■ Micropower Operation ■ Single 5V or ±15V Supply Operation ■ Low Charge Injection ■ Low RON ■ Low Leakage ■ Guaranteed Break Before Make ■ Latch Resistant Design ■ TTL/CMOS Compatible ■ Improved Second Source for DG2O1A/DG202 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 Ω 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.

Note 1: Absolute Maximum Ratings are those values beyond which the life 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. Note 3: In-circuit ESD on the switch pins (S or D) exceeds 4kV (see test circuit). Note 4: Leakage current with a single 5V supply is guaranteed by correlation with the ±15V leakage current.
