High-Performance Automotive J-FET Amplifier for Demanding Applications
STMicroelectronics continues to set industry standards with its TL084BIDT J-FET operational amplifier, a cutting-edge solution engineered for automotive and industrial applications requiring exceptional precision and reliability. This monolithic 4-channel amplifier combines advanced J-FET input technology with automotive-grade ruggedness, delivering consistent performance across extreme operating conditions. With its AEC-Q100 qualification, the TL084BIDT establishes itself as a preferred choice for mission-critical electronic systems in modern vehicles.
Technical Excellence in Amplifier Design
At the core of this device lies STMicroelectronics' proprietary J-FET technology, enabling ultra-low input bias currents of just 20pA while maintaining remarkable bandwidth capabilities. The amplifier's 4MHz gain bandwidth product and 16V/µs slew rate ensure accurate signal processing across a wide range of frequencies. Its 14-SOIC surface-mount package houses four independent amplifier channels, each capable of delivering 40mA output current while operating from a 6V to 36V supply range. This voltage flexibility makes it ideal for both low-voltage sensor interfaces and high-voltage actuator control systems.
The device's automotive optimization shines through its extended -40°C to 105°C operating temperature range, surpassing standard industrial requirements. This thermal resilience, combined with ESD protection circuitry, ensures reliable performance in demanding environments like engine control units, transmission systems, and advanced driver assistance systems (ADAS). The amplifier's low 1mV input offset voltage and 1.4mA per-channel supply current further enhance its precision and energy efficiency.
