Overview

The LTC2217IUP 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 LTC2217IUP and LTC222 to interface directly to most microprocessor buses. The switches have 65 Ohms typical on resistance and a very high off resistance. 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 LTC2217IUP and LTC222 are designed for applications such as microprocessor controlled programmable gain amplifiers, automatic test equipment, communication systems, and data acquisition systems. The LTC2217IUP is normally closed and the LTC222 is normally open as shown in the Logic Table.
