MAX4528 19-1325 Rev 0 1/98 Low-Voltage, Phase-Reversal Analog Switch General Description Features The MAX4528 low-voltage, CMOS analog IC is config- 5pC (max) Charge Injection ured as a phase-reversal switch and optimized for high- 110 Signal Paths with 5V Supplies speed applications such as chopper amplifiers. It operates from a +2.7V to +12V single supply or from Rail-to-Rail Signal Handling 2.7V to 6V dual supplies. Transition Time <100ns with 5V Supplies On-resistance (110 max) is matched between switch- es to 7 (max). Each switch can handle Rail-to-Rail 1.0A (max) Current Consumption analog signals. The leakage current is only 0.5nA at >2kV ESD Protection per Method 3015.7 +25C and 20nA at +85C. All digital inputs have 0.8V to 2.4V logic thresholds, ensuring both TTL- and TTL/CMOS-Compatible Input CMOS-logic compatibility.

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. ELECTRICAL CHARACTERISTICS: 5V Dual Supplies (V+ = 5V, V- = -5V, V = 2.4V, V = 0.8V, T = T to T , unless otherwise noted. Typical values are at T = +25C.)
