The MAX391/MAX392/MAX393 are precision, quad,
single-pole/single-throw (SPST) analog switches
designed to operate at +3V, +5V, or ±5V. The MAX391
has four normally closed (NC) switches, and the
MAX392 has four normally open (NO) switches. The
MAX393 has two NO and two NC switches. All three
devices offer low leakage (100pA max) and fast switching
speeds (tON ≤ 130ns, tOFF ≤ 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 MAX391/MAX392/MAX393 offer
guaranteed 2Ω max channel-to-channel matching, 30Ω
max on-resistance (RON), and 4Ω max RON flatness
over the specified range.
These switches are also fully specified for single +5V
operation, with 2Ω max RON match, 60Ω max RON, 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.
