±15V 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.
