GENERAL DESCRIPTION
The ADG741/ADG742 are monolithic CMOS SPST switches.
These switches are designed on an advanced submicron process
that provides low power dissipation yet high switching speed,
low on resistance, low leakage currents and –3 dB bandwidths of
greater than 200 MHz can be achieved.
The ADG741/ADG742 can operate from a single 1.8 V to 5.5 V
supply, making it ideal for use in battery-powered instruments
and with Analog Devices’ new generation of DACs and ADCs.
As can be seen from the Functional Block Diagrams, with a
logic input of “1” the switch of the ADG741 is closed, while
that of the ADG742 is open. Each switch conducts equally well
in both directions when ON.
The ADG741/ADG742 are available in 6-lead SC70 package.
PRODUCT HIGHLIGHTS
1. 1.8 V to 5.5 V Single Supply Operation. The ADG741/
ADG742 offer high performance, including low on resistance
and fast switching times and is fully specified and guaranteed
with 3 V and 5 V supply rails.
2. Very Low RON (3 Ω max at 5 V, 5 Ω max at 3 V). At 1.8 V
operation, RON is typically 40 Ω over the temperature range.
3. On-Resistance Flatness RFLAT(ON) (1 Ω max).
4. –3 dB Bandwidth >200 MHz.
5. Low Power Dissipation. CMOS construction ensures low
power dissipation.
6. Fast tON/tOFF.
7. Tiny 6-Lead SC70 package.
