DESCRIPTIO
The LTC®201A, LTC202, and LTC203 are micropower,
quad CMOS analog switches which typically dissipate only
250µW from ±15V supplies and 40µW from a single 5V
supply. The switches have 65Ω typical on resistance
and a very high off resistance. A break-before-make
characteristic, inherent in these switches, prevents the
shorting of two channels. With a supply voltage of ±15V,
the signal range is ±15V. These switches have special
charge compensation circuitry which greatly reduces
charge injection to a maximum of ±25pC (±15V supplies).

The LTC201A, LTC202, and LTC203 are designed for
applications such as programmable gain amplifiers,
analog multiplexers, sample-and-hold circuits, precision
charge switching and remote switching. These three
devices are differentiated by the type of switch action, as
shown in the logic table.

of a device may be impaired.
Note 2: Signals on S, D, or IN exceeding V + or V – will be clamped by
internal diodes. Limit forward diode current to maximum current rating.
