Product details
Overview
TLE2084CDW from Texas Instruments is a quad high-speed JFET-input operational amplifier with 10.6 MHz unity-gain bandwidth, 32 V/μs slew rate, and ±19 V supply capability. It delivers low input offset voltage (7 mV max), low noise (7 nV/√Hz at 1 kHz), and high common-mode rejection (85 dB), making it suitable for precision signal conditioning in oscilloscopes, data acquisition systems, and industrial metering.
For engineers reviewing the TLE2084CDW datasheet, TLE2084CDW pinout, TLE2084CDW application, or TLE2084CDW equivalent, key selection criteria include its SOIC-16 package, quad-channel configuration, ±2.25 V to ±19 V operating range, 32 V/μs slew rate, and compatibility with legacy TL084 designs while offering double the bandwidth.
Technical Context
The TLE2084CDW uses JFET-input stages to achieve high input impedance (>100 MΩ common-mode, >6 TΩ differential) and low input bias current (≤175 nA). Its internal compensation ensures stable unity-gain operation with 56°–57° phase margin and supports fast settling (0.4 μs to 10 mV on a 10 V step).
It operates across 0°C to 70°C ambient temperature with specified performance at ±5 V and ±15 V supplies, delivering rail-to-rail output swing capability (±14.5 V at 20 mA load) and robust 65 mA short-circuit output current per channel.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad high-speed JFET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL084CDR | 5 MHz bandwidth, 13 V/μs slew rate, 15 mV max VIO, same SOIC-16 pinout | Limited to lower-speed signal paths; insufficient for >5 MHz acquisition or fast-settling filters | Select when cost sensitivity outweighs bandwidth and noise requirements |
| OPA4134UA | FET-input, 8 MHz bandwidth, 20 V/μs slew rate, 0.5 mV max VIO, SOIC-14 package | Higher precision but non-pin-compatible; requires PCB redesign and layout validation | Choose for ultra-low offset and distortion where layout change is acceptable |
Compared with TL084CDR, TLE2084CDW doubles bandwidth and slew rate while halving input offset; versus OPA4134UA, it offers pin compatibility with legacy designs but trades off some DC precision for broader supply range and higher output drive.

FAQ
What is the maximum supply voltage rating for the TLE2084CDW?
The TLE2084CDW supports a total supply voltage (VCC+ to VCC−) of up to 38 V, enabling operation from ±2.25 V to ±19 V. This wide range allows direct use in high-dynamic-range applications such as oscilloscope front-ends and industrial power monitoring circuits without external level-shifting components. The absolute maximum rating is strictly limited to 38 V; exceeding this risks permanent damage to the TLE2084CDW.
Is the TLE2084CDW pin-compatible with the TL084 series?
Yes, the TLE2084CDW is fully pin-compatible with the TL084 in the SOIC-16 (DW) package. All 16 pins-including channel inputs, outputs, and supply terminals-match the TL084 pinout exactly. This allows drop-in replacement in existing designs, delivering immediate performance gains (2× bandwidth, lower noise, tighter offset) without PCB modification. The TLE2084CDW retains identical footprint and thermal characteristics as the TL084CDW.
What is the typical input offset voltage of the TLE2084CDW at room temperature?
The typical input offset voltage of the TLE2084CDW is 0.49 mV at 25°C with ±15 V supplies, and 0.34 mV with ±5 V supplies. The maximum guaranteed value across the 0°C to 70°C operating range is 7 mV. This specification is confirmed in the TLE2084C Electrical Characteristics tables (Sections 6.6 and 6.14 of the datasheet), and applies directly to the TLE2084CDW variant.
Does the TLE2084CDW support operation at elevated temperatures?
No-the TLE2084CDW is rated only for 0°C to 70°C ambient operation (C-suffix grade). For extended temperature ranges, engineers must select the TLE2084IDW (–40°C to 85°C) or TLE2084MDW (–55°C to 125°C). The C-suffix designation in TLE2084CDW explicitly defines its commercial temperature grade, and operation outside 0°C–70°C is not characterized or guaranteed for this part number.
How does the noise performance of the TLE2084CDW compare between ±5 V and ±15 V supply conditions?
At ±15 V supply, the TLE2084CDW achieves 7 nV/√Hz input voltage noise at 1 kHz, improving from 28 nV/√Hz at ±5 V. This reduction results from optimized internal biasing under higher supply conditions and is documented in Sections 6.5 (±5 V) and 6.7 (±15 V) of the datasheet. The lower noise at ±15 V makes the TLE2084CDW especially effective in high-voltage precision applications like energy metering and oscilloscope front-ends.
