GX8009 Compatible AD8009 for Pulse Signal Amplifier

Our common amplifier, a device that can amplify the voltage or power of an input signal, consists of electronic tubes or transistors, power transformers and other electrical components.

Pulse amplifiers are also known as master amplifiers, and their main functions are amplification and shaping. Amplification is to further amplify the output signal of the preamplifier so that it can be processed and analyzed by the circuit behind it. Forming is the preamplifier output of the exponential attenuation pulse signal into a certain shape to meet the requirements of subsequent analysis and measurement settings, which is conducive to work at high count rates, and can further improve the signal-to-noise ratio. For example, pulse splitters in some encoders can amplify a 5V signal to 12V, 24V, 30V or any other signal up to 30.

The GXSC GX8009 is an ultra-high-speed current feedback amplifier with a slew rate of up to 5500 V/μs and a rise time of only 545 ps, making it ideal for use as a pulse amplifier.

GX8009 (AD8009-compatible) Main Features:

- Slew rate: 5500V/µs (4V step, G=+2)

-Rise time: 545ps (2V step, G=+2)

- Large signal bandwidth: 440MHz, G=+2; 320MHz, G=+10

-Small signal bandwidth (-3dB): 1GHz, G=+1; 700MHz, G=+2 0.1% build-up time is: 10ns (2V step, G=+2)

-Supply voltage: +5V to ±5V, supply current: 16mA

The high voltage swing rate of the GX8009 enables a large signal bandwidth of 440MHz to meet the requirements of high-resolution video graphics systems. Signal quality remains high throughout the wide bandwidth, with worst-case distortion of -40dBc (250MHz, G=+10, 1Vp-p). For multi-frequency signal applications, the third-order intermodulation cutoff (3IP) can reach 12dBm.

The GX8009 has the flexibility to be used as a gain stage amplifier in the IF/RF signal chain. the GX8009 is capable of supplying more than 175mA of load current, and can achieve low differential gain and phase error (0.02% and 0.04°, respectively) when driving four video loads. The high drive capability is also reflected in its ability to provide 10 dBm of output power with a spurious-free dynamic range (SFDR) of approximately -38 dBc at 70 MHz.
