LTC201A - Micropower, Low Charge Injection, Quad CMOS Analog Switches - Linear Technology（凌力尔特）

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 65 Ohm 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 threedevices are differentiated by the type of switch action, as shown in the logic table.
