Improved Second Source for DG2O1A/DG202
The LTC
201A, LTC202, and LTC203 are micropower,
quad CMOS analog switches which typically dissipate only
250W from ±15V supplies and 40W from a single 5V
supply. The switches have 65 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.
