AD606JN
The AD606 is a complete, monolithic logarithmic amplifier
using a 9-stage ?successive-detection? technique. It provides
both logarithmic and limited outputs. The logarithmic output is
from a three-pole post-demodulation low-pass filter and provides
a loadable output voltage of 0.1 V dc to 4 V dc. The logarithmic scaling is such that the output is 0.5 V for a sinusoidal
input of ?75 dBm and 3.5 V at an input of 5 dBm; over this
range the logarithmic linearity is typically within ?0.4 dB. All
scaling parameters are proportional to the supply voltage.
AD620 Amplifier IC DIP-8 (Low Power)
AD620 Amplifier IC is low-cost, high-accuracy amplifiers that require only one external resistor to set gains of 1 to 10,000. These amplifiers feature 8-lead SOIC and DIP packaging that is smaller than discrete designs. The AD620 instrumentation amplifiers offer lower power and high accuracy of 40ppm (maximum) nonlinearity. In addition to this, these amplifiers also provide a low offset voltage of 50?V (maximum) and an offset drift of 0.6?V/?C (maximum). The low input bias current of 1nA (maximum) is made possible with the use of Super?eta processing in the input stage. Typical applications include battery-powered, portable, and medical devices.

AD623 Instrumentation Amplifier IC DIP-8
The AD623 is an integrated. or dual-supply instrumentation amplifier that delivers rail-to-rail output swing using supply voltages from 3 V to 12 V. The AD623 offers superior user flexibility by allowing single gain set resistor programming and by conforming to the 8-lead industry standard pin out configuration_ With no external resistor, the AD623 is configured for unity gain (G I), and with an external resistor, the AD623 can be programmed for gains of up to The superior accuracy of the AD623 is the result of increasing ac common -mode rejection ratio (CMRR) coincident with increasing gain; line noise harmonics are rejected due to constant CAIRR up to 200 Hz.
AD640TE/883B
The AD640 is a complete monolithic logarithmic amplifier. A single
AD640 provides up to 50 dB of dynamic range for frequencies
from dc to 120 MHz. Two AD640s in cascade can provide up to
95 dB of dynamic range at reduced bandwidth. The AD640 uses a
successive detection scheme to provide an output current proportional to the logarithm of the input voltage. It is laser calibrated to
close tolerances and maintains high accuracy over the full military
temperature range using supply voltages from ?4.5 V to ?7.5 V.
The AD640 comprises five cascaded dc-coupled amplifier/limiter
stages, each having a small signal voltage gain of 10 dB and a ?3 dB
bandwidth of 350 MHz. Each stage has an associated full-wave
detector, whose output current depends on the absolute value of its
input voltage. The five outputs are summed to provide the video
output (when low-pass filtered) scaled at 1 mA per decade (50 ?A
per dB). On chip resistors can be used to convert this output current to a voltage with several convenient slope options.
AD654JR
The AD654 is a monolithic V/F converter consisting of an input
amplifier, a precision oscillator system, and a high current output
stage. A single RC network is all that is required to set up any
full scale (FS) frequency up to 500 kHz and any FS input voltage
up to ? 30 V. Linearity error is only 0.03% for a 250 kHz FS,
and operation is guaranteed over an 80 dB dynamic range. The
overall temperature coefficient (excluding the effects of external
components) is typically ?50 ppm/?C. The AD654 operates from
a single supply of 5 V to 36 V and consumes only 2.0 mA quiescent current
