LM358BP - Dual Operational Amplifier | Texas Instruments
The Texas Instruments LM358BP is a dual operational amplifier in an 8-pin surface-mount package, combining two independent amplifiers for general-purpose analog signal conditioning. The LM358BP is associated with the LM358 family, a low-power dual op-amp solution designed for applications requiring wide supply-voltage range, high open-loop gain, and straightforward single-supply operation. The verified manufacturer information identifies the LM358 family as a dual operational amplifier offering low power consumption, high gain, and a wide voltage range, while the LM358B device is specified as a dual, 36-V, 1.2-MHz, 3-mV-offset operational amplifier with an operating-temperature range of -40°C to 85°C.
An operational amplifier is an active semiconductor device that uses differential input voltage to control an output voltage. A dual operational amplifier contains two amplifier sections in one package, allowing designers to implement two signal-processing channels while reducing board area and component count. The LM358BP is therefore useful in sensor interfaces, transducer amplifiers, voltage comparators, current-monitoring circuits, audio preamplifier stages, and general feedback-control circuits. Its dual architecture can also simplify designs in which two independent amplifier functions are required at similar supply and performance levels.
The LM358B family is described by Texas Instruments as a dual, 36-V operational amplifier with 1.2-MHz bandwidth and 3-mV maximum offset voltage. The LM358BP ordering code identifies the specific package and ordering variant of this family. The verified distributor listing describes the device as a standard or general-purpose amplifier with two circuits, and identifies the package as an 8-pin micro PBGA surface-mount package. Because the exact package dimensions, pin assignments, and full electrical limits are not included in the manufacturer result excerpts used for this page, individual electrical values should be confirmed against the manufacturer datasheet before final circuit release.
The LM358 family is commonly associated with low-power operation, high gain, and a wide operating-voltage range. In practical designs, the amplifier can be used with single-supply systems where the input and output signals remain within the common-mode and output-swing limits. The LM358BP is appropriate where two channels are needed and where a simple, widely understood dual-op-amp architecture is preferable to a more specialized precision or high-speed amplifier.
Typical applications include resistive sensor conditioning, buffered instrumentation inputs, low-frequency audio amplification, comparator functions, and general feedback amplifiers. The device can reduce board area by providing two amplifiers in one package, while the family-level supply range supports operation from conventional single-supply rails. Designers should still verify input common-mode range, output swing, output-current capability, noise, offset drift, and stability requirements against the complete LM358B datasheet.
For PCB implementation, use the manufacturer land pattern for the LM358BP package rather than substituting a generic SOIC-8 footprint. Place input, output, and supply bypass capacitors close to the relevant pins, maintain a short return path for ground currents, and avoid routing sensitive input traces beside the output stage. This page combines manufacturer family information, distributor identification, drop-in alternatives, application guidance, and design considerations to support component selection and PCB planning.
