LMH6505 linear-in-db variable gain amplifier 100MHZ vca
100MHz Linear-in-dB Voltage Controlled
To provide ease of use when working with a single supply, the VG range is set to be from 0V to +2V relative to the ground pin potential (pin 4). VG input impedance is high in order to ease drive requirement. In single supply operation, the ground pin is tied to a "virtual" half supply.
The LMH6505's gain control is linear in dB for a large portion of the total gain control range from 0 dB down to -85 dB @ 25 C, as shown below. This makes the device suitable for AGC applications. For linear gain control applications, see the LMH6503 .
