Descriptions:_x000D_ AD8367 was introduced by AD company as a variable gain single-ended IF amplifier, which uses AD's advanced X-AMP structure, with excellent gain control features. Because of the integrated on-chip rfc geophone, it is also the world's first VGA chip that enables single-chip closed-loop AGC. The chip features a high performance 45dB variable gain amplifier that controls linear gain and operates stably from any low frequency to 500MHz. _x000D_ _x000D_ _x000D_ Features: _x000D_ Single-ended input, single-ended output. _x000D_ Input impedance is 200, the output impedance is 50. _x000D_ 3dB bandwidth is 500MHz. _x000D_ When the input is zero level, the output level is half of the supply voltage, and adjustable. _x000D_ Gain control feature selection and power-down control. _x000D_ On-chip integrated square root detector, can achieve single-chip AGC applications. _x000D_ Gain control characteristics in dB linear. _x000D_ The operating frequency can be extended to any low frequency by external capacitor. _x000D_ _x000D_ Module Features:_x000D_ 1. Single 5V supply, current 30mA._x000D_ 2. The default is AGC mode, If you want to change to VGA mode, you only need to invert the SW1 jumper, add 0.05-0.95V voltage to control._x000D_ 3. The module default input and output impedance of 50R, can be changed as you needed._x000D_ 4. If you need to obtain greater output voltage, can change part of the partial pressure._x000D_ _x000D_ Package included:_x000D_ _x000D_ 1 x AD8367 Module
