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.
