BD7541G-TR

Overview

The BD7541G-TR is a single-channel, low-power CMOS operational amplifier manufactured by ROHM Semiconductor. It operates within a supply voltage range of +5.0 V to +14.5 V on a single supply or ±2.5 V to ±7.25 V on a dual supply. Key electrical specifications include a gain-bandwidth product of 600 kHz, a slew rate of 0.3 V/µs, and a typical supply current of 180 µA per channel. The device features rail-to-rail input and output capabilities, an input offset voltage of 1 mV, and an input bias current of 1 pA. It is housed in a 5-pin SSOP package.

Feature Summary

• Supports high-voltage operation with a wide supply range from +5 V to +14.5 V.
• Provides full swing input and output voltage ranges relative to the supply rails.
• Features extremely low input bias current for minimal loading effects.
• Designed for low power consumption with reduced operating current.

Applications

• Battery-powered instrumentation circuits
• Signal conditioning for sensor interfaces
• General-purpose analog signal processing

Procurement Notes

Verify the specific suffix (e.g., TR) against the manufacturer's datasheet to confirm packaging type and reel specifications. Ensure the component status is active for new designs, as some variants may be marked as not recommended for new use. Cross-reference the pinout and thermal characteristics with the official ROHM documentation before finalizing procurement orders.

Selection Notes

Select this component when a single op-amp with rail-to-rail performance is required under moderate supply voltages. It is suitable for applications prioritizing low quiescent current over high-speed signal processing. Compare its 600 kHz bandwidth against higher-speed alternatives if rapid transient response is critical. Verify that the 1 mA output drive capability meets the load requirements of the target circuit.

Part Context

This part belongs to the BD7541/BD7561 family of high-voltage CMOS operational amplifiers. The family integrates phase compensation capacitors internally, simplifying external circuit design. These devices are characterized by their ability to operate efficiently across a broad temperature range while maintaining stable performance in single-supply configurations.

FAQ
