Overview
The BUF634UG4 is a high-speed buffer amplifier manufactured by Texas Instruments, belonging to the BUF634 series. It features a single channel with a gain bandwidth product of 180 MHz and a slew rate of 2 kV/us. The device supports a supply voltage range from 4.5 V to 36 V and delivers an output current of 250 mA. Key electrical parameters include an input bias current of 5 uA, an input offset voltage of 30 mV, and an operating supply current of 15 mA. It operates within a temperature range of -40 C to +125 C and is housed in an 8-SOIC package.
Feature Summary
- Provides high-speed buffering capabilities with a 180 MHz gain bandwidth product for signal integrity.
- Delivers a robust 250 mA output current suitable for driving capacitive loads.
- Features low input bias current and low noise density for precision applications.
- Operates reliably across a wide industrial temperature range.
Applications
- Video signal distribution systems
- High-speed data acquisition front-ends
- Driving capacitive loads in test equipment
Procurement Notes
Verify the specific suffix 'G4' against the manufacturer's latest documentation to confirm RoHS compliance status and lead times. Confirm availability as some distributors may list this variant as obsolete or end-of-life. Ensure the SOIC-8 package matches your PCB footprint requirements before ordering.
Selection Notes
Select the BUF634UG4 when a surface-mount solution is required for high-speed buffering applications. Compare its 180 MHz bandwidth and 250 mA drive capability against other variants like the BUF634P or BUF634F/500 to ensure the package and performance metrics align with the design constraints.
Part Context
This component is part of the Texas Instruments BUF634 family of high-speed buffers. It shares core electrical characteristics with through-hole and TO-263 variants but utilizes an 8-SOIC package for surface-mount assembly. The 'G4' suffix typically indicates lead-free and RoHS-compliant manufacturing standards.
Replacement Considerations
Public confirmed substitute part numbers: BUF634U, BUF634AIDR.
