Phase-Reversal Analog Switches
_______________General Description
The MAX4526/MAX4527 are CMOS analog ICs configu r e d as phase-reversal switches. The MAX4526 is optimized for high-speed applications, such as chopp e r amplifiers, while the MAX4527 is optimized for low-power applications. The MAX4526/MAX4527 operate from a +4.5V to +36V single supply or ±4.5V to ±18V dual supplies. On-resistance (175 max) is matched between switches to 8 maximum. Each switch can handle rail-to-rail analog s i g n a l s . Maximum leakage current is only 0.5nA at +25°C and 10nA at +85°C. All digital inputs have 0.8V to 2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility.

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.
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.

The algebraic convention is used in this data sheet; the most negative value is shown in the minimum column. Guaranteed by design. RON = RON(MAX) - RON(MIN). Resistance flatness is defined as the difference between the maximum and minimum values of on-resistance as measured over the specified analog-signal range. Note 6: Leakage current is 100% tested at maximum rated hot temperature, and is guaranteed by correlation at TA = +25°C and minimum rated cold temperature. Note 7: Off-isolation = 20log10 [(VX or VY) / (VA or VB)], VX or VY = output, VA or VB = input to off switch. Note 2: Note 3: Note 4: Note 5:
