GENERAL DESCRIPTION

The ADL5519 is a dual-demodulating logarithmic amplifier that incorporates two AD8317s. It can accurately convert an RF input signa

l 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

portional to the temperature over the operating temperature

pro range of the device.

The ADL5519 maintains accurate log conformance for signals

m 1 MHz to 8 GHz and provides useful operation to 10 GHz.

fro The ±3 dB dynamic range is typically 62 dB and has a ±1 dB dynamic range of >50 dB (re: 50 ). 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

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 sim

ultaneously. 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

rol voltage to a variable gain amplifier (VGA). Special

a cont 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 ava

ilable in a 5 mm × 5 mm, 32-lead LFCSP with an operating temperature range of −40°C to +125°C.
