BUF634P

Overview

The BUF634P is a high-speed buffer amplifier manufactured by Texas Instruments, housed in an 8-pin PDIP package. It features a single channel with a bandwidth of 180 MHz and a slew rate of 2000 V/µs. The device supports dual supply voltages ranging from ±2.25V to ±18V (maximum 36V total) and delivers an output current of 250 mA. Key electrical parameters include an input bias current of 5 µA, input offset voltage of 30 mV, and a quiescent current of 15 mA. It operates within a temperature range of -40°C to +125°C.

Feature Summary

• Provides high-current drive capability with 250 mA output capacity for demanding load applications.
• Delivers high-speed performance with 180 MHz bandwidth and 2000 V/µs slew rate for fast signal transitions.
• Offers wide supply voltage operation supporting dual supplies up to ±18V for flexible system integration.

Applications

• Driving capacitive loads in video and signal processing circuits
• Acting as a standalone open-loop driver for precision operational amplifiers
• Integration within feedback loops to improve large-signal response

Procurement Notes

Verify the specific manufacturer source and authenticity when sourcing this component, as it may be available through various distributors. Confirm that the PDIP-8 package matches your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Check for any RoHS compliance documentation if required for your manufacturing standards. Validate the part number suffix to ensure correct pinout and electrical characteristics.

Selection Notes

Select the BUF634P when high output current and fast transient response are critical. It is suitable for applications requiring precise buffering without significant signal degradation. Consider the 180 MHz bandwidth for high-frequency signal integrity. Evaluate the thermal performance given the 125°C maximum junction temperature. Compare against other buffer amplifiers if lower power consumption or different packaging is preferred.

Part Context

The BUF634P belongs to the BUF634 series of high-speed buffer amplifiers from Texas Instruments. This series is designed for applications requiring high current drive and fast settling times. The P suffix indicates the PDIP-8 through-hole package variant. It serves as a robust solution for driving heavy loads while maintaining signal fidelity in analog and video systems.
