Product details
Overview
TLE2084ACDW from Texas Instruments is a quad high-speed JFET-input operational amplifier with 10.6 MHz unity-gain bandwidth, 32 V/μs slew rate, ±19 V supply capability, and 4 mV max input offset voltage at 25°C. It serves as a direct upgrade to TL084 in precision analog signal conditioning stages of test equipment and industrial power electronics.
For engineers reviewing the TLE2084ACDW datasheet, TLE2084ACDW pinout, TLE2084ACDW application, or TLE2084ACDW equivalent, this page delivers verified electrical specs, SOIC-16 package layout, real-world use cases in oscilloscopes and energy meters, and two validated alternative op-amps for design flexibility.
Technical Context
The TLE2084ACDW integrates four independent high-voltage JFET-input amplifiers on a single die, each featuring low input bias current (≤175 nA), low noise (7 nV/√Hz at ±15 V), and stable unity-gain operation with 56° phase margin. Its architecture supports rail-to-rail output swing under light loads and maintains DC precision across 0°C to 70°C ambient.
It operates with dual supplies from ±2.25 V to ±19 V, enabling wide dynamic range in AC-coupled instrumentation front-ends and high-voltage sensor interfaces. The device meets Excalibur performance tier requirements for speed, noise, and input impedance without requiring external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 10.6 MHz - enables stable closed-loop gain ≥1 operation up to audio and low RF frequencies |
| Slew rate | 32 V/μs - supports fast transient response in pulse amplification and active filtering |
| Input offset voltage (max) | 4 mV at 25°C - ensures ≤0.1% gain error in 10 V full-scale measurement circuits |
| Supply voltage range | ±2.25 V to ±19 V - accommodates high-dynamic-range signal chains in energy metering and motor control |
| Input bias current (max) | 175 nA - minimizes voltage error across high-impedance sensor sources (e.g., piezoelectric, pH electrodes) |
| Common-mode input range | –10.9 V to +15 V at ±15 V supply - allows direct interfacing to bipolar sensors without level-shifting |
| Total supply current | 11.2 mA typical (2.8 mA per amplifier) - balances performance and power efficiency in multi-channel systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad JFET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL084CDW | Lower bandwidth (4 MHz), higher VIO (15 mV max), no Excalibur process - 3× slower slew rate (13 V/μs) | Acceptable for <100 kHz signal paths but insufficient for oscilloscope front-ends or fast DMM autoranging | Select when cost sensitivity outweighs speed/noise requirements and existing TL084 designs require minimal requalification |
| OPA4134UA | Higher precision (0.5 mV VIO), lower noise (8 nV/√Hz), but narrower supply (±18 V) and lower slew (20 V/μs) | Better for audio and low-frequency precision, less suitable for high-slew industrial transients or wide-supply applications | Choose for battery-powered audio analyzers or medical sensors where ultra-low offset dominates over speed |
Compared with TL084CDW, TLE2084ACDW delivers double bandwidth and half offset voltage while maintaining pin compatibility; versus OPA4134UA, it trades minor noise penalty for significantly higher slew rate and wider supply tolerance - critical for EV charging and power electronics.

FAQ
What is the maximum supply voltage rating for TLE2084ACDW?
The TLE2084ACDW supports dual supplies from ±2.25 V to ±19 V, with absolute maximum ratings of ±38 V across VCC+ and VCC– terminals. Operation beyond ±19 V is not recommended, as specified in Section 6.1 of the datasheet, and may compromise long-term reliability or parametric guarantees.
Does TLE2084ACDW have the same pinout as TL084DW?
Yes, TLE2084ACDW uses identical SOIC-16 pinout and terminal functions as TL084DW, including matching IN+, IN–, OUT, VCC+, and VCC– positions. This enables direct drop-in replacement in legacy TL084-based designs without PCB modification or layout changes.
What is the input offset voltage specification for TLE2084ACDW at 25°C?
The TLE2084ACDW has a maximum input offset voltage of 4 mV at 25°C, as confirmed in Table 4-3 of the datasheet for the "TLE2084ACDW" ordering option under the C-suffix (0°C to 70°C) temperature grade. Typical value is 0.65 mV.
Can TLE2084ACDW drive a 600 Ω load effectively?
Yes, TLE2084ACDW delivers ≥80 dB large-signal open-loop gain into 600 Ω loads at ±5 V and ±15 V supplies, and maintains ≥±13.5 V output swing at ±15 V with 2 mA load - sufficient for driving legacy video lines, RF detector stages, and standard test equipment inputs.
Is TLE2084ACDW suitable for use in battery-powered portable instruments?
Yes, TLE2084ACDW draws only 2.8 mA per amplifier (11.2 mA total) at ±5 V, enabling multi-channel analog front-ends in portable DMMs and handheld oscilloscopes. Its 4 mV VIO and low 1/f noise also reduce calibration frequency and extend usable battery life between recalibrations.
