BU7295HFV-TR

Overview

The BU7295HFV-TR is a single-channel, low-voltage CMOS operational amplifier manufactured by ROHM Semiconductor. It operates within a supply voltage range of 1.8 V to 5.5 V and consumes 150 µA of operating current. Key electrical parameters include a gain-bandwidth product of 1 MHz, a slew rate of 1 V/µs, and an input offset voltage of 1 mV. The device features an input bias current of 1 pA, an output current capability of 8 mA per channel, a common-mode rejection ratio of 45 dB, and a power supply rejection ratio of 60 dB. It is housed in a 5-HVSOF surface-mount package and functions across a temperature range of -40°C to +85°C.

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, as variations such as cut tape or reel may affect handling requirements. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure that the selected variant matches the required thermal and electrical specifications for the target application environment. Cross-reference the manufacturer part number with distributor catalogs to validate authenticity and availability.

Selection Notes

Select this component when design constraints demand a balance between low power consumption and moderate speed performance. The 1 MHz bandwidth and 1 V/µs slew rate suit applications where high-frequency precision is not critical but energy efficiency is paramount. Consider the 5-HVSOF package size for space-constrained PCB layouts. Evaluate the 1 mV input offset voltage against system accuracy requirements to determine if external calibration is necessary.
