BD7562SF-E2

Overview

The BD7562SF-E2 is a high-speed, dual-channel CMOS operational amplifier manufactured by ROHM Semiconductor. It operates within a wide supply voltage range of +5.0V to +14.5V on a single supply or ±2.5V to ±7.25V on a dual supply. Key electrical specifications include a gain-bandwidth product of 1 MHz, a slew rate of 0.9 V/µs, and a typical input bias current of 0.001 nA. The device features full swing input and output capabilities, extending from VSS to VDD for inputs and VSS+0.1V to VDD-0.1V for outputs. It is housed in an SOP-8 package with an operating temperature range of -40°C to +105°C.

Feature Summary

• Supports high-voltage operation up to 14.5V with low power consumption and minimal input bias current.
• Enables full-swing input and output signal handling across the entire supply voltage range.
• Integrates internal phase compensation capacitors to simplify circuit design without external components.

Applications

• General-purpose analog signal processing circuits
• Sensor interface amplification stages
• Industrial control system signal conditioning

Procurement Notes

Verify the specific suffix (E2) against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure the SOP-8 package dimensions match the target PCB footprint. Confirm that the application environment remains within the specified -40°C to +105°C operating temperature range. Note that this component is classified as standard grade and is not recommended for automotive equipment applications.

Selection Notes

Select this component when a dual-channel op-amp requires operation at voltages higher than standard 5V logic levels but lower than industrial 30V standards. The 1 MHz bandwidth and 0.9 V/µs slew rate suit moderate-speed applications. Consider the low input bias current for high-impedance sensor interfaces. Verify that the required output swing allows for the 0.1V headroom specified in the datasheet relative to the supply rails.

Part Context

This part belongs to the BD7562 family of high-voltage CMOS operational amplifiers from ROHM. The family includes single-channel variants like the BD7561 and low-power variants like the BD7542. These devices are designed to replace older bipolar op-amps in high-voltage applications, offering lower power dissipation and higher input impedance while maintaining rail-to-rail performance characteristics.

Replacement Considerations

Check for direct substitutes such as the BD7562F if the extended temperature range (-40°C to +105°C) is not required, as the F variant typically supports up to +85°C. Verify pin compatibility before swapping with other dual-channel high-voltage op-amps from different manufacturers.
