GENERAL DESCRIPTION
The ADL5519 is a dual-demodulating logarithmic amplifier that
incorporates two AD8317s. It can accurately convert an RF
input signal into a corresponding decibel-scaled output. The
ADL5519 provides accurately scaled, independent, logarithmic
output voltages for both RF measurement channels. The device
has two additional output ports, OUTP and OUTN, that
provide the measured differences between the OUTA and
OUTB channels. The on-chip channel matching makes the log
amp outputs insensitive to temperature and process variations.
The temperature sensor pin provides a scaled voltage that is
proportional to the temperature over the operating temperature
range of the device.
The ADL5519 maintains accurate log conformance for signals
from 1 MHz to 8 GHz and provides useful operation to 10 GHz.
The ±3 dB dynamic range is typically 62 dB and has a ±1 dB
dynamic range of >50 dB (re: 50 Ω). The ADL5519 has a response
time of 6 ns/8 ns (fall time/rise time) that enables RF burst detection to a pulse rate of greater than 50 MHz. The device provides
unprecedented logarithmic intercept stability vs. ambient
Rev. C
temperature conditions. A supply of 3.3 V to 5.5 V is required
to power the device. Current consumption is typically 60 mA,
and it decreases to less than 1 mA when the device is disabled.
The device is capable of supplying four log amp measurements
simultaneously. Linear-in-dB measurements are provided at
OUTA and OUTB with conveniently scaled slopes of −22 mV/dB.
The log amp difference between OUTA and OUTB is available
as differential or single-ended signals at OUTP and OUTN. An
optional voltage applied to VLVL provides a common-mode
reference level to offset OUTP and OUTN above ground. The
broadband output pins can support many system solutions.
Any of the ADL5519 output pins can be configured to provide
a control voltage to a variable gain amplifier (VGA). Special
attention has been paid to minimize the broadband noise of the
output pins so that they can be used for controller applications.
The ADL5519 is fabricated on a SiGe bipolar IC process and is
available in a 5 mm × 5 mm, 32-lead LFCSP with an operating
temperature range of −40°C to +125°C.
