Product details
Overview
TLE2084IDW 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 AC signal conditioning stages of oscilloscopes, data acquisition systems, and industrial metering.
For engineers reviewing the TLE2084IDW datasheet, TLE2084IDW pinout, TLE2084IDW application, or TLE2084IDW equivalent, this page delivers verified electrical characteristics, SOIC-16 package terminal mapping, real-world use cases in high-dynamic-range analog front-ends, and validated alternative options for design continuity.
Technical Context
The TLE2084IDW integrates four independent high-voltage JFET-input op-amps on a single die, each featuring low input bias current (≤175 nA), low noise (7 nV/√Hz at 1 kHz with ±15 V supplies), and stable unity-gain operation with 56°–57° phase margin. Its architecture supports rail-to-rail output swing within ±14.5 V at 20 mA load under ±15 V supplies.
Designed for wide-supply applications, it operates across –40°C to +85°C with guaranteed performance at ±2.25 V to ±19 V supply rails. Input common-mode range extends to within 1.9 V of either rail at ±5 V supplies and to within 10.9 V at ±15 V supplies, enabling robust signal handling in bipolar sensor interfaces.

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 |
|---|---|---|---|
| TL084CDR | Lower 3 MHz bandwidth, 13 V/μs slew rate, ±15 V max supply, 15 mV VIO (max) | Acceptable for lower-speed metering and audio preamp where bandwidth <5 MHz suffices | Select when cost sensitivity outweighs speed/noise requirements and existing layout uses SOIC-14 |
| OPA4134UA | 10 MHz bandwidth, 20 V/μs slew rate, ±18 V supply, 1.5 mV VIO (max), FET input | Better DC precision and lower distortion, but higher quiescent current (4 mA/ch vs. 2.8 mA/ch) | Prefer for high-fidelity audio or precision DC-coupled systems where offset and THD dominate |
Compared with TL084CDR, TLE2084IDW delivers >2× bandwidth and tighter offset spec while maintaining SOIC-16 compatibility; versus OPA4134UA, it trades slightly higher noise for lower power and broader supply tolerance-making it optimal for industrial-grade mixed-signal front-ends.

FAQ
What is the maximum supply voltage rating for the TLE2084IDW?
The TLE2084IDW supports a total supply voltage (VCC+ to VCC–) of up to 38 V, corresponding to ±19 V operation. This rating is confirmed in Section 6.1 Absolute Maximum Ratings of the TI datasheet (SLOS182C). Exceeding ±19 V risks permanent damage. The device operates reliably across ±2.25 V to ±19 V per the Recommended Operating Conditions table.
Does the TLE2084IDW have rail-to-rail input or output capability?
The TLE2084IDW does not feature rail-to-rail input or output. Its input common-mode range extends to within 1.9 V of either supply at ±5 V and within 10.9 V at ±15 V. Output swing reaches ±14.5 V into 20 mA loads with ±15 V supplies-leaving ~0.5 V headroom to each rail. These values are specified in Tables 6.4–6.15 of the official datasheet.
What is the typical input offset voltage of the TLE2084IDW at room temperature?
The typical input offset voltage of the TLE2084IDW is 0.47 mV at 25°C under ±15 V supplies, as documented in Table 6.10 (TLE2081I Electrical Characteristics, extended to TLE2084 via family specification). The maximum guaranteed value is 4 mV at 25°C, per the "TLE2084 Available Options" packaging table for the 'I' grade (–40°C to +85°C).
Can the TLE2084IDW replace TL084 in an existing SOIC-14 footprint?
No-the TLE2084IDW uses a SOIC-16 package (DW), while TL084 is commonly offered in SOIC-14 (D) or PDIP-14 (N). Pin count and spacing differ: TLE2084IDW has 16 pins with 1.27 mm pitch and two NC pins (8 and 9), whereas TL084SOIC-14 has 14 pins. Direct replacement requires PCB layout revision to accommodate the larger SOIC-16 footprint and routing changes.
What is the unity-gain stable bandwidth and phase margin of the TLE2084IDW?
The TLE2084IDW has a unity-gain bandwidth of 10.6 MHz and a phase margin of 56°–57° at unity gain with 25 pF capacitive load and 2 kΩ load resistance, as measured per Section 6.5 and 6.11 of the datasheet. These values ensure stable operation in unity-gain follower and active filter configurations without external compensation.
