CDR, TL054CDBRE4 delivers 53% lower input noise, 45% tighter offset voltage, and 50% higher slew rate within identical SSOP-14 footprint - making it the optimal upgrade path for performance-critical analog signal chains.

FAQ
What supply voltage ranges does the TL054CDBRE4 support?
The TL054CDBRE4 is fully specified for dual-supply operation from ±5 V to ±15 V. It maintains guaranteed electrical performance across this entire range, including input offset voltage, CMRR, and slew rate. Operation outside these limits risks permanent damage per absolute maximum ratings - do not exceed ±18 V on either rail. For single-supply use, external DC biasing and virtual-ground generation (e.g., TLE2426) are required due to FET-input architecture limitations.
How does the TL054CDBRE4 compare to the TL074 and TL084 in terms of noise performance?
The TL054CDBRE4 achieves 10.8 nV/√Hz input voltage noise at 1 kHz - 40% lower than TL074CDR (18 nV/√Hz) and 57% lower than TL084CDR (25 nV/√Hz). This improvement stems from TI's enhanced FET process and optimized input stage design. At 10 Hz, TL054CDBRE4 specifies 50 nV/√Hz vs 70 nV/√Hz for TL074 - confirming superior low-frequency noise behavior critical for DC-coupled sensor applications.
Can the TL054CDBRE4 drive capacitive loads, and what precautions are needed?
Yes, the TL054CDBRE4 can drive capacitive loads up to 1000 pF when a small series resistance (typically 10–100 Ω) is added between the output and load. Without this resistor, oscillation may occur above ~100 pF due to phase margin degradation. The device maintains ≥60° phase margin with 25 pF load (test condition), but stability must be verified per application using Figure 5-2 test circuit. Avoid direct connection to long cables or unbuffered ADC inputs without isolation.
What is the maximum output current capability of each amplifier in the TL054CDBRE4?
Each amplifier in the TL054CDBRE4 is rated for ±80 mA output current under short-circuit conditions at 25°C. Continuous output current should be limited to ≤±25 mA to maintain thermal stability in the SSOP-14 package (θJA = 96°C/W). Derating is required above 70°C ambient - consult thermal data in Section 4.2. Output current capability is symmetrical for sourcing and sinking, supporting rail-to-rail operation into moderate loads like 2 kΩ or higher.
Is the TL054CDBRE4 pin-compatible with other quad op-amps in SOIC or SSOP packages?
Yes, TL054CDBRE4 uses the industry-standard 14-pin SSOP (DB) footprint and is pin-compatible with TL074CDR, TL084CDR, and TL064CDR in the same package variant. Pin functions match exactly per Table 3-3: all four channels follow identical IN+/IN–/OUT ordering, with shared VCC+ and VCC– rails. However, performance differences (noise, offset, slew rate) require verification in final circuit validation - pin compatibility does not guarantee functional equivalence.
