Linear Technology LTC202
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.FEATURES

● Charge Injection ±15V Supplies ................................. ±25pC Max Single 5V Supply .................................. 2pC Typ
● RON ............................................................. 65Ω Typ
● Signal Range .................................................... ±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.
