Texas Instruments LM158FKB Dual Operational Amplifier

The LM158FKB is a high-performance, dual operational amplifier (op-amp) designed by Texas Instruments, a leader in semiconductor design and manufacturing. This op-amp is part of the LMx58 series, which are known for their versatility and reliability in a wide range of electronic applications.

The LM158FKB features two independent, high-gain, internally frequency-compensated operational amplifiers, which are designed specifically to operate from a single power supply over a wide range of voltages. However, the device can also be configured to operate from split power supplies, providing design flexibility.

With its low supply current drain, this op-amp is suitable for battery-powered devices and other power-sensitive applications. The common-mode input range includes the negative supply, thereby eliminating the need for external biasing components in many applications. The device also offers full-wave rectification without using a diode bridge, thanks to its capability to directly drive the rectifier.

Key features of the LM158FKB include:

• Wide power supply range: Single supply 3V to 32V, or dual supplies ±1.5V to ±16V
• Low supply current drain independent of the power supply voltage: 500 μA
• Low input biasing current: 45 nA (typical)
• Low input offset voltage and offset current
• Differential input voltage range equal to the power supply voltage
• Open-loop differential voltage amplification: high gain
• Internal frequency compensation
• Output short-circuit protection

The LM158FKB is typically housed in a TO-99 metal can package, which ensures robustness and thermal performance, making it ideal for industrial environments. Its applications span across conventional op-amp circuits, including transducer amplifiers, dc gain blocks, and all the conventional op-amp circuits that now can be more easily implemented in single power supply systems.

For engineers and designers looking for a reliable and efficient solution for their analog circuit needs, the LM158FKB from Texas Instruments offers the performance and versatility required for a wide array of electronic designs.
