Texas Instruments TLE2082CDG4

Overview

TLE2082CDG4 from Texas Instruments is a dual high-speed JFET-input operational amplifier in SOIC-8 package, delivering 10.6 MHz unity-gain bandwidth, 32 V/μs slew rate, and ±19 V supply capability. It serves as a direct upgrade to TL082 and TL072 in precision AC-coupled signal conditioning stages of oscilloscopes and data acquisition systems.

For engineers reviewing the TLE2082CDG4 datasheet, TLE2082CDG4 pinout, TLE2082CDG4 application, or TLE2082CDG4 equivalent, key selection criteria include input offset voltage (max 6 mV at 25°C), crosstalk attenuation (120 dB), wide common-mode range (±11.9 V at ±15 V supplies), and low input bias current (≤175 nA) for high-impedance sensor interfaces.

Technical Context

The TLE2082CDG4 integrates two matched JFET-input op-amps with high input impedance (>100 MΩ common-mode, 6 TΩ differential), low 1/f noise (2.77 μV_PP, 0.1–10 Hz), and stable phase margin (56° at unity gain). Its architecture supports rail-to-rail output swing under light loads and maintains THD+N ≤ 0.0032% at 1 kHz with 3 V_RMS output.

Designed for dual-channel applications requiring independent signal paths with minimal interaction, it features 120 dB crosstalk attenuation and operates across 0°C to 70°C ambient temperature. The device uses internal compensation for unity-gain stability with 25 pF capacitive load and supports single-supply operation via input common-mode extension down to V_CC– – 0.9 V.

FAQ

What is the maximum supply voltage rating for the TLE2082CDG4?

The TLE2082CDG4 supports a total supply voltage range of ±2.25 V to ±19 V, meaning the absolute maximum difference between VCC+ and VCC– is 38 V. This allows operation in high-dynamic-range applications such as electricity meter front-ends and AC drive voltage monitoring where ±15 V rails are common. Exceeding ±19 V violates Absolute Maximum Ratings and risks permanent damage to the TLE2082CDG4.

Does the TLE2082CDG4 support single-supply operation?

Yes, the TLE2082CDG4 supports single-supply operation. Its input common-mode range extends to VCC– – 0.9 V and VCC+ – 0.9 V at ±5 V supplies, enabling use with as low as 4.5 V total supply (e.g., 0 V and +4.5 V). For reliable operation, ensure input signals remain within this extended common-mode window and verify output swing margins using the VOM+ and VOM– specifications in the TLE2082CDG4 datasheet.

What is the typical crosstalk attenuation between channels in the TLE2082CDG4?

According to the TLE2082CDG4 datasheet, crosstalk attenuation is specified at 120 dB under standard test conditions (VIC = 0 V, RL = 2 kΩ, TA = 25°C). This high isolation ensures minimal signal leakage between the two independent amplifier channels, making the TLE2082CDG4 suitable for dual-path applications like differential oscilloscope inputs or redundant sensor conditioning in flight control units where channel independence is critical.

How does the TLE2082CDG4 compare to the TL082 in terms of bandwidth and slew rate?

The TLE2082CDG4 offers more than double the bandwidth (10.6 MHz vs. 4 MHz) and significantly higher slew rate (32 V/μs vs. 13 V/μs) compared to the TL082. These improvements allow the TLE2082CDG4 to accurately reproduce faster transients and maintain linearity at higher frequencies-key advantages in oscilloscope front-ends and high-speed data acquisition where the TL082 would exhibit gain roll-off and slew-induced distortion.

Is the TLE2082CDG4 RoHS-compliant and lead-free?

Yes, the TLE2082CDG4 is RoHS-compliant and lead-free. Per Texas Instruments' official packaging and environmental documentation, the "G4" suffix denotes green (lead-free) packaging compliant with JEDEC J-STD-020 moisture sensitivity level 3 and RoHS Directive 2011/65/EU. The device uses matte tin lead finish and meets IPC/JEDEC J-STD-020 reflow profile requirements, ensuring compatibility with modern lead-free assembly processes for the TLE2082CDG4.
