STMICROELECTRONICS JFET Operational Amplifier, 1 Channel, 4MHz, SOIC-8

The STMICROELECTRONICS Low Noise JFET Operational Amplifier is a high-performance single-channel monolithic integrated circuit that incorporates well-matched, high-voltage JFET and bipolar transistors. Designed for general-purpose amplification, this device features high slew rates, low input bias and offset currents, and a low offset voltage temperature coefficient, making it an excellent choice for precision applications.

Key Features

• Wide common-mode (up to VCC+) and differential voltage range
• Low input bias and offset current
• Low noise: en = 15nV/√Hz (typ)
• Output short-circuit protection
• High input impedance JFET input stage
• Low harmonic distortion: 0.01% (typ)
• Internal frequency compensation
• Latch-up free operation

Applications and Benefits

With a gain bandwidth product of 4MHz and a typical slew rate of 16V/µs, this operational amplifier delivers reliable performance across a supply voltage range of 6V to 36V. The high input impedance JFET input stage ensures minimal signal loading, whilst the internal frequency compensation simplifies circuit design. Housed in a compact SOIC-8 surface-mount package, it operates reliably in temperatures ranging from -40°C to 105°C, making it suitable for demanding industrial environments.
