The MAX392 are precision, quad, single-pole/single-throw (SPST) analog switches designed to operate at +3V, +5V, or ±5V. The MAX392 has four normally open (NO) switches. All three devices offer low leakage (100pA max) and fast switching speeds (t_ON ≤ 130ns, t_OFF ≤ 75ns). Power consumption is just 1µW—ideal for battery-operated equipment. All devices operate from a single +3V to +15V supply or from dual ±3.0V to ±8V supplies.

With ±5V supplies, the MAX392 offer guaranteed 2Ω max channel-to-channel matching, 30Ω max on-resistance (R_ON), and 4Ω max R_ON flatness over the specified range.

These switches are also fully specified for single +5V operation, with 2Ω max R_ON match, 60Ω max R_ON, and 6Ω max flatness.

These low-voltage switches also offer 5pC max charge injection, and ESD protection is greater than 2000V, per method 3015.7.
