The AD8310 is a fast, voltage-output DC to 440 MHz, 95 dB logarithmic amplifier. It features a multistage demodulating logarithmic amplifier, voltage output, rise time less than 15 ns, high current capacity, and a 95 dB dynamic range.
The AD8310 from Analog Devices is a voltage‑output, demodulating logarithmic amplifier covering DC to 440 MHz. It provides a 95 dB dynamic range, a 24 mV/dB slope and an intercept of –108 dBV, making it suitable for signal‑level conversion, antenna‑power measurement and radar/sonar processing.
The device operates from a single 2.7 V to 5.5 V supply, draws only 8 mA quiescent current, and can source up to 25 mA into a grounded load with a rise time under 15 ns. It is specified for –40 °C to +85 °C operation and is available in an 8‑lead MSOP package.
