BA10358

Overview

The BA10358 is a dual operational amplifier manufactured by Rohm Semiconductor using bipolar technology. It features two independent high-gain channels with built-in frequency compensation. The device supports single-supply operation from 3V to 32V or dual-supply operation from ±1.5V to ±16V. Key electrical specifications include a typical quiescent current of 0.7mA, a gain-bandwidth product of 500kHz, and a slew rate of 0.2V/µs. Input offset voltage is typically 2mV with a maximum of 7mV. The input bias current is typically 45nA. The output can source and sink up to 20mA per channel. Operating temperature ranges from -40°C to +85°C.

Feature Summary

• Supports single power supply operation with extremely low current dissipation that remains constant regardless of the supply voltage.
• Input and output voltages are compatible with ground level (ground sense), allowing signals to swing near VEE.
• Pin assignments are identical to the general-purpose 4558 model, ensuring compatibility with other manufacturers' 358 series amplifiers.

Applications

• General-purpose analog signal processing circuits
• Audio pre-amplification stages
• Sensor signal conditioning

Procurement Notes

Verify the specific package variant required for the design, as the BA10358 family includes DIP-8, SOP-8, SSOP-B8, and SIP-8 options. Confirm RoHS compliance status if environmental regulations apply to the end product. Check component availability as some variants may be marked as not recommended for new designs. Ensure the selected package matches the PCB footprint and thermal requirements defined in the datasheet.

Selection Notes

Select this component when a cost-effective, dual-channel op-amp with wide voltage range and ground-sense capability is needed. It serves as a direct pin-compatible replacement for standard 4558 or LM358 equivalents. Consider the 0.2V/µs slew rate and 500kHz bandwidth limits for high-speed applications where faster response times are required.

Part Context

The BA10358 belongs to Rohm's standard linear IC portfolio designed for general-purpose amplification. It utilizes a monolithic bipolar process to integrate two independent operational amplifiers on a single die. The series provides multiple packaging options to accommodate different mounting styles, including through-hole and surface-mount technologies, facilitating integration into various electronic systems.
