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
(DESC) number 5962-9095501MRA and 5962-9095501M2A. FEATURES
Complete, Fully Calibrated Monolithic System
Five Stages, Each Having 10 dB Gain, 350 MHz BW
Direct Coupled Fully Differential Signal Path
Logarithmic Slope, Intercept and AC Response are
Stable Over Full Military Temperature Range …
