AD8307

低成本DC - 500 MHz的92分贝对数放大器 Low Cost DC-500 MHz, 92 dB Logarithmic Amplifier

Product Details

The is the first logarithmic amplifier made available in an 8-lead SOIC_N package. It is a complete 500 MHz monolithic demodulating logarithmic amplifier based on the progressive compression successive detection technique, providing a dynamic range of 92 dB to ±3 dB law conformance and 88 dB to a tight ±1 dB error bound at all frequencies up to 100 MHz. The AD8307 is extremely stable and easy to use, requiring no significant external components. A single-supply voltage of 2.7 V to 5.5 V at 7.5 mA is needed. A fast acting CMOS-compatible control pin can disable the AD8307 to a standby current of 150 μA.

The AD8307 operates over the industrial temperature range of −40°C to +85°C and is available in an 8-lead SOIC package and an 8-lead PDIP.
