Caution: The absolute maximum V+ to V- differential

voltage is 13V. Typical “±6 Volt” or “12 Volt” sup-

plies with ±10% tolerances can be as high as 13.2V

from V+ to V-. This voltage can damage the

MAX4598. Even ±5% tolerance supplies may have

overshoot or noise spikes that exceed 13V.

Single-Supply Operation

The MAX4598 operates from a single supply between

+2.7V and +12V when V- is connected to GND. All of

the bipolar precautions must be observed. However,

these parts are optimized for ±5V operation, and most

AC and DC characteristics are degraded significantly

when departing from ±5V. As the overall supply voltage

(V+ to V-) is lowered, switching speed, on-resistance,

off-isolation, and distortion are degraded (see

Typical

Operating Characteristics).

Single-supply operation also limits signal levels and

interferes with grounded signals. When V- = 0, AC sig-

nals are limited to -0.3V. Voltages below -0.3V can be

clipped by the internal ESD-protection diodes, and the

parts can be damaged if excessive current flows.

Power Off

When power to the MAX4598 is off (i.e., V+ = V- = 0),

the Absolute Maximum Ratings still apply: neither logic-

level inputs on NO_ nor signals on COM_ can exceed

±0.3V. Voltages beyond ±0.3V cause the internal ESD-

protection diodes to conduct, and the parts can be

damaged if excessive current flows.
