Frequently Asked Questions
What is the bandwidth and output current of the XBUF634AIDR?
The XBUF634AIDR provides a 3dB bandwidth of 210 MHz and a maximum output current of 250 mA. This combination of wide bandwidth and high drive capability makes it ideal for applications that must drive capacitive loads such as ADC inputs, coaxial cables, and transmission lines at high frequencies without significant signal attenuation or bandwidth loss.
What are the supply voltage requirements for the XBUF634AIDR?
The XBUF634AIDR operates from a nominal dual supply of ±15V with a maximum negative supply limit of -20V. This high-voltage supply range provides large signal swing headroom for linear signal processing and makes the device compatible with high-performance test and measurement equipment, industrial signal conditioning systems, and legacy ±15V analog signal chains.
What is the input bias current and input offset voltage of the XBUF634AIDR?
The XBUF634AIDR has a maximum input bias current of 2 µA at 25°C and a maximum input offset voltage of 65000 µV (65 mV). While the offset voltage is relatively high, the buffer is primarily optimized for high-speed, high-current drive performance rather than DC precision, making it best suited for AC-coupled or frequency-domain applications.
What package does the XBUF634AIDR come in?
The XBUF634AIDR is packaged in an 8-pin SOIC (R-PDSO-G8) small outline surface-mount package. This industry-standard package is easy to assemble on PCBs and provides good thermal performance for the 250 mA output current capability. The device was introduced in March 2019 as part of Texas Instruments' extended bandwidth buffer amplifier portfolio.
What applications is the XBUF634AIDR used in?
The XBUF634AIDR is used in video signal distribution, oscilloscope probe buffers, function generator output stages, ADC reference voltage buffers, and active filter output drive stages. Its 210 MHz bandwidth is well suited for driving HDMI, HD-SDI, and analog video signals, while the 250 mA output current allows direct driving of 50-ohm and 75-ohm terminated transmission lines without external power amplification.
