BU7465SHFV-TR

Overview

The BU7465SHFV-TR is a single-channel CMOS operational amplifier manufactured by ROHM Semiconductor. It features a gain-bandwidth product of 1.2 MHz and a slew rate of 1 V/µs. The device operates within a supply voltage range of 1.7 V to 5.5 V, with a typical circuit current consumption of 120 µA. It provides an output current of 18 mA per channel and exhibits a low input bias current of 1 pA. The input offset voltage is specified at 1 mV. Packaged in a compact 5-HVSOF format, it supports surface mount installation and functions reliably across an operating temperature range from -40°C to +105°C.

Feature Summary

• Ground-sense input capability allowing operation down to the negative supply rail
• Full-swing output design maximizing dynamic range in low-voltage applications
• Ultra-low input bias current characteristic suitable for high-impedance signal sources

Applications

• Battery-powered portable electronic devices requiring extended runtime
• Low-voltage sensor signal conditioning circuits
• Industrial control systems utilizing single-supply architectures
• Consumer electronics with strict power consumption constraints

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to ensure correct packaging and electrical tolerances. Confirm that the intended application environment remains within the specified thermal limits. Check for any automotive qualification restrictions as standard grade products may not be suitable for vehicle-mounted equipment. Ensure compatibility with the target PCB footprint dimensions.

Selection Notes

Select this component when ground-referenced input signals are required without level shifting. Compare performance metrics against other members of the BU7465 series if higher speed or additional channels are needed. Evaluate the trade-off between the 1.2 MHz bandwidth and the low 120 µA quiescent current. Consider the HVSOF package size constraints during layout planning.
