BU7294F-E2

Overview

The BU7294F-E2 is a four-channel CMOS operational amplifier manufactured by ROHM Semiconductor. It features high-speed input-output full-swing operation with a gain-bandwidth product of 2.8 MHz and a slew rate of 3 V/us. The device operates on a single power supply ranging from 2.4 V to 5.5 V, consuming approximately 2 mA per channel. Key electrical characteristics include an input offset voltage of 1 mV, input bias current of 1 pA, output current of 8 mA, common-mode rejection ratio of 40 dB, and power supply rejection ratio of 45 dB. It is housed in an SSOP-14 package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Supports full-amplitude input and output voltage swings relative to the power supply rails.
• Delivers high-speed performance with a 3 V/us slew rate for rapid signal transitions.
• Maintains extremely low input bias current of 1 pA for minimal loading effects.

Applications

• Signal conditioning in portable battery-powered devices
• Sensor interface circuits requiring low bias current
• General-purpose analog signal processing

Procurement Notes

Verify the exact suffix against official ROHM documentation, as the provided model references an E2 variant while source data highlights the FV configuration. Confirm RoHS compliance status and specific packaging quantities directly with the manufacturer or authorized distributors. Ensure the selected component matches the required operating temperature range and pinout compatibility for your design.

Selection Notes

Select this component when full-signal swing capability is required at low voltages. The 2.8 MHz bandwidth suits moderate-speed applications. Compare against other BU72xx series variants if higher precision or different channel counts are needed. Verify that the 8 mA output drive meets load requirements without external buffering.

Part Context

This part belongs to the BU7294 family of CMOS operational amplifiers designed for low-voltage, low-power applications. The series emphasizes rail-to-rail input and output capabilities alongside high speed. It is distinct from the BU726x series which focuses on ultra-low current consumption rather than high slew rates.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Consult ROHM technical support for direct equivalents or functional replacements within the BU72xx series.
