a DC-Coupled Demodulating
120 MHz Logarithmic Amplifier
AD640
signal output at +50 dB (referred to input) is provided to operate
AD640s in cascade.
The logarithmic response is absolutely calibrated to within ±1 dB
for dc or square wave inputs from ± 0.75 mV to ± 200 mV, with
an intercept (logarithmic offset) at 1 mV dc. An integral X10
attenuator provides an alternative input range of ± 7.5 mV to
± 2 V dc. Scaling is also guaranteed for sinusoidal inputs.
The AD640B is specified for the industrial temperature range of
–40°C to +85°C and the AD640T, available processed to MILSTD-883B, for the military range of –55°C to +125°C. Both are
available in 20-lead side-brazed ceramic DIPs or leadless chip
carriers (LCC). The AD640J is specified for the commercial
temperature range of 0°C to +70°C, and is available in both
20-lead plastic DIP (N) and PLCC (P) packages.
This device is now available to Standard Military Drawing
