9-1136; Rev 6; 7/07 Quad, Low-Voltage, SPST Analog Switches Features The MAX4521/MAX4522/MAX4523 are quad, low-voltage, single-pole/single-throw (SPST) analog switches. On-resistance (100Ω max) is matched between switches to 4Ω max, and is flat (12Ω max) over the specified signal range. Each switch can handle rail-to-rail analog signals. The off-leakage current is only 1nA at +25°C and 10nA at +85°C.

MAX4521/MAX4522/MAX4523 Quad, Low-Voltage, SPST Analog Switches Applications Information Power-Supply Considerations Overview The MAX4521/MAX4522/MAX4523 construction is typical of most CMOS analog switches. They have three supply pins: V+, V-, and GND. V+ and V- are used to drive the internal CMOS switches, and they set the limits of the analog voltage on any switch. Reverse ESDprotection diodes are internally connected between each analog-signal pin and both V+ and V-.
