The AD8318-EP is an enhanced 70dB logarithmic detector/controller with a frequency range of 1 MHz to 8 GHz. It features wide bandwidth, high accuracy, temperature stability, low noise, and fast response.
The AD8318-EP is a demodulating logarithmic amplifier capable of accurately converting an RF input signal to a corresponding decibel-scaled output voltage. It employs progressive compression over a cascaded amplifier chain and operates with a single 5 V supply, consuming typically 68 mA.
| Specified Frequency Range | 1 MHz to 8 GHz |
|---|---|
| +3 dB Dynamic Range (25°C) | 65 dB |
| Supply Voltage | 4.5 V to 5.5 V |
| Quiescent Current (Enabled) | 68 mA |
| Operating Temperature Range | -55°C to +105°C |
The device typically consumes 68 mA when enabled with a 5 V supply.
Power consumption decreases to less than 1.5 mW when the device is disabled.
The logarithmic slope is nominally -24.5 mV/dB.
