The GX8009‘s high slew rate enables a large signal bandwidth of 440 MHz, meeting the requirements of high-resolution video graphics systems. Signal quality remains at a high level across the entire bandwidth, with the worst-case distortion being –40 dBc (250 MHz, G = +10, 1 Vp-p).

The GX8009 can provide a load current of over 175mA. When driving four video loads, it achieves low differential gain and phase error (0.02% and 0.04°, respectively). Its high drive capability is further demonstrated by its ability to provide 10dBm output power, with a spur-free dynamic range (SFDR) of approximately –38dBc at 70MHz. The GX8009 is available in compact SOIC-8 and SOT23-5 packages, with an operating temperature range of –40°C to 85°C.
