What are the key features of BUF602IDG4?
- 700 MHz -3dB bandwidth with 1000 V/µs slew rate enables high-frequency signal buffering for ADC input drivers and test equipment without bandwidth degradation
- Dual-supply operation from ±6.3V to ±12.6V supports both standard ±5V and ±12V analog system rails in a single 8-pin SOIC package
- Unity-gain stable open-loop buffer isolates sensitive signal sources from capacitive loads up to 1000 pF while maintaining signal integrity at high frequencies
What is BUF602IDG4 used for?
The BUF602IDG4 is designed for high-speed signal distribution in RF test equipment, oscilloscope front-ends, and precision data acquisition systems where a signal source must drive multiple ADC inputs or long PCB traces without signal degradation above 100 MHz. Its 1000 V/µs slew rate and 700 MHz bandwidth make it suitable as a unity-gain output buffer after a precision op amp in a signal chain, decoupling the precision amplifier from reactive loads that would otherwise reduce its settling time. The ±6.3V to ±12.6V supply range ensures compatibility with both ±5V and ±12V analog power rails common in laboratory instrumentation and industrial measurement systems.

Frequently Asked Questions
What slew rate and bandwidth does the BUF602IDG4 provide, and how does this support ADC input driving at 100 MSPS?
The BUF602IDG4 delivers a 1000 V/µs slew rate and 700 MHz -3dB bandwidth. For a 100 MSPS ADC requiring a full-scale 2V step settled to 0.1% in under 5 ns, the 1000 V/µs slew rate produces a 2V transition in 2 ns, well within the settling budget. The 700 MHz bandwidth ensures less than 3 dB attenuation for analog input signals up to 200 MHz when the ADC's Nyquist frequency requires bandwidth up to 50 MHz with comfortable margin.
How much capacitive load can the BUF602IDG4 drive without significant bandwidth degradation?
The BUF602IDG4 is specified to drive capacitive loads up to 1000 pF while maintaining stable unity-gain operation without oscillation. Beyond 1000 pF, a small series resistor of 10 Ω to 33 Ω at the output isolates the load capacitance from the buffer's output stage, reducing the phase shift that causes peaking. This makes it suitable for driving long coaxial cables (50-100 pF per meter) or large ADC sample-and-hold capacitors in data acquisition front-ends.
Which supply voltage rails are compatible with the BUF602IDG4, and can it operate from a single-supply 12V rail?
The BUF602IDG4 requires dual bipolar supply rails ranging from ±6.3V (12.6V total) to ±12.6V (25.2V total). It is not designed for single-supply operation; a single 12V rail would provide only ±6V referred to the virtual mid-supply, which is below the ±6.3V minimum. For single-supply applications, a virtual ground generator splitting 12V into ±6V is technically marginal — the full ±12V supply (±6V split from a 24V single supply) is recommended for full-performance operation at 1000 V/µs slew rate.
