LTC221/LTC222
Micropower, Low Charge
Injection, Quad CMOS Analog
Switches with Data Latches
DESCRIPTIO
The LTC
®
221 and LTC222 are micropower, quad CMOS
analog switches which typically dissipate only 250µW
from
±15V
supplies and 40µW from a single 5V supply.
Onboard latches allow the LTC221 and LTC222 to inter-
face directly to most microprocessor buses. The switches
have 65Ω typical on resistance and a very high off resis-
tance. A break before make characteristic is inherent in
these switches to prevent the shorting of two channels.
The signal range is
±15V
with a supply voltage of
±15V
and
0V to 5V with a single 5V supply. The switches have special
charge compensation circuitry which greatly reduces
charge injection to a maximum of
±25pC
(±15V supplies).
The LTC221 and LTC222 are designed for applications
such as microprocessor controlled programmable gain
amplifiers, automatic test equipment, communication
systems, and data acquisition systems. The LTC221 is
normally closed and the LTC222 is normally open as
shown in the Logic Table.
