Overview
The BU5281G-TR is a single-channel, ground-sense CMOS operational amplifier manufactured by Rohm Semiconductor. It operates on a single supply voltage ranging from +1.8V to +5.5V with a typical supply current of 750µA. The device features a slew rate of 2.0V/µs and a unity gain frequency of 3MHz. Key electrical characteristics include an input offset voltage of ±2.5mV (max) and an input bias current of 1pA (typ). It provides full-swing output capability within the SSOP5 package.
Feature Summary
- Ground sense input capability allowing operation down to the negative supply rail
- Full-swing output stage maximizing dynamic range at low voltages
- Low input bias current suitable for high-impedance sensor interfaces
- Single-supply operation optimized for portable battery-powered equipment
Applications
- Sensor Amplifier
- Active Filter
- Buffer
- Mobile Equipment
Procurement Notes
Verify the specific suffix 'G' corresponds to the -40°C to +85°C operating temperature range. Confirm the 'TR' suffix indicates embossed tape and reel packaging. Ensure the design accounts for the absolute maximum ratings regarding reverse polarity and input voltage limits to prevent latch-up or damage during procurement validation.
Selection Notes
Select this component when a ground-referenced input is required alongside low-voltage compatibility. The MOSFET input structure offers extremely low bias current, making it distinct from bipolar alternatives. Verify that the 3MHz bandwidth and 2V/µs slew rate meet the signal processing requirements for the intended application circuit.
Part Context
This part belongs to the BU5281xx series of low input offset voltage, ground sense CMOS operational amplifiers. The 'BU5281G' variant specifically denotes the standard industrial temperature grade (-40°C to +85°C), while the 'S' suffix indicates the extended automotive-grade temperature range (-40°C to +105°C). Both share identical pinouts and electrical performance profiles.
Replacement Considerations
The BU5281SG-TR serves as the extended temperature version of this component. Designers requiring operation above +85°C should substitute the G suffix with S. No other direct cross-manufacturer equivalents are confirmed in the provided documentation.
