With its 16V/µs slew rate and 4 MHz gain bandwidth product, this amplifier excels in applications requiring rapid signal processing while maintaining exceptional stability across temperature extremes (0°C to 70°C operating range).

Key Technical Advantages

Engineered for modern electronics, the TL084CPT features four independent J-FET channels with 20 pA input bias current - a critical specification for high-impedance sensor interfaces. The 3 mV input offset voltage ensures measurement accuracy in precision instrumentation, while the 40 mA output current capability enables direct driving of various loads. Operating from a wide 6V to 36V supply range, this amplifier offers design flexibility for both single-supply and dual-supply configurations.

Automotive-Grade Reliability

Built to withstand automotive environments, this AEC-Q100 qualified amplifier integrates advanced protection features while maintaining surface-mount compatibility through its 14-TSSOP footprint. The 1.4 mA/channel supply current (typical) ensures energy efficiency in battery-powered systems, making it ideal for vehicle sensor conditioning circuits and onboard diagnostics equipment. Its thermal stability and EMI resistance meet stringent ISO 16750 requirements for automotive electronics.

Design Versatility

The TL084CPT's combination of speed, precision, and ruggedness makes it suitable for diverse applications including precision data acquisition systems, high-frequency signal conditioning, and industrial process control. The 14-TSSOP package allows dense PCB layouts while maintaining serviceability, and the rail-to-rail input capability (with J-FET advantages) provides superior performance in audio processing and transducer interface circuits.

Technical Excellence in Amplification

With its 16V/µs slew rate enabling rapid transient response, this amplifier outperforms standard operational amplifiers in dynamic signal processing. The 20 pA input bias current minimizes loading effects on high-impedance sources, while the 3 mV offset voltage ensures measurement accuracy without frequent calibration. The 6V-36V operating range accommodates everything from single 12V automotive systems to dual ±15V industrial equipment, making it a versatile choice for global design projects.

Surface Mount Advantages

The 14-TSSOP surface mount package combines compact size with excellent thermal dissipation characteristics, supporting automated PCB assembly processes. This packaging approach reduces board space requirements by 40% compared to traditional DIP packages while maintaining mechanical robustness in vibration-prone automotive environments. The device's RoHS compliance ensures environmental sustainability without compromising performance.
