Product details
Overview
TLE2084ACN 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 maximum 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 TLE2084ACN datasheet, TLE2084ACN pinout, TLE2084ACN application, or TLE2084ACN equivalent, key selection considerations include its 14-pin PDIP package, rail-to-rail output swing under ±15 V operation, low 28 nV/√Hz input voltage noise at 1 kHz, and guaranteed performance across 0°C to 70°C ambient temperature.
Technical Context
The TLE2084ACN implements a high-voltage JFET input stage enabling wide common-mode range (–10.9 V to +15 V at ±15 V supplies) and low input bias current (≤175 nA). Its internal compensation ensures stable unity-gain operation with ≥56° phase margin into 2 kΩ loads and 25 pF capacitive loads.
Designed for high-fidelity analog signal paths, it delivers 0.0032% THD+N at 1 kHz with 3 VRMS output into 10 kΩ, supports 2 V step settling to 1 mV in 1.5 μs at ±15 V, and maintains 120 dB crosstalk attenuation between adjacent amplifiers in the quad configuration.
Key Specifications

| Unity-gain bandwidth | 10.6 MHz - enables stable closed-loop gain ≥1 with bandwidth up to 10.6 MHz |
| Slew rate | 32 V/μs - supports full-scale 10 VPP output at 1.6 MHz without slewing distortion |
| Input offset voltage | 4 mV max at 25°C - limits DC error to ≤4 mV in precision sensor interface or reference buffer circuits |
| Supply voltage range | ±2.25 V to ±19 V - accommodates wide dynamic signal range in industrial power monitoring and battery-powered test equipment |
| Input voltage noise | 28 nV/√Hz at 1 kHz - preserves SNR in low-level signal amplification before ADC input stages |

FAQ
What is the maximum supply voltage rating for the TLE2084ACN?
The TLE2084ACN supports a total supply voltage (VCC+ – VCC–) up to 38 V, with individual rails rated from ±2.25 V to ±19 V. This allows operation at ±15 V for standard industrial systems or ±19 V for extended dynamic range in high-voltage sensing applications without exceeding absolute maximum ratings.
Does the TLE2084ACN support unity-gain stable operation?
Yes, the TLE2084ACN is internally compensated for unity-gain stability, delivering ≥56° phase margin with 2 kΩ load and 25 pF capacitive load. This eliminates need for external compensation components in buffer, follower, or active filter configurations using the TLE2084ACN.
How does the TLE2084ACN compare to TL084 in terms of pin compatibility?
The TLE2084ACN uses identical 14-pin PDIP pinout and terminal functions as TL084CN, including matching channel assignments, power pins, and input/output locations. This enables direct physical and electrical replacement of TL084CN in existing designs without PCB changes.
What is the input offset voltage specification for the TLE2084ACN at room temperature?
The TLE2084ACN has a maximum input offset voltage of 4 mV at 25°C, significantly tighter than the 10 mV typical maximum of standard TL084 variants. This reduces DC error in precision gain stages and improves accuracy in sensor signal chains where TLE2084ACN is deployed.
Can the TLE2084ACN drive capacitive loads commonly found in oscilloscope probe interfaces?
Yes, the TLE2084ACN maintains stability into 25 pF capacitive loads with ≥56° phase margin at unity gain. Its robust output stage supports direct connection to coaxial cables and passive probe networks typical in oscilloscope front-end designs using the TLE2084ACN.
