LTC201A/LTC202/LTC203 Micropower, Low Charge Injection, Quad CMOS Analog Switches FEATURES ■ ■ ■ ■ ■ ■ ■ ■ ■ DESCRIPTIO 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 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. , LTC and LT are registered trademarks of Linear Technology Corporation.
