Product details
Overview
TLE2084CDWR 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-coupled signal conditioning stages within oscilloscopes, data acquisition systems, and industrial metering front-ends.
For engineers reviewing the TLE2084CDWR datasheet, TLE2084CDWR pinout, TLE2084CDWR application, or TLE2084CDWR equivalent, key selection considerations include its SOIC-16 package, quad-channel layout, ±2.25 V to ±19 V operating range, low 2.4 mA per amplifier supply current, and verified performance in high-slew-rate, wide-dynamic-range analog signal paths.
Technical Context
The TLE2084CDWR implements a JFET-input differential pair with high-impedance inputs (100 MΩ common-mode, 6 TΩ differential), enabling low bias current (15–175 nA) and minimal loading of high-Z sources. Its internal compensation delivers stable unity-gain operation with 56° phase margin and 300 kHz full-output-swing bandwidth.
It supports rail-to-rail output swing within ±1.5 V of rails at 20 mA load and maintains 85 dB CMRR and 82 dB SVR across 0°C to 70°C. The device operates with ±5 V or ±15 V supplies and features 28 nV/√Hz input voltage noise at 1 kHz under ±5 V conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 10.6 MHz - enables stable closed-loop operation up to 10 MHz with gain ≥1 in filter or buffer applications |
| Slew rate | 32 V/μs - supports fast transient response for 2 V step signals settling to 1 mV in 0.4 μs at ±15 V supply |
| Supply voltage range | ±2.25 V to ±19 V - accommodates wide dynamic signal range in industrial power monitoring and audio processing |
| Input offset voltage (max) | 4 mV at 25°C - ensures ≤4 mV DC error in precision DC-coupled amplification without external trimming |
| Supply current per amplifier | 2.4 mA at ±5 V - allows four independent channels in low-power portable instrumentation with <10 mA total quiescent draw |
| Common-mode input range | –10.9 V to +15 V at ±15 V supply - accepts signals near negative rail, critical for single-supply-derived bipolar front-ends |
| Output voltage swing | ±11.5 V at 20 mA load - delivers >23 Vpp linear output into 2 kΩ, suitable for driving ADC drivers and active filters |

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 | Lower 3 MHz bandwidth, 13 V/μs slew rate, 15 mV max VIO, same SOIC-16 pinout | Acceptable for <1 MHz signal paths but insufficient for fast settling or wideband filtering | Select when cost sensitivity outweighs bandwidth and precision requirements |

FAQ
What is the maximum supply voltage for TLE2084CDWR?
The TLE2084CDWR supports a maximum total supply voltage of 38 V, corresponding to ±19 V operation. Absolute maximum ratings specify VCC+ = 38 V and VCC– = 0 V referenced to ground, but recommended operation remains within ±2.25 V to ±19 V per the datasheet's Recommended Operating Conditions table. Exceeding ±19 V risks permanent damage.
Is TLE2084CDWR pin-compatible with TL084CDW?
Yes, the TLE2084CDWR is pin-compatible with TL084CDW in the SOIC-16 (DW) package. Both share identical pin assignments for all 16 terminals-including channel I/O, dual supplies, and NC pins-as confirmed in TI's SLOS182C datasheet Figures 5-3 and 5-4. No PCB modification is needed for drop-in replacement.
What is the input bias current specification for TLE2084CDWR?
The TLE2084CDWR exhibits an input bias current of 15 nA typical and 175 nA maximum at 25°C under ±5 V supply conditions. This JFET-input architecture ensures minimal loading of high-impedance sources such as piezoelectric sensors or photodiode transimpedance nodes, preserving signal integrity in precision analog paths.
Does TLE2084CDWR support unity-gain stable operation?
Yes, the TLE2084CDWR is internally compensated for unity-gain stability, with a measured phase margin of 56° at unity gain and 25°C. It drives capacitive loads up to 25 pF without oscillation and achieves 0.4 μs settling to 1 mV for a 10 V step-validating robust small-signal and large-signal stability in buffer and follower configurations.
What is the operating temperature range for TLE2084CDWR?
The TLE2084CDWR is rated for commercial temperature operation from 0°C to 70°C, indicated by the "C" suffix in its part number. This range aligns with standard industrial ambient conditions and is validated across all electrical characteristics in Sections 6.4–6.7 of the TI SLOS182C datasheet, including offset voltage, slew rate, and output swing performance.
