BUF634AIDR

Overview

The BUF634AIDR is a high-speed buffer amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 210 MHz and a slew rate of 1900 V/µs. The device delivers an output current of 250 mA with a supply voltage range of 4.5 V to 36 V. Input bias current is typically 5 µA, and input offset voltage is 30 mV. It operates within a temperature range of -40°C to +85°C and is housed in an 8-pin SOIC package.

Feature Summary

• Provides high-speed signal buffering with a 210 MHz gain-bandwidth product for maintaining signal integrity at high frequencies.
• Delivers substantial drive capability through a 250 mA output current capacity suitable for demanding load applications.
• Features low input bias current and moderate input offset voltage to minimize signal distortion in precision circuits.

Applications

• Video signal distribution and buffering
• High-speed data acquisition systems
• RF and IF signal processing stages

Procurement Notes

Verify the specific suffix 'AIDR' corresponds to the industrial temperature grade (-40°C to +85°C) and SOIC-8 packaging. Confirm that the manufacturer's datasheet specifies the exact electrical characteristics for this variant, as performance parameters may vary between different sub-models within the BUF634 family. Ensure compatibility with your system's power supply voltage limits.

Selection Notes

Select this component when a single-channel buffer requires both high bandwidth and significant current drive capability. Compare against other BUF634 variants if higher operating temperatures or different package styles are required. Consider the trade-off between the 210 MHz bandwidth and the 250 mA output current relative to your specific application needs.

Part Context

This part belongs to the BUF634 series of high-speed buffer amplifiers from Texas Instruments. The series includes various packages and temperature grades, such as the TO-263 and SON options. The BUF634AIDR specifically denotes the industrial grade version in surface-mount SOIC packaging, designed for robust performance in standard commercial and industrial environments.

Replacement Considerations

Direct substitutes include other BUF634 variants like the BUF634F/500 for different package requirements. Verify pinout compatibility before replacing with non-Texas Instruments equivalents, as internal architecture differences may affect stability and drive capability.
