LTC221/LTC222

Micropower, Low Charge

Injection, Quad CMOS Analog

Switches with Data Latches

FEATURES

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.

Thesignalrangeis±15Vwithasupplyvoltageof±15Vand

0Vto5Vwithasingle5Vsupply.Theswitcheshavespecial

charge compensation circuitry which greatly reduces

charge injection to a maximum of±25pC (±15V supplies).
