GENERAL DESCRIPTION
The AD8313 is a complete multistage demodulating logarithmic
amplifier that can accurately convert an RF signal at its input to
an equivalent decibel-scaled value at its dc output. The AD8313
maintains a high degree of log conformance for signal frequencies
from 0.1 GHz to 2.5 GHz. Application is straightforward,
requiring only a single supply of 2.7 V to 5.5 V and the addition
of a suitable input and supply decoupling. Operating on a 3 V
supply, its 13.7 mA consumption (for TA = 25°C) is only 41 mW.
A power-down feature is provided; the input is taken high to
initiate a low current (20 µA) sleep mode, with a threshold at
half the supply voltage.
The AD8313 is fabricated on Analog Devices, Inc., advanced
25 GHz silicon bipolar IC process and is available in an 8-lead
MSOP package. The operating temperature range is −40°C to
+85°C.
