GENERAL DESCRIPTION
The ADG904-EP is a wideband analog 4:1 multiplexer that uses
a CMOS process to provide high isolation and low insertion
loss to 1 GHz. The ADG904-EP is an absorptive/matched mux
with 50 Ω terminated shunt legs. This device is designed such
that the isolation is high over the dc to 1 GHz frequency range.
The ADG904-EP switches one of four inputs to a common
output, RFC, as determined by the 3-bit binary address lines
A0, A1, and
EN
. A Logic 1 on the
EN
pin disables the device.
The device has on-board CMOS control logic, which eliminates
the need for external control circuitry. The control inputs are both
CMOS and LVTTL compatible. The low power consumption of
this device makes it ideally suited for wireless applications and
general-purpose high frequency switching.
Additional application and technical information can be found
in the ADG904 data sheet.
PRODUCT HIGHLIGHTS
1. 37 dB off isolation at 1 GHz.
2. 1.1 dB insertion loss at 1 GHz.
3. 20-lead LFCSP package.

Video feedthrough is the dc transience at the output of any port of the switch when the control voltage is switched from high to low or low to high in a 50 Ω test
setup, measured with 1 ns rise time pulses and 500 MHz bandwidth.
