Low-Voltage, Phase-Reversal Analog Switch
________________General Description
The MAX4528 low-voltage, CMOS analog IC is configured as a phase-reversal switch and optimized for highs p e e d applications such as chopper amplifiers. It operates from a +2.7V to +12V single supply or from ±2.7V to ±6V dual supplies. On-resistance (110 max) is matched between switches to 7 (max). Each switch can handle Rail-to-Rail® analog signals. The leakage current is only 0.5nA at +25°C and 20nA at +85°C. All digital inputs have 0.8V t o 2.4V logic thresholds, ensuring both TTL- and CMOS-logic compatibility. F o r higher voltage operation, see the MAX4526/ MAX4527 data sheet.

Note 1: Signals on IN, A, B, X, or Y exceeding V+ or V- are clamped by internal diodes. Limit forward-diode current to maximum current rating. Note 2: All leads are soldered or welded to PC boards.
Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
