Overview
The BU7271G-TR is a single-channel ultra-low supply current operational amplifier manufactured by ROHM Semiconductor. It features a gain-bandwidth product of 90 kHz and a slew rate of 50 V/us. The input offset voltage is 1 mV, with an input bias current of 1 pA. Operating on a power supply range from 1.8 V to 5.5 V, it draws a typical operating current of 8.6 uA per channel. The output current capability is 4 mA, supported by a common-mode rejection ratio of 45 dB and a power supply rejection ratio of 60 dB. It is housed in an SSOP-5 package.
Feature Summary
- Ultra-low supply current consumption for battery-driven applications
- Wide operating voltage range supporting low-voltage systems
- Low input bias current characteristics
Applications
- Portable machines
- Battery-driven application schemes
Procurement Notes
Verify the specific datasheet version against the manufacturer's official documentation to confirm electrical parameters and mechanical dimensions. Ensure the SSOP-5 package type matches the target PCB footprint requirements. Confirm RoHS compliance status as indicated in the latest technical specifications before finalizing procurement orders.
Selection Notes
Select this component for designs requiring minimal quiescent current within a single-supply environment. The wide input voltage range accommodates various low-voltage logic levels. Consider the 1 mV input offset voltage when designing precision circuits, as it may impact accuracy in high-gain configurations compared to higher-performance op-amps.
Part Context
This device belongs to the BU7271 series of ultra-low supply current amplifiers. It is designed for general-purpose applications where power efficiency is critical. The CMOS technology ensures compatibility with standard digital and analog interfaces commonly found in portable consumer electronics.
Replacement Considerations
Consult official substitution guides for compatible single-channel low-power operational amplifiers with similar pinouts and electrical characteristics.
