GENERAL DESCRIPTION  
The AD8367 is a high performance 45 dB variable gain  
amplifier with linear-in-dB gain control for use from low  
frequencies up to several hundred megahertz. The range,  
flatness, and accuracy of the gain response are achieved using  
Analog Devices’ X-AMP® architecture, the most recent in a  
series of powerful proprietary concepts for variable gain  
applications, which far surpasses what can be achieved using  
competing techniques.  
The analog gain-control input is scaled at 20 mV/dB and runs  
from 50 mV to 950 mV. This corresponds to a gain of −2.5 dB  
to +42.5 dB, respectively, when the gain up mode is selected and  
+42.5 dB to −2.5 dB, respectively, when gain down mode is  
selected. The gain down, or inverse, mode must be selected  
when operating in AGC in which an integrated square-law  
detector with an internal setpoint is used to level the output to  
354 mV rms, regardless of the crest factor of the output signal.  
A single external capacitor sets up the loop averaging time.  
The input is applied to a 9-stage, 200 Ω resistive ladder network.  
Each stage has 5 dB of loss, giving a total attenuation of 45 dB.  
At maximum gain, the first tap is selected; at progressively  
lower gains, the tap moves smoothly and continuously toward  
higher attenuation values. The attenuator is followed by a  
42.5 dB fixed gain feedback amplifier—essentially an  
operational amplifier with a gain bandwidth product of  
100 GHz—and is very linear, even at high frequencies. The  
output third order intercept is +20 dBV at 100 MHz (+27 dBm,  
re 200 Ω), measured at an output level of 1 V p-p with VS = 5 V.  
The AD8367 can be powered on or off by a voltage applied to  
the ENBL pin. When this voltage is at a logic LO, the total  
power dissipation drops to the milliwatt range. For a logic HI,  
the chip powers up rapidly to its normal quiescent current of  
26 mA at 25°C. The AD8367 is available in a 14-lead TSSOP  
package for the industrial temperature range of −40°C to +85°C.
