Key Features
- Analog Linear-in-dB Gain Control: The AD8368 offers a gain range of -12 dB to +22 dB, scaled accurately to 37.5 dB/V with excellent conformance error.
- High Frequency Operation: The amplifier has a 3 dB bandwidth of 800 MHz, nominally independent of the gain setting.
- Automatic Gain Control (AGC): The component can be configured as a complete AGC system with RSSI by pulling the MODE pin low and using the on-board rms detector.
- Low Noise Figure: At maximum gain, the output noise floor is -143 dBm/Hz, corresponding to a 9.5 dB noise figure.
- Power Management: The AD8368 can be fully powered down to <3 mA by grounding the ENBL pin.
- Industrial Temperature Range: Operates over -40°C to 85°C, making it suitable for a wide range of environments.
